Throttle Position Sensor (TPS)

Understanding the Throttle Position Sensor

The Throttle Position Sensor (TPS) is a critical component in your vehicle's engine management system. It monitors the throttle valve's position and sends this information to the engine control module (ECM), which uses it to calculate fuel injection and ignition timing.

How the TPS Works

The TPS is typically a potentiometer or a Hall effect sensor that tracks the throttle valve's movement. As the throttle is opened or closed, the sensor sends a signal to the ECM, which adjusts engine performance accordingly.

Symptoms of a Faulty TPS

A faulty TPS can cause a range of problems, including poor engine performance, decreased fuel efficiency, and difficulty starting the engine. Some common symptoms include erratic engine behavior, hesitation or stumbling, decreased power output, and check engine light illumination.

Replacing the TPS

If you're experiencing issues with your vehicle's TPS, it's essential to have it replaced by a qualified mechanic or technician. They can diagnose the problem and install a new sensor to ensure your engine runs smoothly and efficiently.
