P0C4EDrive Motor A Position Exceeded Learning Limit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Malfunction indicator lamp, often first noticed after a repair
- Jerk or rough feel when switching between electric and hybrid drive
- Reduced electric drive power
- Likely causes
- 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
- RareDamaged resolver that delivers a shifted angle
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
