Component Inspection

  1. Ignition "OFF".
  2. Disconnect IATS connector.
  3. Measure the resistance between signal terminal and ground terminal of the sensor connector (Component side).

  4. 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.
