P2E02Gear Lever Position Sensor A Circuit Low

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Can trigger limp mode
How the car detects it
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.
What you may notice
  • 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
Likely causes
  • LikelySignal wire of sensor A shorted to ground
  • PossibleSensor reference voltage missing or pulled down
  • PossibleSensor A output failed low
