Repair Procedures: Inspection

WARNING: This page is about a different car, the 2015 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.

Turn the ignition switch OFF.
Disconnect ambient temperature sensor.

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

AMBIENT TEMPERATURE SENSOR SPECIFICATION

Ambient temperature [°C(°F)]	Resistance between terminals 1 and 2 (kΩ)
-10(14)	158.18
0 (32)	95.10
10 (50)	58.80
20 (68)	37.32

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