AMBIENT TEMPERATURE SENSOR Repair Procedures

Inspection

1. Check the resistance of the ambient temperature sensor between terminals 1 and 2 to see if it changes in accordance with the change in ambient temperature.

   

   1. Ambient Temperature Sensor (+)

   2. Sensor Ground

Diagnosis with GDS

1. 1
   The heating, ventilation and air conditioning (HVAC) system can be diagnosed quickly (defective parts) using the Global Diagnostic System (GDS). ※ The GDS provides the following information. (1) Self-diagnosis: checks and displays diagnostic trouble codes (DTC). (2) Current data: checks the status of input/output signals. (3) Active test: checks system operating conditions. (4) Additional functions: in addition to control, such as zero point adjustment.
2. 2
   Select the "Vehicle Model" and the system to be checked in order to inspect the vehicle with the scan tool.
3. 3
   Select the "Current Data" menu to check the current status of the input/output data. The input/output data for the sensors corresponding 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, perform the removal procedure in reverse order.
