P0DA6 Drive Motor B Inverter Voltage Sensor A Circuit High

P0DA6 is the upper-limit fault of the rear inverter voltage signal: the reading sticks near the top, as with a short to the sensor supply, or the bus really is overvolted. Mitsubishi checks it in the rear motor control unit of the 2018 Outlander PHEV whenever that unit is powered with 8 to 16 V; a sensor output above 4.7 V, standing for about 440 V, held for 0.3 s sets the code. The manual then looks at the other units: only if the front unit also stores P0D30 and the generator unit P1078 does it go on to the high-voltage fuse and cabling, because a shared high reading points to the battery or HV circuit. If the rear unit is alone, it is replaced straight away. The 2023 model lists the code as a maximum range check with MIL. True overvoltage at the rear inverter has its own code, P0C7A.

Likely causes

Rear motor control unit sensing faulty when no other unit reports high voltage (Mitsubishi)
Fault in the high-voltage circuit or battery when front and generator units also report high
Signal shorted to the sensor supply inside the inverter

Symptoms

  • MIL and plug-in hybrid warning on
  • Rear motor drive switched off, reduced power
