What P0C00 means
P0C00 reports that the current of drive motor A is lower than the controller expects for the commanded torque, the counterpart of P0C01 (current high). No manufacturer documents this exact code publicly; GM and Stellantis use only P0C01 from this group. CARB requires hybrids to monitor electric motor performance. Too little current points to a high-resistance three-phase joint, an open winding path or an inverter that cannot drive the phases. GM checks a missing phase separately as P0C05. The driver usually notices weak electric drive and a warning lamp; the vehicle may switch to engine-only or limp mode.
P0C00 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0C00
- Weak or missing electric drive torque
- Malfunction indicator lamp or hybrid system warning
- Vehicle runs on the engine only or in limp mode
Common causes of P0C00
- PossibleHigh-resistance or loose three-phase connection at motor A or the inverter
- PossibleInverter power stage for motor A not delivering current
- Less likelyOpen or damaged winding in drive motor A
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C00 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. |
| 00 | The exact fault in that area. |
What to do next
- Note P0C00 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 P0C00
What does P0C00 mean?
P0C00 means "Drive Motor A Current Low". P0C00 reports that the current of drive motor A is lower than the controller expects for the commanded torque, the counterpart of P0C01 (current high). It is a generic code, so it means the same on every make.
Is it safe to drive with P0C00?
Drive gently and only to a workshop. With P0C00 the car can go into limp mode (reduced power) to protect itself.
Will P0C00 fail an emissions test?
Yes, it can. P0C00 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 P0C00 to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0C00 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
