Throttle Position Sensor: Description and Operation

CIRCUIT OPERATION
From the Powertrain Control Module (PCM), circuit K6/K7 supplies 5 Volts to the Throttle Position Sensor (TPS). Circuit K7 connects to cavity 17 of the PCM connector.

Circuit K22 delivers the TPS signal to the PCM. Circuit K22 connects to cavity 23 of the PCM connector.

The PCM provides a ground path for the TPS signal (circuit K22) through circuit K4. Circuit K4 connects to cavity 4 of the PCM connector.
