Throttle Position Sensor
The
TCM uses the
Throttle Position Sensor (TPS) signal to determine shift points. The TPS circuit is hard wired to the TCM. If Pcode P0122 "Throttle Position Sensor circuit" is present, there may be a TPS code stored in the
PCM. Always repair the PCM throttle position sensor DTC's first.
