| 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.
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of compressor.
Replacement 1. Remove the condenser, and then remove the bottom cap (B) with L wrench (A) from the condenser. Tightening torque : 9.8~14.7N.m (1.0~1.5kgf.m, 7.2~10.8 lb-ft) 2. Remove the desiccant (A) from condenser using a long nose plier.
