P0EADA/C Compressor Motor Current Sensor Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EAD covers the current sensor of an electric A/C compressor, which measures how much current the motor drive takes from the high-voltage link. The controller needs this value to limit power and to shield the power stage and the high-voltage pack from overload. P0EAD is the general circuit code: the reading is absent or useless as a whole, with no low, high or plausibility verdict. Only Audi documents a sibling publicly (P0EAE on the 2016 A3 e-tron); P0EAD itself appears in no manufacturer source. GM's 2011 Volt shows how the measured value is used: above 27 A in 30 of 60 samples while the motor runs gives P0D6F, Type B. Because the sensor sits inside the compressor's power module, repair normally means the compressor assembly. Specific faults are P0EAE to P0EB0.
