Transmission Position Switch/Sensor: 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 Torque Converter Clutch (TCC) operation. Do not drive vehicle with park/neutral switch disconnected, as idle quality may be
affected.
