What P2C6C means
P2C6C is the umbrella code for the current in phase Y of drive motor A, the middle phase of the second X/Y/Z winding set. No manufacturer documents it publicly. Ford's 2019 hybrid summary explains what such phase current codes collect: the inverter is watched for overcurrent, current sensor faults and current regulation faults, and the result is stored per phase. For Y that means the measured current does not follow the command, or the reading cannot be trusted, without being clearly low (P2C6D) or high (P2C6E). A failed sensor circuit has its own code, P2E1F. CARB leaves the drive motor monitoring plan to each manufacturer, so thresholds differ. In practice look at the Y phase lead, its terminals and the inverter, and expect a warning and reduced or no electric drive.
P2C6C at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1.5 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C6C
- Hybrid or drive warning, MIL on
- Reduced electric torque or jerky drive
- Vehicle not ready to drive in severe cases
Common causes of P2C6C
- Most likelyInverter cannot regulate the phase Y current to its command (control or gate drive fault)
- PossibleLoose, corroded or overheated phase Y terminal at inverter or motor
- PossiblePhase Y current reading implausible against the other two phases
- Less likelyPartial winding fault in phase Y of the motor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C6C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 6C | The exact fault in that area. |
What to do next
- Note P2C6C 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 P2C6C
What does P2C6C mean?
P2C6C means "Drive Motor A Phase Y Current". P2C6C is the umbrella code for the current in phase Y of drive motor A, the middle phase of the second X/Y/Z winding set. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C6C?
Drive gently and only to a workshop. With P2C6C the car can go into limp mode (reduced power) to protect itself.
Will P2C6C fail an emissions test?
Yes, it can. P2C6C 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 P2C6C to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 8 hours of work. This is a job for a workshop.
Will P2C6C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
