P0C60: Drive Motor B Position Sensor Circuit B Range/Performance

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.

Symptoms

• Hybrid system warning with check engine lamp
• Motor B output limited
• Vibration or noise when motor B is under load

Most likely causes

• Raised contact resistance at the motor B resolver connector
• Motor B resolver stator shifted or damaged
• Interference from the high-voltage phase cables through a damaged shield

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Compare the reading with other engine data while varying the engine speed.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0C60 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• C: Subsystem depends on the code range
• 60: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0C60?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0C60?

The most common causes are: raised contact resistance at the motor B resolver connector; motor B resolver stator shifted or damaged; interference from the high-voltage phase cables through a damaged shield.
