What P2E24 means
P2E24 concerns a phase Z current reading of drive motor A that passes the electrical checks yet fails a plausibility test. No manufacturer documents P2E24 publicly. Z completes the second winding group of a two-group motor; in the Mitsubishi Electric patent X, Y and Z are star-connected and controlled separately from U, V and W, so a biased Z sensor upsets only its own group. GM's 2019 hybrid table shows the typical test on the U/V/W side: the offset learned while no motor current flows must stay within 35 A, otherwise the code sets after 0.4 s, Type A. Ford also uses the motor phase sensors to confirm that the three AC leads are connected correctly, so a skewed reading can look like a wiring problem. Circuit: P2E23; low and high: P2E25, P2E26; group sum: P2E27.
P2E24 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 P2E24
- Hybrid warning lamp and MIL
- Electric drive limited
- Uneven torque or motor noise
Common causes of P2E24
- Most likelyZero offset of the phase Z sensor drifted
- PossibleGain error of the phase Z sensor
- Less likelyFaulty measuring stage on the inverter control board
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E24 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 24 | The exact fault in that area. |
What to do next
- Note P2E24 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 P2E24
What does P2E24 mean?
P2E24 means "Drive Motor A Phase Z Current Sensor Circuit Range/Performance". P2E24 concerns a phase Z current reading of drive motor A that passes the electrical checks yet fails a plausibility test. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E24?
Drive gently and only to a workshop. With P2E24 the car can go into limp mode (reduced power) to protect itself.
Will P2E24 fail an emissions test?
Yes, it can. P2E24 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 P2E24 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2E24 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
