P0DA5Drive Motor B Inverter Voltage Sensor A Circuit Low
- 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
- P0DA5 reports that the rear inverter voltage signal sits at the bottom of its range, the classic result of an open circuit, a short to ground or no high voltage arriving at all. Mitsubishi sets it in the rear motor control unit of the 2018 Outlander PHEV when, with the propulsion system active, the sensor output stays below 0.5 V, roughly 10 V on the bus, for 0.3 s. If the front unit and the generator unit report undervoltage too (P1A1B, P104D), the manual inspects the high-voltage fuse, cabling, battery section voltages and bus bars; otherwise it checks the torque of the rear battery cable at both ends before replacing the rear unit. A loose cable can therefore mimic a sensor fault. The 2023 model lists the code as a minimum range check with MIL. The high side is P0DA6.
- What you may notice
- MIL and plug-in hybrid warning on
- Rear motor drive switched off
- Possible no-READY condition if other units also lose voltage
- Likely causes
- PossibleRear high-voltage battery cable (P and N lines) loose or damaged
- PossibleHigh-voltage fuse not seated or loose bus bar in the battery
- PossibleSensing circuit in the rear motor control unit failed
- RareFault inside the traction battery pack
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
