P0C6BGenerator Position Sensor Circuit B Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0C6B tells you that circuit B of the generator resolver, the cosine winding, reads too low. In the 2023 Outlander PHEV, Mitsubishi stores it if the cosine signal is no higher than 2.000 V throughout 0.21 s; the test never pauses while the generator control unit receives 8 V or more. To confirm a repair, the matching drive cycle only asks for the power supply mode to be switched ON and a wait of five seconds or more. Likely causes are a cosine lead with a short to ground, a pinched harness near the transaxle or a failing winding. If the resolver circuit tests fine and the code returns, Mitsubishi fits a new power drive unit and, once the EV oil cooling has been checked, a new generator. P0C66 is the sine-side twin, P0C6C the high reading on the same line.
- What you may notice
- Malfunction indicator lamp right after switching on
- No charging of the drive battery by the engine
- Reduced performance in hybrid mode
- Likely causes
- LikelyCosine lead of the resolver shorted to ground
- PossiblePinched or crushed resolver harness near the transaxle
- PossibleShorted cosine winding in the generator resolver
- RareFaulty cosine input in the power drive unit
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
