P0EBBA/C Compressor Motor Phase V Current Sensor Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EBB is the general circuit code for the compressor's phase V current sensor, numbered after the W-phase codes instead of at the start of the V series. The module receives no usable V-phase value at all and does not classify it further as high, low or implausible. Without that value the field-oriented control of the three-phase motor cannot work, so the drive stops. No manufacturer documents P0EBB publicly. GM's 2011 Volt monitored the phase sensors of its compressor at standstill under older codes (P0D7C and P0D7D for phase V, plus or minus 68 A, Type B). Causes are an open sensing path, a loose internal plug or a failed sensor or board. Detailed V-phase faults are P0EB5 to P0EB7; the general U and W circuit codes are P0EB1 and P0EC0.
