P0E27Drive Motor Inverter Temperature Sensor G Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0E27 marks short dropouts or jumps in the signal of inverter temperature sensor G. Between the events the reading is normal again, which is what separates it from the steady faults P0E25 and P0E26. No manufacturer documents P0E27 publicly; Mitsubishi, the one documented user of sensor G on the 2023 Outlander PHEV, checks that sensor for plausibility and for both voltage limits only. CARB expects hybrid sensor circuits to be monitored for circuit faults, which covers unstable signals as well. Likely sources are a connector with poor contact, a cracked solder joint on the sensing board or a thermistor with unstable resistance. The code can vanish before the workshop sees it, and the drive may be limited while it is active.
