P0E2C Drive Motor Inverter Temperature Sensor H Circuit Intermittent/Erratic

P0E2C covers an unsteady signal from inverter temperature sensor H: it flickers, jumps or drops out for moments and then recovers. That pattern differs from P0E2A and P0E2B, where the voltage stays beyond a limit. No manufacturer documents P0E2C publicly. Mitsubishi watches its sensor 8 on the 2023 Outlander PHEV only for plausibility and the two voltage limits and gives no erratic code for it. CARB's monitoring rules for hybrid input components include such intermittent faults. In practice the trigger tends to be mechanical, such as vibration at a connector, a fine crack in the sensing board or a terminal with corrosion. Freeze frame data and wiggle tests help, since the fault may be gone when the car arrives.

Likely causes

Connector contact affected by vibration
Corroded terminal in the sensor circuit
Hairline crack in the sensing board

Symptoms

  • Intermittent warning light
  • Occasional short power reductions
