What P2CCE means
P2CCE is reserved for the ninth section, I, of a traction battery whose controller rates the health of each section on its own. The fault is a capacity or power verdict, not an electrical one: section I no longer delivers what a healthy unit should. No manufacturer publicly documents P2CCE. The nearest published use is Audi's Q5 PHEV, which splits its pack into eight groups and therefore stops at P2CCD for group 8; a battery with nine or more independently monitored modules would continue here, followed by P2CCF for section J. CARB asks for a state-of-health monitor for hybrid storage and, for faults of cells, sensors and cell balancing, for codes that isolate the smallest replaceable unit. Where it is used, expect the MIL, a shorter electric range and, as with Audi's siblings, the replacement of a single module rather than the whole battery.
P2CCE at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 8 hours
- Clears after repairAfter a drive cycle
Symptoms of P2CCE
- MIL or hybrid system warning on
- Shorter electric range
Common causes of P2CCE
- Most likelyModule or cell group of section I aged beyond its limit
- PossibleUneven pack temperature stressing this section
- Less likelyMisjudged state of health in the battery controller
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2CCE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| CE | The exact fault in that area. |
What to do next
- Note P2CCE 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 P2CCE
What does P2CCE mean?
P2CCE means "Hybrid/EV Battery Pack I Deterioration". P2CCE is reserved for the ninth section, I, of a traction battery whose controller rates the health of each section on its own. It is a generic code, so it means the same on every make.
Is it safe to drive with P2CCE?
Drive gently and only to a workshop. With P2CCE the car can go into limp mode (reduced power) to protect itself.
Will P2CCE fail an emissions test?
Yes, it can. P2CCE 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 P2CCE to fix?
Difficulty: workshop only. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P2CCE 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.
