Transmission Position Switch/Sensor: Description and Operation
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+) when the transaxle range switch is open and low when the switch is closed to ground. The state of each input is available for display on the
scan tool. The four parameters represent transaxle range switch Parity, A, B, and C inputs respectively. Refer to the Transaxle Range Switch Valid
Combinations Table in DTC P0705 Trans Range Switch Circuit.
