Replacement
[Refrigerant Temperature Sensor #1]
1.
Recover the refrigerant with a recovery/ recycling/ charging station.
•
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
•
Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.
•
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work.
2.
Seperate the charge door handle (A).
3.
Loosen the clips and bolts on the front bumper upper cover.
4.
Lift the front bumper uppser cover (A) slightly.
5.
Remove the front bumper upper cover (A) after loosening the mounting screw (B) on the side.
6.
Remove the refrigerant temperature sensor #1 (B) after disconnecting the refrigerant temperature sensor #1 connector (A).
7.
Install in the reverse order of removal.
•
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
•
Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.
•
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work.

Description
Monitors refrigerant temperature in A/C duct and sends resistance data to A/C controller. (same as the thermistor)
Temperature and resistance is inversely proportioned. ...
General Troubleshooting Information
Before Troubleshooting
1.
Check applicable fuses in the appropriate fuse/relay box.
2.
Using KIA approved battery tester, check the battery condition. Check the battery for damage and clean / tight connections.
