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. 1. Sensor Ground 2. Ambient Sensor Signal Specification Ambient temperature [°C(°F)] Resistance between terminals 1and 2 (kΩ) -30(-22) 480.41 -20(-4) 271.21 -10(14) 158.18 0 (32) 95.10 10 (50) 58.80 20 (68) 37.32 30(86) 23.76 40(104) 16.13 50(122) 10.95

4.	If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.

5.	If the problem is corrected, replace the ambient temperature sensor.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the front bumper. (Refer to BD group - "Front Bumper")

3.	Disconnect the connector and then remove the ambient temperature sensor (A).

4.	Installation is the reverse order of removal.
