P0D30 is the high-side partner of P0D2F: the inverter voltage signal of drive motor A stays near its upper limit. Mitsubishi checks it on the 2018 Outlander PHEV with the front motor unit supplied at 8 to 16 V; a sensor output above 4.7 V, which stands for roughly 440 V, for 0.3 s sets the code. The manual first asks whether the rear motor unit also stores P0DA6, because then a genuine overvoltage from the battery or the HV circuit is more likely than one bad sensor; fuse and cabling come next, the power drive unit last. The 2023 model uses 4.05 V at capacitor 1 for 0.16 s and turns on the MIL. A short to the sensor supply is the classic cause on the sensing side. Real overvoltage has its own code, P0C79.

Likely causes

Voltage sensing in the power drive unit shorted to supply
Real overvoltage from battery or HV circuit (both motor units report)
Loose or damaged high-voltage connection

Symptoms

  • MIL and hybrid system warning
  • Electric drive switched off or reduced
