P0C65Generator Position Sensor Circuit A Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0C65 flags circuit A of the generator resolver as electrically present but not believable. The trace stays between the hard low and high limits, yet its amplitude, centre voltage or relation to the second winding no longer fits the rotor angle the controller expects, for example after the sensor stator has shifted or when the phase cables couple noise into it. No manufacturer documents P0C65 publicly. Mitsubishi runs an analogous window test on the 2023 Outlander PHEV: a sine or cosine level outside 2.1 to 2.9 V for 0.28 s counts as a plausibility fault, but it is filed under P0A4C for the whole sensor. P0C66 and P0C67 cover hard low and high readings on the same circuit. Typical consequences are a hybrid warning and limited use of the generator.
- What you may notice
- Hybrid system warning light
- Generator use restricted, less charging while driving
- Occasional roughness when the engine starts or stops in hybrid mode
- Likely causes
- PossibleResolver stator loose or shifted, for instance after work on the generator or transaxle
- PossibleInterference from the phase cables because of a misrouted or damaged resolver harness
- PossiblePartially damaged winding that weakens the circuit A signal
- RareGenerator control software that misjudges a sound signal
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
