Check IATS Resistance

WARNING: This page is about a different car, the 2021 Hyundai Kona. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect IATS connector with ignition switch turned "OFF".
  2. Measure the resistance between signal terminal and ground terminal of the sensor connector (Component side).

    Specification: 

    Temp. (°) Resistance (kΩ) Temp. (°/°F) Resistance (kΩ)
    -40/-40 40.93 ~ 48.35 20/68 2.31 ~ 2.56
    -20/-4 13.89 ~ 16.02 40/104 1.07 ~ 1.20
    0/32 5.38 ~ 6.08 60/140 0.54 ~ 0.06
    10/50 3.48 ~ 3.9 80/176 0.29 ~ 0.33
  3. Is the measured resistance within specification?

    YES 

    • Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure

    NO 

    • Check IATS for contamination, deterioration, or damage. Substitute with a known-good IATS and check for proper operation. If the problem is corrected, replace IATS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure
