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 [℃(℉)]	Resistance between terminals 1and 2 (㏀)
-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.
