P082B
Gear Lever X Position Sensor 1 Circuit Low
Transmission / shift controls
Generic OBD-II
Medium
What it means
P082B means the transmission controller sees an abnormally low voltage from the gear-lever (shift selector) X-axis position sensor. The controller relies on this sensor to know which way you've moved the selector, so a bad signal can lead to harsh or wrong-gear shifts. The engine still starts and runs — this is an electrical fault in the shift-position sensing circuit, not a mechanical failure.
Medium
Can I keep driving? Usually driveable, but expect harsh or unexpected shifts and a possible limp mode until it's repaired.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh or unexpected shift shock
- Erratic or delayed gear selection
- Transmission may drop into limp (fail-safe) mode
Common causes
Most likely first
- Short-to-ground or low-voltage fault in the gear-lever position sensor wiringLikely
- Failed gear-lever X position sensorCommon
- Loose or corroded connector at the sensorCommon
- Faulty transmission control module (less common)Less often
How to diagnose & fix
Work through it in order
- Scan for freeze-frame data and any companion codes (P082A, P082C) to confirm the circuit.
- Inspect the sensor connector and harness for chafing, damage, or corrosion.
- Measure the sensor's signal voltage against spec; a reading stuck low points to a short or a dead sensor.
- Repair the wiring or replace the gear-lever position sensor as needed.
- Clear the code and road-test; if it returns with known-good wiring, suspect the TCM.
FAQ
Quick answers
Is it safe to drive with P082B?+
For short trips usually yes, but shifting may be harsh or the transmission may enter limp mode. Repair it promptly to avoid getting stranded in a fail-safe gear.
Can I just clear P082B?+
It will clear, but the code returns as soon as the sensor circuit is read again until the wiring or sensor is fixed.
