What P082A means
Gear lever X and Y position sensors detect a selector's position in two directions: on an H-gate shift and select direction (a LuK patent uses two sensors about 90° apart), on a shift-by-wire lever its two axes. P0820 covers the whole X-Y circuit, P0821–P0824 and P082A–P082F sensor 1, P089A–P08A3 a redundant sensor 2. GM uses P082A–P082F on its electronic range selector (2019 tables, Cadillac XT4, 2025): a Hall sensor delivers a PWM signal, measured as duty cycle. P082A sets when the measured X position lies outside the lever's path (5.5 % duty cycle equals about 100 N of side force), the PWM signal has a frequency error, or X sensors 1 and 2 differ by more than 12 %; 3 of 4 samples in 2019, 10 of 12 in 2025 with an added angle check. Type B, MIL after two trips; the other sensor takes over.
P082A at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P082A
- Check engine lamp after two trips (GM)
- 'Shift to park' message or transmission warning
- Range selection restricted; with both sensors failed the vehicle goes to park
Common causes of P082A
- Most likelySelector assembly faulty (Hall sensor, magnet, worn mechanism)
- PossibleConnector or wire with resistance or interference (frequency error)
- PossibleLever mechanically blocked (object in the console)
- Less likelyEngine or selector module software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P082A means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| 2A | The exact fault in that area. |
What to do next
- Note P082A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P082A
What does P082A mean?
P082A means "Gear Lever X Position Sensor 1 Circuit Range/Performance". Gear lever X and Y position sensors detect a selector's position in two directions: on an H-gate shift and select direction (a LuK patent uses two sensors about 90° apart), on a shift-by-wire lever its two axes. It is a generic code, so it means the same on every make.
Is it safe to drive with P082A?
Drive gently and only to a workshop. With P082A the car can go into limp mode (reduced power) to protect itself.
Will P082A fail an emissions test?
P082A is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P082A to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P082A clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
