Ambient Temperature Sensor Repair Procedures

Inspection

1. Check the resistance of the ambient temperature sensor between terminals 1 and 2. Check that it changes when the ambient temperature changes.

   

   1. Ambient Temperature Sensor (+)

   2. Sensor Ground

Diagnosis Using GDS

1. 1
   The Heating, Ventilation and Air Conditioning (HVAC) system can quickly diagnose faulty parts using the Global Diagnostic System (GDS).
   The Diagnostic System (GDS) provides the following information. (1) Self-diagnosis: Check the Diagnostic Trouble Code (DTC) and display. (2) Current data: Check the input/output status of the system. (3) Actuation test: Check the operating status of the system. (4) Additional functions: Other controls such as system option and zero point adjustment.
2. 2
   Select "Vehicle Model" and the system to be checked to inspect the vehicle with the tester.
3. 3
   Select the Current Data menu to check the current status of the input/output data. The input/output data for the sensors related to the ambient temperature sensor can be checked.

   

Replacement

1. 1
   Disconnect the negative (-) battery terminal.
2. 2
   Remove the front bumper. (Refer to Body - "Front Bumper Cover")
3. 3
   Disconnect the connector (A) and remove the ambient temperature sensor (B).

   

4. 4
   To install, reverse the removal procedure.
