P0C19Drive Motor A Torque Delivered 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
- P0C19 is a plausibility check: the torque that motor A actually delivers, calculated by the motor control processor, does not follow the slewed torque command. GM sets it when the difference exceeds 123 Nm for 0.1875 s within 0.2 s on the 2016 and 2018 tables, Type A, one trip; eAssist uses 36 Nm as Type B, two trips. The 2012 two-mode trucks check whether the sum of the three phase currents exceeds 110 A for 200 ms. Stellantis lists P0C19 on the Jeep Wrangler 4xe and the Wagoneer PHEV with P1B03, a resolver rationality fault, and cures it by reflashing the power inverter module. The electric drive shuts down and the engine takes over.
- What you may notice
- Malfunction indicator lamp
- Electric drive shuts off and the engine takes over
- Engine stop-start no longer works or a service hybrid system warning appears
- Likely causes
- LikelyOutdated power inverter module software (Stellantis 08-059-25, 08-231-24)
- PossibleImplausible rotor position signal from the motor A resolver or its wiring
- PossibleFaulty phase current sensing distorting the calculated torque
- RareInternal fault of the inverter power stage or motor winding
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
