HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Gasoline Model)  P007011  Ambient Temperature Sensor Circuit Short to Ground  


DESCRIPTION

The thermistor assembly is installed in front of the cooler condenser assembly to detect the ambient temperature, which is used to control the air conditioning system. This sensor is connected to the combination meter assembly and detects fluctuations in the ambient temperature. This data is used for controlling the cabin temperature. The resistance of the thermistor assembly changes in accordance with the ambient temperature. As the temperature decreases, the resistance increases. As the temperature increases, the resistance decreases.

The air conditioning amplifier assembly applies a voltage to the thermistor assembly and reads voltage changes due to changes in the resistance of the thermistor assembly.
