What P0C6B means
P0C6B tells you that circuit B of the generator resolver, the cosine winding, reads too low. In the 2023 Outlander PHEV, Mitsubishi stores it if the cosine signal is no higher than 2.000 V throughout 0.21 s; the test never pauses while the generator control unit receives 8 V or more. To confirm a repair, the matching drive cycle only asks for the power supply mode to be switched ON and a wait of five seconds or more. Likely causes are a cosine lead with a short to ground, a pinched harness near the transaxle or a failing winding. If the resolver circuit tests fine and the code returns, Mitsubishi fits a new power drive unit and, once the EV oil cooling has been checked, a new generator. P0C66 is the sine-side twin, P0C6C the high reading on the same line.
P0C6B 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 P0C6B
- Malfunction indicator lamp right after switching on
- No charging of the drive battery by the engine
- Reduced performance in hybrid mode
Common causes of P0C6B
- Most likelyCosine lead of the resolver shorted to ground
- PossiblePinched or crushed resolver harness near the transaxle
- PossibleShorted cosine winding in the generator resolver
- Less likelyFaulty cosine input in the power drive unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C6B 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. |
| 6B | The exact fault in that area. |
What to do next
- Note P0C6B 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 P0C6B
What does P0C6B mean?
P0C6B means "Generator Position Sensor Circuit B Low". P0C6B tells you that circuit B of the generator resolver, the cosine winding, reads too low. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C6B?
Drive gently and only to a workshop. With P0C6B the car can go into limp mode (reduced power) to protect itself.
Will P0C6B fail an emissions test?
Yes, it can. P0C6B 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 P0C6B to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P0C6B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
