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.
Medium severity. Can I keep driving?If the battery warning light comes on, you could get stranded. Turn off electrical accessories and go straight to a repair shop.
Symptoms
- Hybrid warning lamp
- Generator used only partly or not at all
- Unusual noise or vibration from the transaxle under load
Most likely causes
- Loose or twisted resolver stator changing the cosine amplitude
- Partially shorted cosine winding with weakened output
- Noise from phase leads due to damaged shielding or poor routing
- High contact resistance in the circuit B connector
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- It can trigger limp mode.
- It affects emissions.
What each character of P0C6A means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- C: Subsystem depends on the code range
- 6A: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0C6A?
If the battery warning light comes on, you could get stranded. Turn off electrical accessories and go straight to a repair shop.
What causes code P0C6A?
The most common causes are: loose or twisted resolver stator changing the cosine amplitude; partially shorted cosine winding with weakened output; noise from phase leads due to damaged shielding or poor routing.
