Description:
The Throttle Position Sensor, also known as the TPS, measures the angle of the throttle plate as the vehicles driver presses on the accelerator pedal and sends a voltage signal to the Engine Control Module (ECM). The ECM interprets the voltage signal and commands the fuel, transmission and ignition systems based on the Throttle Position Sensor's signal. A malfunctioning or inoperative Throttle Position Sensor can cause drivability symptoms such as a no start condition, hesitation, stalling and surging conditions. It can also cause the Check Engine Light (CEL), Service Engine Soon (SES) or Malfunction Indicator Lamp (MIL) to illuminate and can set a trouble code (P-code) in the ECM when not functioning correctly.
