P0DF0Generator Inverter Temperature Sensor B Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0DF0 is the catch-all circuit code for temperature sensor B in the generator inverter, the power stage that drives the generator of a two-machine hybrid. The controller sets it when the sensor line is electrically faulty but the fault is not sorted into low, high or erratic. No manufacturer documents P0DF0 publicly. Mitsubishi fits one thermistor per IGBT in the generator unit of the Outlander PHEV and reports the second high-side sensor (V phase) only through P0DF4 to P0DF6, never through this general code; Ford likewise names only open and short checks for its generator inverter sensor. CARB requires every input that feeds inverter thermal management to be checked for circuit faults. Without a valid value the controller has to assume the worst and usually limits generator output.
- What you may notice
- Hybrid or engine warning light on
- Reduced generator output, weaker charging while driving
- Hybrid system may switch to a restricted mode
- Likely causes
- PossibleLoose, corroded or damaged connector at the inverter or power unit
- PossibleThermistor or its signal path inside the inverter module faulty
- RareFaulty evaluation input in the generator control unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
