P2E24Drive Motor A Phase Z Current Sensor Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
