P0DF3Generator Inverter Temperature Sensor C Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0DF3 is logged when sensor C in the generator inverter delivers an unsteady signal: short spikes, gaps or values that change faster than the module temperature ever could. Such faults often start at connectors that loosen under engine vibration and repeated heating cycles, or at pins attacked by moisture. No manufacturer documents P0DF3 publicly, and Mitsubishi, which does monitor a W-phase sensor in its generator unit, defines no intermittent code for it. CARB requires these thermal inputs to be monitored nonetheless. The warning may vanish after a restart and return days later, so it pays to note when and under which load it appeared. Constant faults of the same sensor are P0DF2, P0DF8 and P0DF9; the matching fault on sensor B is P0DF1.
- What you may notice
- Warning light that appears only now and then
- Brief drops in generator power
- Code stored as history fault without current symptoms
- Likely causes
- LikelyTerminal losing contact under vibration or heat cycles
- PossibleMoisture or corrosion in the inverter connector
- RareIntermittent connection inside the inverter module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
