What P0C6A means
P0C6A concerns circuit B of the generator resolver, the cosine side at Mitsubishi: its signal stays inside the electrical limits but does not agree with what the controller expects. Because sine and cosine together describe one angle, a cosine trace with the wrong amplitude or a drifting centre shows up as a mismatch against circuit A, even though no line is shorted. Possible reasons are a loose or twisted sensor stator, a winding with partial damage, or noise picked up from nearby phase leads. No manufacturer documents P0C6A publicly; Mitsubishi's comparable window check on the 2023 Outlander PHEV (2.1 to 2.9 V, 0.28 s) is stored as P0A4C. Hard low or high readings on this circuit belong to P0C6B and P0C6C; the circuit A version is P0C65.
P0C6A 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 P0C6A
- Hybrid warning lamp
- Generator used only partly or not at all
- Unusual noise or vibration from the transaxle under load
Common causes of P0C6A
- PossibleLoose or twisted resolver stator changing the cosine amplitude
- PossiblePartially shorted cosine winding with weakened output
- PossibleNoise from phase leads due to damaged shielding or poor routing
- Less likelyHigh contact resistance in the circuit B connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C6A 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. |
| 6A | The exact fault in that area. |
What to do next
- Note P0C6A 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 P0C6A
What does P0C6A mean?
P0C6A means "Generator Position Sensor Circuit B Range/Performance". P0C6A concerns circuit B of the generator resolver, the cosine side at Mitsubishi: its signal stays inside the electrical limits but does not agree with what the controller expects. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C6A?
Drive gently and only to a workshop. With P0C6A the car can go into limp mode (reduced power) to protect itself.
Will P0C6A fail an emissions test?
Yes, it can. P0C6A 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 P0C6A to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P0C6A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
