P0C00Drive Motor A Current Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Weak or missing electric drive torque
- Malfunction indicator lamp or hybrid system warning
- Vehicle runs on the engine only or in limp mode
- Likely causes
- PossibleHigh-resistance or loose three-phase connection at motor A or the inverter
- PossibleInverter power stage for motor A not delivering current
- RareOpen or damaged winding in drive motor A
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
