Q: What does code P0EC8 mean?

A/C Refrigerant Temperature Sensor B Circuit. P0EC8 indicates that the air conditioning (A/C) control module has detected an out-of-range signal from the refrigerant temperature sensor B circuit, which monitors the temperature of the refrigerant leaving the evaporator or condenser. The computer compares the sensor voltage to expected values and flags the code when the signal falls outside the normal operating range for a calibrated time.
