P0917
Gear Shift Position Circuit High
- Severity
- High
- Driving
- Drive only to a garage
The gear shift position signal is stuck high - typically shorted to voltage or a lost earth. The module cannot confirm whether a gear is engaged, so it will refuse to complete a shift and will usually leave the car in neutral.
Possible causes
- CommonWiring shorted to voltage or a lost earth between the sensor and the module
- CommonCorroded or water-ingressed connector at the gearbox
- CommonFailed sensor
- PossibleLoss of the reference voltage or the sensor earth
- PossibleChafed harness at the gearbox
What you might notice
- Car stuck in neutral or will not move
- Gear changes refused
- Gear display blank
- Transmission warning message
- Check engine light on
What to check, in order
- Unplug the sensor and check whether the high reading persists at the harness.
- Check the reference voltage and earth before condemning the sensor.
- Inspect the connector for corrosion and water.
- Look for other codes sharing the same reference circuit.
- Run the position calibration after any repair.
