Replacing the Throttle Position Sensor (TPS)

The throttle position sensor, or TPS, is a critical component of any automobile. It is responsible for monitoring the throttle’s position and providing information to the engine control unit (ECU). In order to maintain optimal performance, it is important to replace the throttle position sensor when it fails.

Once you have located it, you will need to disconnect any electrical connections before removing the old TPS. This can usually be done with a flathead screwdriver or a pair of pliers.

Once you have removed the old TPS, you will need to install the new one. Make sure that you follow all instructions that come with the new part and connect all electrical connections tightly before securing it in place. After everything is connected properly, you can move onto testing and adjusting your new TPS.

Replacing the Idle Air Control (IAC) Valve
