P0D2EDrive Motor A Inverter Voltage Sensor A Circuit Range/Performance
- 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
- P0D2E means the inverter voltage reading of drive motor A is electrically valid but disagrees with other measurements of the same high-voltage bus. Mitsubishi shows the logic for the 2023 Outlander PHEV: with voltage control active, the power drive unit compares capacitor 1 with the rear motor unit and with both channels of capacitor 2; a gap of 100 V or 50 V held for 0.2 s sets the code, and an implausible PWM period counts too; the MIL comes on. Mercedes lists P0D2E00 in the battery management of its 2024 P3 plug-in hybrids (series 206, 223, 254, 290) when the high-voltage belt starter-alternator has failed and the engine no longer starts. So a drifting sensor and a real fault elsewhere on the bus are both possible. Hard circuit faults are P0D2D, P0D2F and P0D30.
- What you may notice
- MIL and hybrid system warning
- Engine will not start, only electric driving possible (Mercedes)
- Reduced drive power
- Likely causes
- PossibleVoltage sensing in the power drive unit drifts or reads wrong
- PossibleFault in another HV component, e.g. belt starter-alternator (Mercedes)
- RareHigh resistance or loose high-voltage connection between modules
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
