SPECIFICATION
IATS RESISTANCE SPECIFICATIONSIATS Normal Parameter 20 °C (68°F) 40°C (104°F) 80°C (176°F) Resistance 2.35 ~ 3.54MkΩ 1.11 ~ 1.19kΩ 0.31 ~ 0.32kΩ - Is resistance within the 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.
