P0DA7 is meant for a rear inverter voltage reading that jitters or drops out briefly without staying out of range long enough for P0DA5 or P0DA6. No manufacturer documents this code publicly. The neighbouring Mitsubishi checks give the time scale: the rear motor unit of the Outlander PHEV needs 0.3 s outside its window for the low or high fault, and the 2023 plausibility test waits 0.2 s, so faster glitches call for a separate detector. Denso's patent US9819293B2 compares the measured inverter input voltage with a value estimated from the motor control loop, an approach that also exposes an unsteady sensor. Likely triggers are a loose low-voltage plug at the inverter, a high-voltage terminal with poor contact, or sensing electronics that fail with heat. The hybrid warning may come and go.

Likely causes

Low-voltage connector at the rear inverter with intermittent contact
High-voltage terminal at the rear inverter not tightened properly
Voltage sensing electronics failing with temperature or vibration

Symptoms

  • Hybrid warning that appears and clears
  • Brief loss of rear drive power
