P0EB5A/C Compressor Motor Phase V Current Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EB5 is the high-range fault of the phase V current sensor in the compressor inverter. The reading lies above the window the sensor can produce in normal service, which points to a short towards supply voltage, a defective sensing element or an internal fault in the power module rather than to real overcurrent. Unusually, the V-phase codes start with high, low and plausibility, while the general V circuit code comes later as P0EBB. No manufacturer documents P0EB5 publicly. GM's 2011 Volt detected a stuck V-phase sensor at standstill at plus 68 A or more under the older code P0D7C, Type B. The compressor drive is switched off, and refrigerant-based battery cooling may be lost with it. Related codes: P0EB6, P0EB7 and P0EBB.
