P2E0A Gear Lever Position Sensor C Circuit Low

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

For P2E0A the module reads the signal of gear lever sensor C below the window a working sensor can occupy. On a voltage-output Hall sensor like those in Toyota's four-sensor selector patent (US10180184), this means a signal line pulled to ground, a missing feed or a sensor that has stopped driving its output. The same patent counts disconnection and short circuits as faults that can be detected continuously, and lets the remaining three sensors run a limp-home mode. No manufacturer documents P2E0A or tells what sensor C measures. CARB 1968.2 (e)(15) demands detection of out-of-range input values. The high side is P2E0B; GM's comparable per-axis low checks on its two-sensor lever are P082B and P089C, with a 5 % duty-cycle limit.

Likely causes

Signal wire of sensor C shorted to ground
Supply of sensor C missing
Sensor C output failed low

Symptoms

  • Warning lamp or shift message
  • Limp-home on the remaining sensors
  • No noticeable change while other sensors are valid
