Repair Procedures: Inspection

WARNING: This page is about a different car, the 2023 Hyundai Palisade. However, it is still accessible from the selected car via links, so may be relevant.

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

TEMPERATURE SPECIFICATION

Ambient temperature [°C (°F)]	Resistance between terminals 1 and 2 (KΩ)
-30	507

-10	164.2
0	97.5
10	59.6
20	37.46
30	24.18
40	16

If the measured resistance is not within specification, substitute with a known-good ambient temperature sensor and check for proper operation.
Replace the ambient temperature sensor if it is proved that there is a problem with the sensor.
