P2E06Gear Lever Position Sensor B Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- 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.
