What P0C6C means
P0C6C is the high-side fault of circuit B in the generator resolver. On the 2023 Outlander PHEV, where circuit B is the cosine winding, Mitsubishi triggers it when the cosine voltage sits at 4.900 V or above for 0.21 s; the monitor stays active as long as the generator control unit is supplied with 8 V. First rule out a cosine lead that touches a voltage source, followed by connector damage and an internal fault in the power drive unit, which houses the generator control unit. Mitsubishi also has the radiator fan codes dealt with first and, before fitting a new generator, the EV oil cooling inspected. Unlike P0C6D, the voltage here is held out of range rather than leaving it briefly. P0C67 is the same fault on the sine side.
P0C6C at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 10 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0C6C
- Malfunction indicator lamp and hybrid warning
- Generator inactive, state of charge drops while driving
- Engine may run more often or the car limits power
Common causes of P0C6C
- Most likelyCosine lead shorted to a supply or excitation line
- PossibleDamaged resolver connector with bridged pins
- PossibleInternal fault in the power drive unit holding the generator control unit
- Less likelyOpen cosine lead that drifts high at the input
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C6C 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. |
| 6C | The exact fault in that area. |
What to do next
- Note P0C6C 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 P0C6C
What does P0C6C mean?
P0C6C means "Generator Position Sensor Circuit B High". P0C6C is the high-side fault of circuit B in the generator resolver. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C6C?
Drive gently and only to a workshop. With P0C6C the car can go into limp mode (reduced power) to protect itself.
Will P0C6C fail an emissions test?
Yes, it can. P0C6C 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 P0C6C to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P0C6C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
