P0C6AGenerator Position Sensor Circuit B 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
- P0C6A concerns circuit B of the generator resolver, the cosine side at Mitsubishi: its signal stays inside the electrical limits but does not agree with what the controller expects. Because sine and cosine together describe one angle, a cosine trace with the wrong amplitude or a drifting centre shows up as a mismatch against circuit A, even though no line is shorted. Possible reasons are a loose or twisted sensor stator, a winding with partial damage, or noise picked up from nearby phase leads. No manufacturer documents P0C6A publicly; Mitsubishi's comparable window check on the 2023 Outlander PHEV (2.1 to 2.9 V, 0.28 s) is stored as P0A4C. Hard low or high readings on this circuit belong to P0C6B and P0C6C; the circuit A version is P0C65.
- What you may notice
- Hybrid warning lamp
- Generator used only partly or not at all
- Unusual noise or vibration from the transaxle under load
- Likely causes
- PossibleLoose or twisted resolver stator changing the cosine amplitude
- PossiblePartially shorted cosine winding with weakened output
- PossibleNoise from phase leads due to damaged shielding or poor routing
- RareHigh contact resistance in the circuit B connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
