P0D6EA/C Compressor Motor Voltage A High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D6E means the high voltage supplied to the electric A/C compressor motor is above what the compressor is built to accept, as opposed to a sensor circuit reading too high (P0D6A). No manufacturer documents P0D6E publicly. GM handles the situation its own way: the 2011–2015 Volt and 2016 ELR compressor sets P0D6A at 450 V or more and a separate maker code, P1ECA, for a single peak of 480 V; Mitsubishi's Outlander PHEV treats over 415 V for 2 s as P0D6A. Real overvoltage is rare because the traction battery clamps the bus; possible triggers are spikes during charging or regeneration, a faulty charger or converter, or a misreading inverter. The compressor usually shuts down to protect its power stage. CARB covers such inputs under hybrid thermal-management monitoring.
