P0C60Drive Motor B 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
- P0C60 indicates that the second winding of the motor B resolver (Circuit B) is electrically intact but delivers values the controller rejects as unrealistic, for example an amplitude that no longer agrees with the first winding or an angle that jumps against the measured speed. No manufacturer documents this code publicly. The idea behind it is the separate rationality test that CARB demands for input sensors, apart from circuit and range checks. Practical suspects are contact resistance at the plug, a resolver stator that has moved or been damaged, and stray coupling from the high-voltage phase cables onto a poorly shielded line. P0C61 to P0C63 cover low, high and sporadic Circuit B faults, P0A46 the combined signal.
- What you may notice
- Hybrid system warning with check engine lamp
- Motor B output limited
- Vibration or noise when motor B is under load
- Likely causes
- LikelyRaised contact resistance at the motor B resolver connector
- PossibleMotor B resolver stator shifted or damaged
- RareInterference from the high-voltage phase cables through a damaged shield
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
