Kia Forte: Ambient Temperature Sensor Inspection

Second generation YD (2014-2018) / Kia Forte TD 2014-2018 Service Manual / Heating,Ventilation, Air Conditioning / Air Conditioning System / Ambient Temperature Sensor Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect ambient temperature sensor.

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

Specification

Ambient temperature [°C(°F)]	Resistance between terminals 1and 2 (kΩ±3%)
-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)	24.26
40(104)	16.13
50(122)	10.95

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

5.	Replace the ambient temperature sensor if it is proved that there is a problem with it.
