Transmission Position Sensor/Switch: Testing and Inspection

Description:




Transaxle Range Switch Valid Input Combinations:






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 High voltage level, Low voltage level. The four parameters represent transaxle range switch Parity, A, B, and C inputs respectively. Valid transaxle range input combinations are shown in the Transaxle Range Switch Valid Input Combinations table. For DTC diagnosis refer to System Diagnosis / Diagnostic Tables / Diagnostic Trouble Code Tables. Testing and Inspection
