Transmission Position Sensor/Switch: Description and Operation

The transaxle range switch is located on the automatic transaxle. The Powertrain Control Module (PCM) detects the transaxle range by monitoring the ON and OFF signals from the transaxle range switch. The PCM uses the transaxle range switch signal as one of the inputs in order to control the fuel injectors, the Idle Air Control (IAC) valve, and the automatic transaxle performance.
