Check IATS
Ignition "OFF" & Engine "OFF".
Disconnect IATS connector.
Monitor resistance between terminal 3 and 5 of IATS connector(Component Side).
Temperature (°C) | 20 | 40 | 60 |
Resistance (KΩ) | 2.29 ~ 2.55 | 1.1 ~ 1.2 | 0.56 ~ 0.65 |
Is the measured resistance within specifications?
YES
▶ Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.
NO
▶ Substitute with a known-good IATS and check for proper operation.
