Throttle Position Sensor: Description and Operation

CIRCUIT OPERATION
From the Powertrain Control Module (PCM), circuit K6 supplies 5 volts to the Throttle Position Sensor (TPS). Circuit K6 connects to cavity A17 of the PCM.

Circuit K22 delivers the TPS signal to the PCM. Circuit K22 connects to cavity A23 of the PCM.

The PCM provides a ground for the TPS signal (circuit K22) through circuit K4. Circuit K4 connects to cavity A4 of the PCM.
