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. Specification Ambient temperature [°C(°F)] Resistance between terminals 1and 2 (kΩ) -30(-22) 479.22 -20(-4) 271.45 -10(14) 158.32 0(32) 95.10 10(50) 58.76 20(68) 37.30 30(86) 24.27 40(104) 16.17 50(122) 11.00 60(140) 7.63 70(158) 5.38

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.	Remove the ambient temperature sensor (A).

4.	Installation is the reverse order of removal.
