What P2CC6 means
P2CC6 means supply B of the generator inverter is present but below its permitted level. A weak gate driver feed is dangerous for the power stage: transistors that are not driven fully on run in a lossy partial state and heat up quickly, so the inverter typically blocks the generator. No manufacturer documents P2CC6 publicly. Ford's summary for its 2019 power-split hybrids places the related supply A code P0E10 among the generator-side gate signal faults together with P0BCE and P0BCF, which suggests the same home for supply B. Causes range from a failing internal regulator to low 12 V input during start-up or a corroded ground. CARB requires circuit monitoring for hybrid parts. Siblings: P2CC5 (open) and P2CC7 (high).
P2CC6 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2CC6
- Hybrid system warning light and MIL on
- Generator limited or switched off, reduced hybrid performance
Common causes of P2CC6
- PossibleInternal regulator of supply B delivering too little voltage
- PossibleLow 12 V input to the inverter, e.g. weak auxiliary battery
- Less likelyCorroded ground or connector of the inverter
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2CC6 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. |
| C6 | The exact fault in that area. |
What to do next
- Note P2CC6 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 P2CC6
What does P2CC6 mean?
P2CC6 means "Generator Inverter Power Supply B Circuit Low". P2CC6 means supply B of the generator inverter is present but below its permitted level. It is a generic code, so it means the same on every make.
Is it safe to drive with P2CC6?
Drive gently and only to a workshop. With P2CC6 the car can go into limp mode (reduced power) to protect itself.
Will P2CC6 fail an emissions test?
Yes, it can. P2CC6 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 P2CC6 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2CC6 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
