Transaxle Range Switch

The Transaxle Range Switch is part of the Transaxle Park/Neutral Position (PNP) switch mounted on the transaxle manual shaft. The 4 inputs from the transaxle range switch indicate to the PCM which position is selected by the Transaxle selector lever. This information is used for transmission shift control, ignition timing, EVAP canister purge, EGR and IAC valve operation.




The combination of the four transaxle range input states determine the PCM commanded shift pattern. The input voltage level at the PCM is high (B+ -battery positive voltage-) when the transaxle range switch is open and low when the switch is closed to ground.
