P0EBEA/C Refrigerant Temperature Sensor A Circuit Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0EBE is logged when the voltage from refrigerant temperature sensor A falls close to zero. For an NTC element a low voltage stands for high temperature, so the controller sees refrigerant that seems far too hot. Real heat at that level is unlikely; a signal wire chafed through to ground or a thermistor shorted internally is the usual finding. No manufacturer publishes P0EBE. GM's 2012 Volt reacts to its evaporator refrigerant sensor below 2 percent of the reference (about 0.1 V) in 40 of 50 samples as P0537, Type B, which shows how such a check is built. Expect the compressor to be held off as protection. High-voltage fault of this sensor: P0EBD.
