P2E08 Gear Lever Position Sensor C Circuit

Drive cycleNot required
Limp modePossible

A third gear lever position sensor, C, only exists on selectors with more than the usual redundant pair. Toyota's patent US10180184 shows such a design: four Hall sensors in a row face a magnet in the shift lever, the voltages they produce encode the position, and if any one of them is faulty the other three still allow limp-home driving. Which job the letter C has in a given vehicle is not published; no manufacturer documents P2E08 or any other sensor C code. P2E08 is the general circuit fault of that sensor – open wiring, missing supply or an unreadable signal – before any low/high split (P2E0A, P2E0B). CARB 1968.2 (e)(15) requires the module to detect circuit faults of such transmission inputs. GM's lever tables only know sensors 1 and 2.

Likely causes

Connector or wiring at the selector assembly faulty
Sensor C inside the selector failed
Evaluating module input faulty

Symptoms

  • Warning lamp or shift-system message
  • Shifting continues on the remaining sensors
  • A further sensor fault may force neutral
