P2E09 Gear Lever Position Sensor C Range/Performance

Check engine lightOn
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

P2E09 means sensor C produces an electrically valid signal that contradicts the lever position given by the other sensors. No manufacturer documents this code or names the role of a sensor C, so the logic can only be inferred from the component. In Toyota's four-Hall-sensor selector patent (US10180184) a sensor counts as abnormal when the difference between its voltage and those of its neighbours leaves a preset tolerance. The patent also explains a weak spot: a sensor frozen at a mid value is hard to spot until the driver moves the lever to a particular position. CARB 1968.2 (e)(15) asks for such rationality checks on transmission inputs under a code separate from circuit faults. Sensors A and B have the same check as P2E01 and P2E05, which Lexus and GM use.

Likely causes

Sensor C output frozen at an intermediate value
Magnet or lever mechanism worn or displaced
Plausibility logic of the selector software too strict

Symptoms

  • Warning appears only after certain lever movements
  • Range display briefly disagrees with lever position
  • Limp-home with restricted selection possible
