P0EB0A/C Compressor Motor Current Sensor Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EB0 flags a current sensor signal at the top end of its range, beyond what the compressor drive could ever draw. It differs from a genuine overcurrent such as P0D6F, where the measurement is trusted and the motor is overloaded: here the signal itself is suspect, for example after a short to a supply voltage or a failed sensing element. No manufacturer documents P0EB0 publicly. GM's 2011 Volt gives a feel for normal limits: more than 27 A over 30 of 60 samples counts as excessive load there, Type B. CARB demands range checks for inputs that hybrid thermal management relies on. If the reading looks plausible after a restart, a stiff compressor or an overfilled refrigerant circuit should still be ruled out. The low counterpart is P0EAF.
