Silhouette V6-3.4L VIN E (1996)
Transmission Position Switch/Sensor: Description and Operation
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+) when the transaxle range switch is open and low when the switch is
closed to ground. The state of each input is represented on the scan tool as X=high voltage level, 0=10w voltage level. The four parameters represent
transaxle range switch Parity, A, B, and C inputs respectively. Refer to Transaxle Range Switch Valid Combinations Table.
