P0DF9Generator Inverter Temperature Sensor C Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0DF9 is stored when the C temperature sensor of the generator inverter reports a voltage at or beyond the upper end of its window. For the Outlander PHEV Mitsubishi defines the limit as 3.75 V for 0.08 s on the W-phase high-side IGBT sensor, monitored continuously whenever the GCU has at least 8 V. An open line, a backed-out terminal in the inverter connector or a broken sensor element are the usual explanations. Unlike a real cold start, the reading does not climb as the generator works, which separates the fault from a true low temperature. Generator power may be held back until the value is valid again, and Mitsubishi fixes it by replacing the complete power drive unit. Too low a voltage on the same sensor is P0DF8; the B-sensor counterpart is P0DF6.
- What you may notice
- Engine or hybrid warning light on
- Inverter temperature stuck at a very low value
- Generator output held back
- Likely causes
- PossibleOpen signal line of sensor C
- PossibleTerminal pushed back in the inverter connector
- PossibleBroken sensor element inside the power drive unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
