What P0C67 means
With P0C67 the controller sees circuit A of the generator resolver stuck above its upper limit. On the 2023 Outlander PHEV Mitsubishi assigns it to the sine winding and trips it once that voltage stays at or above 4.900 V for 0.21 s; the check runs continuously while the generator control unit has 8 V or more. Note the uneven window, since the lower limit is 2.0 V. A lead shorted to a supply potential is the textbook cause, and depending on the input stage an open line can also float high. The Bosch patent on resolver short detection separates both short types by the averaged line potential. Mitsubishi's repair path matches P0C66 and ends with a new power drive unit or generator. P0C6C is the matching cosine code.
P0C67 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 P0C67
- Malfunction indicator lamp and hybrid warning
- Engine-driven charging stops, battery charge falls faster
- Power limitation or hybrid functions switched off
Common causes of P0C67
- Most likelySine lead of the resolver shorted to a supply or excitation potential
- PossibleOpen sine lead that floats high at the input stage
- PossibleFaulty resolver input in the power drive unit
- Less likelyInsulation fault between windings inside the resolver
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C67 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. |
| 67 | The exact fault in that area. |
What to do next
- Note P0C67 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 P0C67
What does P0C67 mean?
P0C67 means "Generator Position Sensor Circuit A High". With P0C67 the controller sees circuit A of the generator resolver stuck above its upper limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C67?
Drive gently and only to a workshop. With P0C67 the car can go into limp mode (reduced power) to protect itself.
Will P0C67 fail an emissions test?
Yes, it can. P0C67 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 P0C67 to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P0C67 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
