| Inspection |
| 1. |
Check the resistance of the ambient temperature sensor between terminals
1 and 2 whether it changes by changing the ambient temperature.
Specification
|
| 2. |
If the measured resistance is not within specification, substitute with
a known-good ambient temperature sensor and check for proper operation.
|
| 3. |
Replace the ambient temperature sensor if it is proved that there is
a problem with the sensor.
|
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal.
|
| 2. |
Remove the front bumper.
(Refer to Body - "Front Bumper Assembly")
|
| 3. |
Disconnect the connector (A) and then remove the ambient temperature
sensor (B).
|
| 4. |
Install in the reverse order of removal.

Description 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 temperature.
Description The auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging.
Inspection • Before measuring the pressure of the refriferant line, check whether the refrigerant amount is charged in accordance with the specified charging amount.
Description The In-car air temperature sensor is built in the heater & A/C control unit. The sensor consists of a thermistor that measures the inside temperature. The signal decided by the resistance value that changes in accordance with perceived inside temperature, is delivered to heater control unit, and according t
