What P0C19 means
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.
P0C19 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0C19
- 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
Common causes of P0C19
- Most 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
- Less likelyInternal fault of the inverter power stage or motor winding
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C19 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| 19 | The exact fault in that area. |
What to do next
- Note P0C19 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0C19
What does P0C19 mean?
P0C19 means "Drive Motor A Torque Delivered Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C19?
Drive gently and only to a workshop. With P0C19 the car can go into limp mode (reduced power) to protect itself.
Will P0C19 fail an emissions test?
Yes, it can. P0C19 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0C19 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 8 hours of work. This is a job for a workshop.
Will P0C19 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
