What P2E22 means
P2E22 is stored when the phase Y current sensor signal of drive motor A sticks above its upper limit. No manufacturer documents P2E22 publicly. On GM's 2016 Cadillac ELR the U/V/W counterparts fail above 800 A, judged as 4 bad samples out of 6 at 10.4 ms intervals, Type A. Notably, the V-phase checks only run while no U-phase sensor code is active, and W waits for V in the same way, presumably so that one shared fault does not set a code on every phase. If P2E22 shows up together with high codes of X or Z, look for such a common cause first, for example the sensor reference. On its own, a short between signal and supply line, or a lost sensor ground, is the likely culprit; real overcurrent in phase Y is P2C6E. Mitsubishi Electric's two-group motor patent lists a dedicated Y sensor beside those for X and Z. Low side: P2E21.
P2E22 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 P2E22
- Hybrid warning lamp and MIL
- Electric drive switched off or strongly limited
- High codes of other phases stored at the same time
Common causes of P2E22
- Most likelyPhase Y signal shorted to the sensor supply
- PossibleOpen ground of the phase Y sensor
- PossibleShared sensor reference faulty, other phases affected too
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E22 means

| 22 | The exact fault in that area. |
What to do next
- Note P2E22 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 P2E22
What does P2E22 mean?
P2E22 means "Drive Motor A Phase Y Current Sensor Circuit High". P2E22 is stored when the phase Y current sensor signal of drive motor A sticks above its upper limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E22?
Drive gently and only to a workshop. With P2E22 the car can go into limp mode (reduced power) to protect itself.
Will P2E22 fail an emissions test?
Yes, it can. P2E22 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 P2E22 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2E22 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
