P2E1ADrive Motor A Inverter Voltage Sensor A/B Correlation
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2E1A sets when the two DC voltage readings inside the drive motor A inverter, sensor A and sensor B, stop agreeing although they should describe the same high-voltage potential. Each value may pass its own range test; the fault lies in the mismatch. No manufacturer documents P2E1A publicly. Mitsubishi shows such a cross-check on the 2023 Outlander PHEV, where sensor A reads capacitor 1 and sensor B the main channel of capacitor 2: a gap of at least 50 V lasting 0.2 s is booked under the single-sensor codes P0D2E or P0E8D. Ford's 2019 hybrids file a gap above 60 V between the inverter input and output sensors under P0DA8. Two channels alone cannot show which one is wrong, so Mitsubishi adds the rear motor voltage as a third reference. Expect a warning and limited electric drive.
- What you may notice
- Hybrid system or drive warning lamp, MIL possible
- Reduced or no electric drive power
- Further inverter voltage codes stored at the same time
- Likely causes
- LikelyOne of the two voltage measuring channels in the inverter has drifted
- PossibleFault in the inverter or power drive unit electronics
- RarePoor high-voltage connection between the two measuring points
- RareControl software with an unsuitable comparison window
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
