P2E03Gear Lever Position Sensor A Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- With P2E03 the module sees the signal of sensor A above the highest value the sensor can legitimately send. On a pulled-up input this happens when the signal wire is open; it also follows a short to the supply or a lost sensor ground. No manufacturer publishes P2E03. GM checks the same kind of fault axis by axis on the XT4 selector: P082C and P082F set when the duty cycle of X or Y sensor 1 rises above 95 % (19OBDG03D, 3 of 4 samples, Type B, MIL after two trips). GM's patent explains the consequence: a coordinate that fails makes that sensor's whole position signal invalid, and the module relies on the second sensor. P2E02 is the low side, P2E07 the same high fault on sensor B. CARB 1968.2 (e)(15) requires this two-sided check.
