What P2E1E means
P2E1E flags a phase X current sensor signal of drive motor A above the top of its valid range. No manufacturer documents P2E1E publicly. GM's U-phase counterpart on the 2016 Volt trips above 700 A for 0.05 s within 0.1 s, Type A. The same table stops real overcurrent at 600 A through P0C01, and Ford's 2019 hybrids treat more than 600 A for 400 microseconds as motor overcurrent. The sensor limit thus lies beyond any current the inverter would tolerate, so a reading that high almost always comes from the measuring side, for instance a signal shorted to the sensor supply or an open sensor ground. Genuine excess current in phase X is P2C6B. The inverter limits or stops drive. Low side: P2E1D.
P2E1E 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 P2E1E
- Hybrid warning lamp and MIL
- Electric drive cut off or strongly limited
- Possible jolt when the inverter shuts down
Common causes of P2E1E
- Most likelySensor signal shorted to the sensor supply
- PossibleOpen ground of the phase X current sensor
- PossiblePhase X current sensor failed high
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E1E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1E | The exact fault in that area. |
What to do next
- Note P2E1E 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 P2E1E
What does P2E1E mean?
P2E1E means "Drive Motor A Phase X Current Sensor Circuit High". P2E1E flags a phase X current sensor signal of drive motor A above the top of its valid range. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E1E?
Drive gently and only to a workshop. With P2E1E the car can go into limp mode (reduced power) to protect itself.
Will P2E1E fail an emissions test?
Yes, it can. P2E1E 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 P2E1E to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2E1E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
