Intermittent fault
- Ignition off.
Check that the gear-shift position sensor is securely mounted.
Check control module and transmission connectors and gear-shift position sensor ground terminal for intermittent loose connections (terminals) according to Loose connections (terminals) and contact resistance and oxidation according to Contact resistance and oxidation .
Check cables between the gear-shift position sensor and transmission control module (TCM) for an intermittent open-circuit according to Open-circuit, intermittent faults , an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults and an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults .
Remedy as necessary.
