What P2E25 means
P2E25 means the phase Z current sensor of drive motor A reports below its valid minimum. No manufacturer documents P2E25 publicly. A zero reading is not the same thing: if phase Z carries no current because a lead is open, the sensor correctly reads about zero and the open phase is judged by P2C70. Low here means beyond the negative end of the scale; GM places that limit for its U/V/W sensors between -440 A on eAssist and -800 A on the 2016 Cadillac ELR. When X and Y log low codes as well, a common cause such as the shared sensor reference or a ground in the inverter's low-voltage wiring is more likely than three failed sensors; Ford, for one, watches that reference separately. High side: P2E26.
P2E25 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E25
- Hybrid warning lamp and MIL
- Reduced electric drive
- Low codes of other phases possibly stored too
Common causes of P2E25
- Most likelyPhase Z sensor signal shorted to ground
- PossibleShared sensor reference or ground faulty
- PossiblePhase Z current sensor failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E25 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 25 | The exact fault in that area. |
What to do next
- Note P2E25 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 P2E25
What does P2E25 mean?
P2E25 means "Drive Motor A Phase Z Current Sensor Circuit Low". P2E25 means the phase Z current sensor of drive motor A reports below its valid minimum. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E25?
Drive gently and only to a workshop. With P2E25 the car can go into limp mode (reduced power) to protect itself.
Will P2E25 fail an emissions test?
Yes, it can. P2E25 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 P2E25 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2E25 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
