General Information

Component Location





General Description

The ambient temperature sensor 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 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 B1238 if there is an open circuit in ambient temp sensor signal harness or the measured resistance value of the sensor is more than the threshold value (about 527 Kohms)

DTC Detecting Condition





Specification

** Resistance value of ambient temp.sensor as a function of temperature.
