P0EB6A/C Compressor Motor Phase V Current Sensor Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EB6 reports that the phase V current signal reads below its permissible minimum. The compressor's power module cannot regulate phase V without it and stops the motor. Candidates are a sensing path pulled to ground, a sensor that has lost its supply or a defect on the inverter board; a problem in the refrigerant circuit cannot produce this code. No manufacturer documents P0EB6 publicly. In the first-generation Chevrolet Volt, GM treated minus 68 A or lower on phase V with the motor at rest as a sensor fault (older code P0D7D, 30 of 60 samples, Type B). Because the sensor is built in, replacing the compressor unit is the normal fix. High range: P0EB5; general V circuit: P0EBB; the phase U and W equivalents are P0EB3 and P0EB9.
