| Description |
| 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.
Removal 1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off. 2. Disconnect the negative cable from the battery. 3. Recover the refrigerant with a recovery/charging station.
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. 1. Sensor Ground2.
