General Information

Component Location





General Description

The ambient temperature senor located at the center stay of the condenser detects ambient air temperature. It is a negative type thermistor whose resistance is inversely proportional to temperature. Its output is used for discharge temperature sensor, sensor fail-safe, temperature regulation door lock, blower motor level control, mix mode control and in-car humidity control

DTC Description

The ECM sets DTC B1237 if there is a short circuit in ambient temp sensor signal harness or the measured resistance value of sensor is less than threshold value (about 10.8 kOhms)
