General Description

The Evaporator sensor located at heater unit detects the core temperature and interrupts compressor relay power, in order to prevent evaporator freezing by excessive cooling. It is a negative type thermistor whose resistance is inversely proportional to temperature

DTC Description

The ECM sets DTC B1242 if there is an open circuit in evaporator sensor signal harness or the measured resistance value of sensor is more than threshold value (about 13.6 kOhms)
