Transmission Position Sensor/Switch: Description and Operation

[1][2]PARK/NEUTRAL POSITION SWITCH
The automatic transaxle manual valve lever position sensor supplies the park/neutral input to the Powertrain Control Module. The [1][2]park/neutral switch input tells the PCM whether the transmission is in Park, Neutral, or a drive gear selection. This input effects idle speed, fuel injector pulse width and ignition timing.
