Transmission Position Sensor/Switch: Description and Operation
The
park/neutral switch indicates to the ECM when the transmission is in park or neutral. This information is used by the ECM for ignition timing, IAC operation and transmission Torque Converter Clutch (TCC) operation. Do not drive vehicle with park/neutral switch disconnected, as idle quality may be affected.
