Neon L4-2.0L SOHC (1995)
Transmission Position Switch/Sensor: Description and Operation
Fig. 14 Park/Neutral Switch
PURPOSE
The switch provides an input to the PCM to indicate whether the automatic transaxle is in Park/Neutral, or a drive gear selection. This input is
used to determine idle speed (varying with gear selection), and ignition timing advance.
The park/neutral input is also used to cancel vehicle speed control.
The park/neutral position switch is located on the automatic transaxle housing (Fig. 14). Manual transaxles do not use park/neutral switches.
CIRCUIT OPERATION
When closed, the PARK/NEUTRAL position switch provides a ground path on circuit T41 for the coil side of the starter motor relay. The
case-grounded switch provides ground for circuit T41.
Circuit A41 from the ignition switch provides battery voltage to the coil side of the relay Circuit T41 connects to cavity 2 of the
PARK/NEUTRAL position switch connector.
Circuit T41 splices to cavity 50 of the Powertrain Control Module (PCM). The PARK/NEUTRAL position switch provides an input to the PCM.
NOTE: The park/neutral switch is sometimes referred to as the neutral safety switch.
