What P0C4E means
P0C4E says the resolver offset of drive motor A was learned, yet the learned value is unacceptable. That offset lines up the zero point of the resolver with the rotor magnets. GM rejects a correction angle beyond 30 degrees, or a new value that differs from the stored one by more than 10 degrees; the learn happens at key-off with the motor under 20 rpm and over 192 V on the DC link. Volt and ELR tables rate it Type A, and from 2016 the deviation has to show up on five key-off cycles. Kia links P0C4E00 on 2022-24 Sorento PHEV AWD to a jerky change between electric and hybrid drive and cures it with a new transaxle plus updated hybrid control software (TSB TRA112). P0C17 is the case with no valid learn at all.
P0C4E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 10 hours
- Clears after repairAfter a drive cycle
Symptoms of P0C4E
- Malfunction indicator lamp, often first noticed after a repair
- Jerk or rough feel when switching between electric and hybrid drive
- Reduced electric drive power
Common causes of P0C4E
- PossibleResolver or rotor position shifted after replacing the motor, resolver stator or transaxle
- PossibleInternal transaxle fault on affected Kia Sorento PHEV models (TSB TRA112)
- PossibleHybrid or motor control software that needs an update
- Less likelyDamaged resolver that delivers a shifted angle
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0C4E 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. |
| 4E | The exact fault in that area. |
What to do next
- Note P0C4E 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 P0C4E
What does P0C4E mean?
P0C4E means "Drive Motor A Position Exceeded Learning Limit". P0C4E says the resolver offset of drive motor A was learned, yet the learned value is unacceptable. It is a generic code, so it means the same on every make.
Is it safe to drive with P0C4E?
Drive gently and only to a workshop. With P0C4E the car can go into limp mode (reduced power) to protect itself.
Will P0C4E fail an emissions test?
Yes, it can. P0C4E 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 P0C4E to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 10 hours of work. This is a job for a workshop.
Will P0C4E clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
