| 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.
Troubleshooting Examples of False-Alarm Occurrence from system characteristics (It’s not a problem) – Characteristics of EM Wave : EM Waves are reflected against all material and especially metal very well. Reflections of EM Waves are varies with the shape of object.
