What P2E06 means
The signal of sensor B, the redundant gear lever sensor, has dropped under its permitted minimum. Electrically that points to a short to ground in its signal line, a dead sensor or a missing feed on its own supply branch. P2E06 is not published by any manufacturer. GM catches the same condition per axis on the XT4 selector as P089C (X) and P08A1 (Y), each when the PWM duty cycle of sensor 2 stays below 5 % for three failures in four samples; Type B with a two-trip MIL. Because sensor A still delivers a full position, the driver usually notices only the warning; GM's patent lets the module carry on with the remaining valid signal. Sensor A low is P2E02, sensor B high P2E07. CARB 1968.2 (e)(15) requires such out-of-range checks.
P2E06 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E06
- Warning lamp after two trips
- Selector keeps working on sensor A
- Range selection lost if sensor A fails as well
Common causes of P2E06
- Most likelySignal line of sensor B shorted to ground
- PossibleSupply branch of sensor B dead
- PossibleSensor B output stuck low
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E06 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 06 | The exact fault in that area. |
What to do next
- Note P2E06 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 P2E06
What does P2E06 mean?
P2E06 means "Gear Lever Position Sensor B Circuit Low". The signal of sensor B, the redundant gear lever sensor, has dropped under its permitted minimum. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E06?
Drive gently and only to a workshop. With P2E06 the car can go into limp mode (reduced power) to protect itself.
Will P2E06 fail an emissions test?
P2E06 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 P2E06 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E06 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
