What Does P082C Mean?
The gear lever X position circuit is reading high voltage. The TCM has detected that the X-axis sensor output exceeds the maximum expected threshold. This condition usually points to an open signal wire, an open ground wire to the sensor, or a sensor failure producing an abnormally high output.
Common Causes
30%
Open circuit in the gear lever X position sensor signal or ground wire
30%
Gear lever X position sensor failure with high output
20%
Disconnected or corroded sensor connector
10%
Short to voltage in the sensor signal wire
10%
TCM internal input circuit fault
Diagnostic Steps
1
Measure voltage at the gear lever X position sensor signal pin — if it reads near reference voltage (5V) regardless of lever position, suspect an open ground or failed sensor.
2
Check the ground circuit at the sensor connector for continuity back to the TCM ground pin.
3
Inspect the sensor connector for backed-out pins, corrosion, or a disconnected harness.
4
Disconnect the sensor and check if the voltage at the TCM input drops — if it does, the sensor is the fault source.
5
If the signal stays high with the sensor disconnected, trace the signal wire for shorts to voltage or open circuits.
Estimated Repair Cost

Parts + labor, varies by vehicle and location
The gear lever X position circuit is reading high voltage. The TCM has detected that the X-axis sensor output exceeds the maximum expected threshold. This condition usually points to an open signal wire, an open ground wire to the sensor, or a sensor failure producing an abnormally high output.
The most common cause of P082C (Gear Lever X Position Circuit High) is: Open circuit in the gear lever X position sensor signal or ground wire
Typical repair costs for P082C range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The TCM may lose gear position tracking, causing limp mode or preventing manual gear selection. Automatic mode may still function. Drive cautiously until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P082C to identify the root cause.
