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.

Symptoms

• Intermittent warning light
• Occasional short power reductions

Most likely causes

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

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Gently move the wiring with the engine running and watch whether the reading changes.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0E2C means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• E: Subsystem depends on the code range
• 2C: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0E2C?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0E2C?

The most common causes are: connector contact affected by vibration; corroded terminal in the sensor circuit; hairline crack in the sensing board.
