Repair Procedures: Inspection

WARNING: This page is about a different variant/trim than selected.

Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.

AMBIENT TEMPERATURE SENSOR SPECIFICATIONS

Ambient temperature [°C(°F)]	Resistance between terminals 1 and 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

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