P0C64Generator Position Sensor Circuit A
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0C64 is the catch-all entry for the first pickup circuit of the generator resolver, the sensor that reports rotor angle so the inverter can energise the generator phases at the right moment. It is used when the controller judges that circuit faulty without sorting the fault into low, high, implausible or sporadic. No manufacturer documents P0C64 publicly. Mitsubishi shows how such faults get split on the 2023 Outlander PHEV: the sine winding, which it treats as circuit A, has its own low and high codes (P0C66, P0C67), and a failed internal status goes to P0A4B. CARB asks for an approved generator monitoring plan and for circuit and range checks on hybrid inputs. Expect a hybrid system warning and, depending on the design, reduced power or no charging by the engine.
- What you may notice
- Hybrid system or malfunction indicator lamp on
- Engine runs but the high-voltage battery is no longer charged by the generator
- Reduced power or hybrid functions disabled
- Likely causes
- LikelyOpen, chafed or shorted lead in the first resolver pickup winding circuit
- PossibleCorroded or loose resolver connector between generator and inverter
- PossibleDamaged pickup winding inside the generator resolver stator
- RareFault in the generator control electronics of the inverter or power drive unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
