What P2E1F means
P2E1F stands for a circuit fault of the phase Y current sensor of drive motor A that is not sorted into a low or high case. No manufacturer documents P2E1F publicly, and even the U/V/W equivalents of this general code see little use: GM's 2013 to 2019 hybrid tables cover the phase sensors with offset, low, high and sum checks only, while Ford's 2019 hybrid summary says that current sensor faults of its motor inverter end up in the phase current codes P0A5D, P0A60 and P0A63 or in P0BFD. Which code a car stores for the same defect thus depends on the maker. Y is the middle phase of the second winding group; a Mitsubishi Electric patent gives each of X, Y and Z its own sensor. Check the inverter's low-voltage connector and supply first. Range check: P2E20; low and high: P2E21, P2E22.
P2E1F 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 P2E1F
- Hybrid warning lamp and MIL
- Electric drive limited or switched off
- Other phase current codes may be stored as well
Common causes of P2E1F
- Most likelyPhase Y current sensor in the inverter failed
- PossiblePoor contact at the inverter's low-voltage connector
- PossibleSensor supply or ground interrupted
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E1F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 1F | The exact fault in that area. |
What to do next
- Note P2E1F 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 P2E1F
What does P2E1F mean?
P2E1F means "Drive Motor A Phase Y Current Sensor Circuit". P2E1F stands for a circuit fault of the phase Y current sensor of drive motor A that is not sorted into a low or high case. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E1F?
Drive gently and only to a workshop. With P2E1F the car can go into limp mode (reduced power) to protect itself.
Will P2E1F fail an emissions test?
Yes, it can. P2E1F 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 P2E1F to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2E1F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
