What Does a Throttle Position Sensor Do?

The throttle position sensor (TPS) is a critical component of your vehicle's engine management system that monitors the position of the throttle valve in the throttle body. Mounted on the throttle body shaft, the TPS sends a variable voltage signal to the engine control unit (ECU) that corresponds to the throttle valve angle — from fully closed at idle to fully open at wide-open throttle. The ECU uses this real-time throttle position data to calculate the correct amount of fuel to inject, determine ignition timing, control idle speed, and manage transmission shift points. Accurate throttle position data is essential for smooth acceleration, stable idle, optimal fuel economy, and emissions control.

Why Choose Premium Standard Motor Products Throttle Position Sensors?

Premium Standard Motor Products throttle position sensors are designed to meet or exceed original equipment specifications, ensuring accurate position monitoring, reliable operation, and long service life.

Installation Notes

Professional installation is recommended for best results. TPS replacement requires disconnecting the battery, locating the sensor on the throttle body, disconnecting the electrical connector, and removing the mounting screws. Install the new sensor and align it correctly before tightening the mounting screws. Reconnect the electrical connector. The TPS may require adjustment or calibration after installation — set the throttle valve to the closed position and adjust the sensor until the correct idle voltage reading is achieved (typically 0.5V). Clear any diagnostic trouble codes and test drive to verify proper operation.
