P0DF1Generator Inverter Temperature Sensor B 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
- P0DF1 means the signal of generator inverter temperature sensor B drops out or jumps for short moments and then looks normal again. Typical triggers are temperature steps faster than the power module could physically heat or cool, or brief readings that resemble an open line. No manufacturer documents P0DF1 publicly: Ford's monitors for its generator inverter sensor cover only opens and shorts (P0BCE, P0BCF), and Mitsubishi has no intermittent code for the corresponding V-phase sensor at all. CARB still expects inverter thermal inputs to be monitored. Because the fault comes and goes, freeze frame data and a wiggle test of the inverter harness tell more than swapping parts. A steady fault on this sensor would be logged as P0DF0, P0DF5 or P0DF6 instead.
- What you may notice
- Warning light that comes and goes
- Occasional short loss of generator power
- Fault often not reproducible at the workshop
- Likely causes
- LikelyLoose or fretted terminal in the inverter connector
- PossibleHarness chafing or vibration damage near the power unit
- RareIntermittent contact inside the inverter module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €80 – €4,000
