How To Calibrate (Reset) Throttle Position Sensor (7 Steps)

How To Calibrate Throttle Position Sensor

The throttle position sensor, or TPS, is a small sensor that tells the computer how far the throttle plate is open. The TPS is located on the side of the throttle body and is connected to the throttle shaft.

A throttle position sensor is a critical component in any vehicle. It helps the engine control module to regulate the amount of air entering the engine. If the throttle position sensor is not working properly, it can cause all sorts of problems with the engine, including poor fuel economy and decreased performance.

Many people don’t realize how important it is to calibrate their throttle position sensor (TPS). A properly calibrated TPS can save you a lot of money and time in the long run. Here’s a step-by-step guide on how to calibrate your TPS:

How To Calibrate Throttle Position Sensor

The Throttle cable is adjusted during the calibration of the throttle position sensor, which detects the lowest and greatest line pressures. Internally, this operation links those pressures to the 0 percent and 100 percent throttle positions. These settings are then utilized to determine the actual throttle percentage.

After installing an electronic throttle in your vehicle, you’ll need to take some time to calibrate, reprogram and reset the electronic throttle. By doing this, you’ll ensure that the throttle is working effectively and efficiently. Here’s a quick guide on how to calibrate your new electronic throttle:

First of all, start the car, allow it to heat up, and save the charge on the battery, it is important to turn off all of the car’s electrical accessories when they are not needed. This includes items such as the radio, heated seats, and air conditioning.

The procedure for the calibration of the Throttle Position Sensor is explained below.

  1. Start the ignition switch, make sure the accelerator pedal is completely disengaged, and then wait for three seconds.
  2. The accelerator pedal must be fully depressed and fully released immediately five times in five seconds.
  3. Wait 10 seconds after finishing the last step before fully depressing the accelerator.
  4. Wait for the Check Engine Light to remain ON and stops flickering for around 20 seconds.
  5. After the Check Engine Light is illuminated, fully disengage the accelerator pedal of the car within 3 seconds.
  6. Now start the engine and let it idle for 20 seconds.
  7. To check whether the check engine light is on or not, accelerate your car’s engine two to three times to ensure that the ignition switch timing and idle speed are within acceptable ranges.

To guarantee exact timing, it is essential to do these tasks while using a clock or a timer. If you feel any difficulty and do not know much about automobile repair, do visit the car mechanic or workshop.

In conclusion, it is important to know how to calibrate the throttle position sensor. Calibrating your throttle position sensor is a relatively easy process that can be done at home or workshop. By following the steps outlined in this article, you will be able to successfully calibrate your throttle position sensor and avoid costly replacements down the road. If you have any questions or concerns, be sure to consult a professional mechanic.
