Transmission Position Sensor/Switch: Description and Operation

COMPONENT DESCRIPTION




Inhibitor switch
Detects the selector lever position and sends a signal to the A/T control unit.




Park/Neutral Position Switch
When the gear position is "P" or "N", park/neutral position switch is "ON". The A/T control unit detects the position because the continuity of the line (the "ON" signal) exists. The A/T control unit sends the park/neutral signal to the ECM.
