Neutral Safety Switch: Description and Operation
PURPOSE
Signals the Powertrain Control Module (PCM) of gear selection.
OPERATION
On vehicles equipped with automatic transmissions, the park/neutral switch indicates if the transmission is in NEUTRAL, PARK, or a DRIVE
GEAR. Based on input from this switch the PCM will adjust fuel injector pulse width, ignition timing advance, and idle speed.
CIRCUIT OPERATION
When closed, the PARK/NEUTRAL position switch provides an input to the Powertrain Control Module (PCM) on circuit T41. The T41 circuit is
spliced and provides a ground path for the engine starter relay, and an input to the Transmission Control Module (TCM).
