Where it lives

For P0820, the circuit described runs through the sensor. The description of P0820 reports a fault at the sensor.

Check these first

• An open or short in the gear lever X-Y position sensor circuit
• A faulty gear lever X-Y position sensor
• Corrosion at the X-Y sensor connector
• A faulty gear lever or linkage
• A TCM or PCM fault

What to do next

1. Read the gear lever X-Y position on a scan tool
2. Test the X-Y sensor circuit for an open or short
3. Check the X-Y sensor connector and linkage
4. Check the gear lever movement
5. Replace the sensor if the circuit tests good
