What P2C95 means
P2C95 is the upper-limit counterpart of P2C94: the voltage on the feed for the contactor coil drivers exceeds what the battery controller accepts. An excessive supply is less common than a weak one, but it heats the coils and stresses the driver transistors, and it can mean the measurement is wrong, for instance when the sense line touches a higher potential or the feed regulator inside the controller has failed. LG Energy Solution patent US12007445B2 shows that controllers measure this supply before each contactor closes; an upper limit is the logical extension, although the patent itself deals with undervoltage. No manufacturer documents P2C95 publicly. Depending on strategy the controller may refuse to close contactors or open them, so loss of ready mode is possible. CARB requires monitoring of hybrid components.
P2C95 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2C95
- Hybrid or EV system warning
- Vehicle may not become ready or may shut down HV
Common causes of P2C95
- PossibleSupply or sense line shorted to a higher voltage
- PossibleSupply regulator or measurement in the battery controller faulty
- Less likely12 V system overvoltage from a faulty DC/DC converter or jump start
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C95 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. |
| 95 | The exact fault in that area. |
What to do next
- Note P2C95 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 P2C95
What does P2C95 mean?
P2C95 means "Hybrid/EV Battery Contactor Control Supply Circuit High". P2C95 is the upper-limit counterpart of P2C94: the voltage on the feed for the contactor coil drivers exceeds what the battery controller accepts. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C95?
Drive gently and only to a workshop. With P2C95 the car can go into limp mode (reduced power) to protect itself.
Will P2C95 fail an emissions test?
Yes, it can. P2C95 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 P2C95 to fix?
Difficulty: hard. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P2C95 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
