What P2E02 means
P2E02 says the signal of gear lever position sensor A is stuck below the lowest value a healthy sensor can output. Typical reasons: the signal wire touches ground, the reference voltage is missing, or the sensor output has collapsed. No manufacturer publishes P2E02. The closest documented check is GM's per-axis version on the Cadillac XT4 electronic selector (19OBDG03D): X sensor 1 sets P082B, Y sensor 1 P082E, when the PWM duty cycle falls under 5 % in 3 of 4 samples at 25 ms, Type B. CARB 1968.2 (e)(15) asks for out-of-range detection on transmission inputs and keeps circuit and rationality faults under separate codes. The high counterpart is P2E03, sensor B low is P2E06. With a valid partner sensor the lever normally keeps working.
P2E02 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 P2E02
- Warning lamp and shift-system message
- Lever position shown on the display jumps or is missing
- If sensor B also fails, no range can be selected
Common causes of P2E02
- Most likelySignal wire of sensor A shorted to ground
- PossibleSensor reference voltage missing or pulled down
- PossibleSensor A output failed low
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E02 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 02 | The exact fault in that area. |
What to do next
- Note P2E02 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 P2E02
What does P2E02 mean?
P2E02 means "Gear Lever Position Sensor A Circuit Low". P2E02 says the signal of gear lever position sensor A is stuck below the lowest value a healthy sensor can output. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E02?
Drive gently and only to a workshop. With P2E02 the car can go into limp mode (reduced power) to protect itself.
Will P2E02 fail an emissions test?
P2E02 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 P2E02 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E02 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
