| 1. |
The ambient temperature sensor is located at the front of the
condenser and detects ambient air temperature. It is a negative type
thermistor resistance will increase with lower temperature, and decrease
with higher temperatures. |
| 2. |
The sensor output will be used for discharge temperature
control, temperature regulation door control, blower motor level
control, mix mode control and in-car humidity control.

Inspection 1. Ignition "ON" 2. Using the scan tool. 3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change.
Inspection 1. Ignition "OFF" 2. Disconnect ambient temperature sensor. 3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.

Description A/C pressure transducer convert the pressure value of high pressure line into voltage value after measure it. By converted voltage value, engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stop the operation of compressor when the temperature of refrigerant line is so high or so low irregularl
