Ambient Temperature Sensor Repair Procedures

Inspection

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

   

   1. Ambient Temperature Sensor (+)

   2. Sensor Ground

   
   Specification

   Ambient Temperature [°C (°F)]	Resistance between terminals 1 and 2 (kΩ)
   -10 (14)	164,2
   0 (32)	97,5
   10 (50)	59,6
   20 (68)	37,46

Diagnosis Using GDS

1. 1
   The heating, ventilation, and air conditioning system faults can be quickly diagnosed using the Global Diagnostic System (GDS). ※ The GDS provides the following information: (1) Self-diagnosis: Check and display of diagnostic trouble codes (DTC). (2) Current data: Check the input/output status of system data. (3) Active 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 input/output data status. 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.
