A throttle position sensor reset tool is a small hand-held device that is used to reset the throttle position sensor in a vehicle. This sensor is responsible for sending information to the engine control unit about the position of the throttle. If this sensor is not functioning properly it can cause the engine to run rough or stall.

How does a TPS work?
It picks up air from the intake, passes it through the mass airflow sensor and into the throttle body. While there, the TPS will continually measure the amount of air. The engine then uses that data, alongside other values like RPM, air temp., and mass air flow in determining how much fuel to inject.
