P0E29Drive Motor Inverter Temperature Sensor H Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- With P0E29 the controller doubts the reading of inverter temperature sensor H although its voltage is valid. On the 2023 Outlander PHEV Mitsubishi uses it for IGBT sensor 8 of the front motor unit, the V-phase H2 position. The cold-start comparison is the same one used for sensors 1 to 7: soak of 600 s or more, IGBTs off, supply at least 8 V, test window of 1.5 s; a difference above 47 °C to either of two reference IGBT temperatures, held for 0.1 s, stores P0E29-00 and lights the MIL and the hybrid warning light. A sensor that is wrong by that much after a cold soak is offset, not overheated. The sibling for the U-phase sensor is P0E24. Mitsubishi verifies it on a test drive before installing a new power drive unit.
- What you may notice
- MIL and hybrid warning light on
- Driving usually unaffected
- Likely causes
- LikelySensor H offset against the other IGBT sensors
- PossibleMeasuring circuit in the power drive unit faulty
- RareUneven cooling of the inverter
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
