Throttle position sensor atau sensor TPS adalah komponen mobil yang terhubung dengan bagian katup gas throttle gas. Fungsi sensor TPS adalah untuk mengatur dan menyeimbangkan bahan bakar dan emisi pada mesin mobil. Komponen ini menyatu pada bodi throttle dan selalu terhubung dengan throttle valve katup gas. Namun, sebenarnya apa fungsi sensor TPS ini? Bagaimana cara kerjanya pada mobil? Agar lebih paham, Auto2000 akan membahas tentang fungsi dan cara kerja sensor TPS pada mobil. Fungsi Sensor TPS Fungsi yang utama adalah mendeteksi adanya perubahan pada throttle gas. Sensor ini bertugas untuk memastikan throttle gas tetap pada posisi serta sudut bukaan yang sesuai. Apabila terjadi pergeseran, maka sensor akan mengirimkan sinyal elektrik yang dikirim ke ECU Electronic Care Unit. Setelah sinyal tersebut diproses, kemudian akan dilakukan injeksi atau suplai bahan bakar ke dalam ruang bakar. Di samping itu, fungsi lain sensor TPS adalah Menjadi engine mode saat posisi throttle gas menutup biasanya saat mobil dalam kondisi idle, setengah membuka, dan terbuka penuh. Menjadi kontrol emisi, terutama saat throttle gas sedang dalam posisi terbuka penuh serta saat air conditioner mati. Mengontrol bahan bakar agar terhenti saat mesin melakukan posisi deselerasi perlambatan. Bertugas mengoreksi takaran perbandingan jumlah udara dan bahan bakar. Bertugas mengoreksi ada tidaknya peningkatan tenaga pada mesin.

Seperti yang telah disebutkan sebelumnya, fungsi sensor TPS adalah mendeteksi adanya perubahan posisi serta sudut bukaan throttle gas. Bagaimana sensor TPS bisa mendeteksi hal tersebut? Pertama, ada baiknya kita mengenal terlebih dahulu komponen pada sensor TPS. 1. Komponen Penyusun Sensor TPS Sensor TPS umumnya didesain dengan tiga kabel beberapa mobil memiliki sensor TPS dengan empat kabel. Tiga kabel ini terhubung dengan potensiometer. Pada sensor TPS, potensiometer berfungsi untuk mengukur posisi serta sudut bukaan throttle gas. Saat bekerja, potensiometer bertindak layaknya resistor yang selalu berubah-ubah tekanannya. Maka dari itu, sensor TPS memerlukan tiga buah kabel pembantu. Kabel pertama pada sensor TPS adalah untuk tegangan referensi, kabel kedua untuk tegangan balik, dan kabel ketiga untuk tahanan. 2. Bagaimana Sensor TPS bekerja? Saat Anda menghidupkan mobil, ECU akan mengirimkan tegangan output atau tegangan referensi 5v yang kemudian diterima sensor analog VREF. Dari sensor analog, tegangan kembali ke ECU melalui TP Signal. Saat mobil dalam kondisi idle atau nonaktif, tegangan yang keluar dari sensor nilainya di bawah 0,7 Volt. Sedangkan dalam kondisi beban penuh, tegangan yang keluar dapat mencapai 4,5 Volt. Potensiometer dapat berubah-ubah tekanannya. Maka dari itu, tegangan keluar atau output yang dihasilkan sensor TPS pun selalu berubah. Potensiometer dapat bergeser dari tegangan paling rendah titik P1 hingga tegangan paling tinggi titik P6. Semua bergantung pada tekanan yang diterima pedal gas sangat berperan apalagi jika Anda menyetir mobil manual.

Sensorposisi throttle (TPS) adalah sensor yang digunakan untuk memantau posisi throttle mobil. Sensor ini biasanya terletak di kupu-kupu spindle / poros sehingga dapat langsung memonitor posisi throttle. Bentuk yang lebih maju dari sensor juga digunakan, misalnya throttle position sensor ekstra tertutup (CTPS) dapat digunakan untuk menunjukkan bahwa throttle benar-benar tertutup.

– Anda perlu mengenali tanda sensor TPS rusak atau tidak bekerja dengan baik. Tetapi untuk mengenalinya tentu saja diperlukan pengetahuan dan pemahaman bagaimana cara kerja sensor TPS. Jika keduanya telah Anda pahami dengan baik, barulah Anda dapat melangkah ke bagian selanjutnya dalam proses troubleshooting masalah sensor TPS yakni ke prosedur pemeriksaan sensor TPS. Sebenarnya prosedur pemeriksaan sensor TPS tidak lah sulit. Tetapi jika Anda khawatir malah akan menambah kerusakan bahkan mungkin ke masalah ECU mobil, silahkan Anda meminta bantuan teknisi di bengkel ternama kesayangan Anda. Update artikel 23 Novemer 2022 – Pukul Sebelum melangkah ke prosedur pemeriksaan TPS lebih jauh perhatikan catatan berikut ini. CATATAN Pengerjaan operasi berikut hanya untuk jenis three state throttle valve switch. Dalam beberapa kasus, kita dapat menghubungkan sakelar idle dan sakelar beban penuh secara terpisah. Juga ada sakelar idle dan beban penuh yang terpisah. Pada beberapa model Rover, sakelar katup throttle terletak di pedal akselerator. Terlepas dari lokasi sakelar, kita dapat melakukan prosedur verifikasi dengan cara yang sama untuk semua jenis sensor. Yang pertama kita akan lakukan adalah prosedur pemeriksaan TS. Silahkan Anda pahami tentang cara kerja TS pada artikel sebelumnya. Pertama – Periksa Tegangan TS Tiga kabel yang masuk ke kopling sakelar throttle adalah kabel grounding, idle mode signal dan sinyal beban penuh atau full load signal. Hubungkan terminal negatif voltmeter ke ground engine – lihat cara menggunakan Voltmeter jika belum tahu. Tentukan terminal ground, idling, dan beban penuh sensor. Nyalakan kunci kontak posisikan ON, tetapi jangan menyalakan mesin. Hubungkan terminal positif voltmeter ke kabel, yang terhubung ke kontak sinyal idle dari saklar throttle. Voltmeter harus membaca tegangan 0V. Jika berbunyi tegangan longgarkan sekrup dan sesuaikan sakelar sehingga voltmeter membaca tegangan nol. CATATAN Pada beberapa mobil, sakelar katup throttle tidak dapat disesuaikan. Kedua – Periksa hambatan TS Konektor throttle terputus. Hubungkan ohmmeter antara terminal ground dan mode idle. Ketika sakelar katup throttle dihidupkan, ohmmeter harus membaca resistansi sekitar 0 . Buka katup throttle secara perlahan dan ketika sakelar terbuka resistensi harus sama dengan tak berhingga infinit dan tetap sama bahkan jika throttle terbuka penuh. Hubungkan ohmmeter antara ground dan terminal mode beban penuh. Ketika sakelar throttle ditutup, ohmmeter harus membaca pemutus sirkuit resistansi tak berhingga. Buka katup throttle secara perlahan. Ketika saklar terbuka itu harus berbunyi klik dan hambatan harus tetap sama hingga tak berhingga. Ketika sudut bukaan katup throttle menjadi lebih besar dari 72 derajat, resistansi akan sama dengan 0 . Jika sakelar tidak bekerja dengan cara yang dijelaskan di atas, dan sakelar dinyalakan dan dimatikan tidak dapat diatur dengan menekuk tuas penggerak katup throttle, kemungkinan besar sakelar throttle rusak. Ketiga – Periksa kemungkinan kerusakan di dalam TS Dalam langkah ini, ada beberapa hal penting yang harus anda pastikan kondisinya. Berikut adalah beberapa di antara yang paling penting dalam langkah ini. 1. Tidak bisa mendapatkan tegangan 0 V katup throttle tertutup Periksa kondisi katup throttle. Periksa koneksi sakelar ke ground. Lakukan pengukuran resistansi sakelar. Jika tegangan normal dengan katup throttle tertutup, buka katup throttle dengan tajam, sakelar harus berbunyi klik, dan voltase akan naik hingga 2. Tegangan rendah atau hilang katup throttle dibuka Periksa apakah terminal sakelar mode idle tidak terhubung ke ground. Lepaskan koneksi konektor switch dan periksa keberadaan tegangan V pada kontak mode idle. Jika tidak ada tegangan, lakukan pemeriksaan berikut periksa hubungan kawat sinyal mode idle antara sakelar dan pengontrol onboard; Jika kabel sakelar baik, periksa semua koneksi catu daya dan ground dari pengontrol onboard. Jika tidak ada masalah, kesalahan mungkin ada pada pengontrol onboard. 3. Tegangan normal katup throttle dibuka Hubungkan terminal positif voltmeter ke kabel, yang terhubung ke kontak saklar mode beban penuh. Ketika katup throttle dalam keadaan idle atau sedikit terbuka, voltmeter harus membaca tegangan V. 4. Tegangan rendah atau hilang katup throttle ditutup atau sedikit terbuka Periksa koneksi ground. Periksa apakah kontak mode beban penuh dari sakelar throttle tidak terhubung ke ground. Lepaskan koneksi konektor switch. Periksa keberadaan tegangan V pada kontak mode beban penuh konektor. Jika tidak ada tegangan, lakukan pemeriksaan berikut periksa hubungan kawat sinyal mode siaga antara sakelar dan pengontrol onboard; Jika kabel sakelar baik, periksa semua koneksi catu daya dan ground dari pengontrol onboard. Jika tidak ada masalah, kesalahan mungkin ada pada pengontrol onboard. 5. Tegangan normal katup throttle tertutup atau sedikit terbuka Buka sepenuhnya katup throttle. Ketika sudut bukaan menjadi lebih dari 72 derajat, tegangan harus turun ke nol. Jika tegangan tidak turun, kemungkinan besar throttle switch tidak berfungsi. Prosedur pemeriksaan Sensor TPS Selanjutnya kita akan melihat prosedur pemeriksaan sensor TPS. Berikut adalah langkah-langkah prosedur pemeriksaan sensor TPS. Pertama – Periksa tegangan TPS Hubungkan terminal negatif voltmeter ke ground engine. Tentukan terminal ground, idle dan beban penuh. CATATAN Kebanyakan potensiometer throttle memiliki tiga terminal, tetapi beberapa mungkin memiliki dan kontak tambahan, yang berfungsi sebagai sakelar throttle. Jika ada kontak seperti itu, itu harus diperiksa seperti dijelaskan di atas untuk saklar throttle. Hubungkan terminal positif voltmeter ke kabel yang terhubung ke sinyal kontak dari potensiometer katup throttle. Nyalakan kunci kontak ON, tetapi jangan menyalakan mesin. Dalam kebanyakan sistem pembacaan tegangan harus kurang dari 0,7 V. Buka dan tutup katup throttle beberapa kali, dengan memeriksa kelancaran tegangan yang meningkat. Kedua – Periksa hambatan TPS Hubungkan ohmmeter antara wiper potensiometer dan terminal tegangan referensi atau antara penghapus potensiometer dan ground. Buka dan tutup katup throttle beberapa kali dan periksa kelancaran variasi resistensi. Jika resistansi potensiometer tidak terbatas atau nol, ini menunjukkan kegagalan fungsi kerja. Sensor tidak menampilkan nilai yang tepat dari resistansi potensiometer throttle. Salah satu alasannya adalah banyak produsen tidak mempublikasikan data kontrol. Fakta bahwa setingan tetap untuk resistansi potensiometer dalam batas kurang penting daripada operasi yang tepat dari potensiometer, yaitu hambatan perubahan halus saat menggerakkan katup throttle. Hubungkan ohmmeter antara ground dan terminal tegangan referensi. Hambatan harus konstan. Jika resistansi tidak terbatas atau rendah, maka kita harus mengganti potensiometer. Ketiga – Periksa kemungkinan kerusakan di dalam TPS 1. Sinyal keluaran kacau Sinyal output kacau diamati ketika sinyal tegangan berubah dengan cepat, turun ke nol dan menghilang. Ketika sinyal keluaran potensiometer katup throttle kacau, potensiometer yang rusak biasanya menjadi alasannya. Dalam hal ini, potensiometer harus diganti. 2. Sinyal tegangan hilang Periksa keberadaan tegangan referensi pada terminal daya potensiometer throttle. Periksa kondisi kontak grounding potensiometer. Periksa kabel sinyal yang menghubungkan potensiometer throttle ke pengontrol onboard. Jika catu daya dan ground buruk, periksa hubungan kabel antara potensiometer dan pengontrol onboard. Jika kabel potensiometer baik, periksa semua koneksi suplay daya dan ground dari pengontrol onboard. Jika sudah tidak ada masalah, kemungkinan besar alasannya adalah onboard controller itu sendiri. 3. Sinyal output atau tegangan referensi sama dengan tegangan baterai Periksa korsleting pada kabel yang terhubung ke terminal positif baterai mobil mobil atau kabel catu daya. Itu tadi prosedur pemeriksaan sensor TPS dan sensor TS. Dalam melakukannya Anda harus hati-hati sekali. Ini semua berkaitan dengan masalah kelistrikan. Jangan sampai terjadi konsleting atau beberapa hal lain terkait dengan kelistrikan mobil Anda. Selamat mencoba dan semoga beruntung…! Untuk metode dan atau prosedur pemeriksaan sensor TPS throttle position sensor pada mobil yang berbeda, Anda dapat menonton video berikut ini;

The throttle position sensor in your car is used to monitor the air intake within the engine. Usually located near the valve that regulates the fluid from the sound and shaft, the position sensor monitors the throttle’s position. This throttle position sensor works in tandem with the engine control unit to properly control the engine airflow. Auto Repairs Are EXPENSIVE To keep your car working at the correct level, sometimes you need to troubleshoot and figure out any problems you are having with your engine system. To do this, you need to perform the necessary throttle position sensor test to figure out the main cause of the problem. Let’s find out the various transmissions sensors, the throttle position sensor’s steps, and the throttle position sensor replacement cost. By knowing this key information, you can determine if you should perform the throttle position sensor test or if you should bring your vehicle to a mechanic to perform this service. Transmission control module sensors To learn why it is imperative to perform the throttle position sensor test, you need to know the three most important transmission control module sensors. The throttle position sensor directly affects the inner workings and performance of the transmission. To figure out how the transmission throttle position sensor affects the module, you need to perform the throttle position sensor test. Throttle position sensor One of the sensors that send signals to the transmission control module is the throttle position sensor. This throttle position sensor provides an important data source, with information coming directly from the vehicle’s throttle position. If the throttle position sensor cannot send the proper data to the transmission, then this is a way to figure out how you know if your transmission control module is bad. To determine if the position sensor is faulty, you might need to perform the throttle position sensor test. The throttle position sensor’s signal lets the module know the amount of load being placed on the engine at one time or how much stress the engine is under. This information can help the transmission control module figure out if the car needs to upshift or downshift based on the position. The transmission control module can also analyze the data from the throttle position sensor, and then compare this information to the vehicle sensor speed data to determine which shift is most appropriate. If your vehicle is having trouble shifting, this is a way how you know if your transmission control module is bad. To figure out if the control module is bad, you might need to carry out the throttle position sensor test. Vehicle speed sensor The transmission control module uses the vehicle speed sensor to determine how fast the car is traveling. By realizing how fast the car is moving, the car will know the proper time to change gears based on the performance. If this sensor is not working properly or is functioning incorrectly, the transmission control module can select the wrong gear at the wrong time, causing the transmission to slip. This is how you know if your transmission control module is bad. Wheel speed sensor The wheel speed sensor data can help the transmission control module better know what the car is currently doing by the actions it is performing, so the TCM can properly adjust the shifting and gear changing accordingly. The wheel speed sensor also notifies the TPM of when to control and alter the torque converter’s function. Symptoms Of A Faulty Throttle Control Even though the throttle control position sensor and the throttle control are long-lasting and play a huge role in your system by providing various services, it can still break down. Like any other mechanical part in your car that is in charge of numerous functions, this system can undergo damage over time. There are key signs and symptoms to keep an eye out for when protecting your vehicle against any further damage that can enhance the repair cost. Jerking While Accelerating First, your vehicle might hesitate while accelerating, jerk while accelerating, or misfire in the engine. If you notice any of these symptoms or rough shifting, this is time to look at the overall electronic throttle repair cost. In addition, you should look at how to perform the throttle position sensor test. Trouble Changing Gears Second, your electronic throttle control can cause you to have difficulties changing gears. This can cause your gears to feel sticky, slow to change between gears, or trouble getting out of gear. In addition, another sign of a faulty electronic throttle control are issues displaying the power characteristics. This means that your car will display uneven data, leading to the necessity for the throttle position sensor test. Car Stalls Furthermore, if your car stalls without any noticeable reason, then this is a clear sign that you need to determine how to perform the throttle position sensor test. Engine stalling can be a sign of a severe issue and can even lead to an expensive engine replacement, so this problem needs to be figured out and fixed as soon as possible. Surging An additional symptom that might indicate you need to check into the electronic throttle control repair cost is quick and unintended surges in speed while driving. This is a huge safety problem since this can happen while you're behind another car or going around a curve. To prevent your car from going out of control, you need to perform a throttle position sensor test. Warning Lights Furthermore, clear signs that you have something wrong in your car can be easily seen by the dashboard warning system lights. Although these lights can come on for various reasons, some lights indicate that you need to get your car checked immediately – like the check engine light. Even though this light might appear for multiple reasons, that can differ depending on the severity, and you need to bring your car to a mechanic as soon as possible to determine if you need to run the throttle position sensor test. Decline In Fuel Economy Lastly, the final symptom of a faulty electronic throttle control is that there is a sharp decline in your fuel economy and your miles per gallon. If you realize that you cannot go as far in your car with the same amount of fuel as before, then this is a clear symptom that you need to bring your car to a trusted mechanic so they can perform the throttle position sensor test. How To Test a Throttle Position Sensor The most common throttle position sensor test is to measure the resistance or voltage. The test will measure the data at various positions, with the throttle being closed, partially open, or fully open. In this case, the first way to test the throttle position sensor is to use voltage. First, you need to open the hood and remove the cleaner assembly. Check and analyze the throttle plate and the throttle body’s walls to see if there are any contaminants or carbon buildup. Lastly, locate the throttle position sensor on the side of the throttle body. TPS Connected To Ground If your TPS is connected to the ground, you need to unplug the electrical connector and examine the connections for any dirt, debris build-up, and contaminants. Now, you have to set the digital multimeter to around 20 volts on the voltage scale. After the voltage has been set, turn the ignition key to the ON position. Connect the rest of the lead to the positive battery section. Once this is connected, use the black test lead to perform the throttle position sensor test to the three electrical terminals. If the terminals do not read 1 volt, there is a problem with the wiring. TPS Connected To Reference Voltage If your throttle position sensor is connected to the reference voltage instead of the ground, you need to perform different steps when learning how to perform the throttle position sensor test. First, you need to connect the black lead from the digital multimeter to the ground terminal on the throttle position sensor. Once you have done this, turn the ignition to the ON position without starting the engine. After this step has been completed, connect the red test lead to the other two terminals. If one of the terminals reads 5 volts, then the throttle position sensor is working correctly. However, if you do not receive the 5 volt reading from either of the two terminals, there is a problem in the circuit. This is a sure way to perform the throttle position sensor test. TPS Producing the Correct Signal Voltage To determine if the throttle position sensor test worked and is producing the correct voltage, you need to perform additional steps after completing the initial testing protocol. Back Probe the signal and ground terminals on the connector. Then, connect the red lead to the signal wire and the black test lead from the multimeter to the ground wire. Turn the key ON without starting the engine, ensuring the throttle is fully closed. If the digital multimeter reads between .2 to volts, then the throttle position sensor is working correctly. As you open the throttle plate, the digital multimeter should increase to 5 volts. If the throttle position sensor test does not reach 5 volts, this is a sign that the throttle position sensor needs to be replaced.

Today’s cars are equipped with advanced sensors for just about every system. While these sensors provide optimal operation, they can also fail and cause trouble. If you need to deal with the throttle body sensor, it’s important that you can reset it. In this guide, I discuss what the throttle position sensor is and show you how you can reset it. I also show you signs that something is wrong with the throttle body sensor and give you a few tips for cleaning the throttle body. The methods you use to reset the throttle position sensor on your car depend entirely on the car model you drive. On some car models, you can reset the throttle body sensor by disconnecting the battery, while on others you need to use a diagnostic tool to reset and calibrate it. Before you reset the throttle body sensor, you may want to ensure that it’s mechanically calibrated if that is possible on your car model. Here are some of the common methods for resetting a throttle position sensor 1. Use an OBD2 scanner The easiest way to reset a throttle sensor and calibrate it on most modern car models is to use an OBD2 scanner. However, to do this, you need to make sure that the diagnostic scanner you buy is compatible with your car engine and has a throttle sensor reset feature for your car model. You can find many OBD2 scanners for cheap, but it won’t help if it’s not compatible with your car, so you should do a lot of research before you decide to buy one. Additionally, for some car models, it is only possible to reset the throttle sensor manually. 2. Push Accelerator You might be able to reset the sensor without much effort. Turn on the vehicle without starting the engine and leave the key in the ON position. If you have a keyless start, just push the button one time, not enough to crank the engine over. Hold down the accelerator pedal for twenty seconds. You want it to go as close to the floor as possible. Release it slowly and turn the car off. Now, start the engine normally and go for a drive to see if the situation has improved. 3. Remove Fuse The sensor is an electronic aspect of the vehicle. It is run through a fuse. By pulling out the fuse, you cause a manual reset of the sensor. Find the fuse box and the appropriate fuse. This information can be found in the owner’s manual. Pull out the fuse and leave it out for ten minutes. After you replace it, the throttle body sensor should have reset. However, so will anything else that’s also run by that fuse. RELATED 8 Symptoms of a Bad Throttle Body & Replacement Cost 4. Drive the Vehicle In some cases, it takes driving the vehicle to reset the sensor. Start the engine and drive down the highway at maximum speeds. You want to be consistently over 40 mph. Once you get the car up to highway speeds, you should slowly accelerate and decelerate slightly. Give a few minutes in between each session. The sensor may reset, providing better responsiveness. 5. Disconnect Battery Whenever you want to reset something electronic, disconnecting the battery can help. Take off the negative cable from the battery. Allow the battery to remain disconnected for five minutes before reconnecting it. When you do this, everything electronic in the car will reset, including the clock and stereo preset. For this reason alone, most people prefer starting with one of the other methods first. 6. Drain Car Power Even when you remove the battery connection, many aspects of the car can retain power. If nothing else is working, you want to drain the power from every aspect of the car in hopes of resetting the sensor. Start by disconnecting the battery, both the positive and negative cables. Jump into the car and turn on the ignition and press the brake pedal. You may want to wait 10 to 30 minutes for this procedure. During this time, any power will drain from the vehicle. Reconnect the battery cables and start the engine. The sensor should be reset. 7. Idle Engine Crank the engine over and allow the car to idle for three minutes. Once the time is up, turn the car off. Go ahead and repeat these steps again. In a few models, you can turn the key ON without starting the engine with the same results. Reference the service manual to see what’s appropriate for your car. What is the Throttle Position Sensor TPS? The throttle position sensor TPS can be found alongside the throttle body. It’s a sensor that includes a magnetic disk to send electronic pulses to the engine control module ECM. This sensor alerts the computer about the position of the throttle, whether it is open or closed. When the car needs more speed, the throttle must open up. On the other side, the throttle must close when the car is slowing down. Additionally, during idling, the throttle must be mostly closed, still allowing gas to flow through to the engine. The computer utilizes the information received by the TPS to idle the idle speed. When you let off the accelerator pedal, the car needs to continue pumping gas so it doesn’t stall. The computer will also look at the cylinders to determine if they are receiving enough fuel to continue combustion. RELATED 5 Signs of a Bad Throttle Position Sensor Replacement Cost Signs of Defective Throttle Body Sensor 1. Check Engine Light When any sensor fails or isn’t optimized, the Check Engine Light can come on the dashboard. Because the engine control module is monitoring the throttle body sensor, you can expect this light to come on when there’s a problem. An error code will be stored in the computer that can be read with your OBDII scanner. In most cases, you might see Code P2119, which stands for “Throttle Actuator Control Throttle Body Range/Perfomance.” This is the code that occurs when the throttle sensor is out of range. 2. Rough Idle When the throttle body sensor isn’t working properly, the idle could be off. RPMs could drop or be higher than normal because of the defects. Not only can this cause the engine to stall, but your car could also go through more fuel than it should. With the air-fuel ratio imbalance, you want to have the problem resolved right away. 3. Trouble Accelerating There could be a lack of power when the sensor fails. Without the right amount of power, acceleration can be troublesome. Not only will there be some hesitation, but the car can also jerk. There’s also the chance that your car can accelerate on your own. If the butterfly valve opens on its own when it should be closed, the car can propel forward. On the other hand, the most probable symptom is that you will have trouble getting the car to go faster, even when you push down the gas pedal. 4. Limp Mode If the situation is dire, the car can go into limp mode. This default setting occurs whenever something is happening that has the potential to harm the engine. Power is cut off to certain car functions to ensure better protection. However, it’s hard to drive the vehicle in limp mode. You can put the four-way lights on to alert others to the trouble. If you only have to drive a short distance, you might be able to make it. Otherwise, you might consider having the vehicle towed for your protection. Steps to Clean the Throttle Body If there’s a problem with the throttle body itself, you might be able to clean it versus replacing it. Here are some general steps you could follow. Locate the throttle body. It is usually between the air filter and intake manifold. Normally, you can clean the throttle body without removing it. With a carburetor or brake cleaner and a microfiber cloth, carefully get rid of any carbon buildup or dirt. Test drive the car. You can gain more guidance by following the directions found in your car’s service manual. Otherwise, you need to visit a professional for more help. RELATED How to Clean a Throttle Body 10 Steps DIY FAQs Do you have to reset the computer after replacing the throttle position sensor? Most car models will reset and calibrate the throttle position sensor by itself after you replace the sensor and turn on the ignition. However, on some car models you may need to calibrate it manually or reset it by disconnecting the battery or using an OBD2 scanner. Does a throttle position sensor need to be calibrated? If your car has a throttle cable, you often must manually calibrate the throttle sensor according to a repair manual for your car model. If your car uses an electronic throttle, the car can calibrate the sensor automatically when you turn on the ignition. Is there a fuse for the throttle position sensor? There is no fuse for only the throttle position sensor in most car models. However, there should be a fuse for the engine control module that sends the power to the throttle position sensor. Check your owner’s manual for the fuse location. Does the throttle position sensor affect idle? Yes. A bad throttle sensor can affect the idle and result in a rough or unstable idle. If you suspect that the throttle position sensor is bad, you need to scan the trouble code memory with a code scanner. Categories Engine, Guides
