Checking The Park/Neutral Position (PNP) Function In The Gear-Shift Position Sensor: Notes

NOTE: The test assumes that the battery is fault free, that the starter motor circuit has been checked and that no relevant diagnostic trouble codes (DTCs) for the symptom are stored.

CAUTION: Avoid touching the pins in the control module and the corresponding connector on the cable harness. There is a risk of static discharge which could damage the control module. Discharge yourself and tools to be used by holding the tool's metal part and touching a body part on the car just before starting to work.

Move the gear selector to position P or N. Parking brake applied.
Check the voltage between central electronic module (CEM) terminals #D9 and #E1.

The voltage must be approximately 0 V.
