Component Inspection

  1. Check IATS resistance.
    1. IG "OFF".
    2. Disconnect IATS connector.
    3. Measure resistance between terminal 3 and 4 of IATS connector (Component Side).

      Specification: 

      DTC P0113 RESISTANCE SPECIFICATION

    4. Is the measured resistance within specification?

      YES 

      • Go to " 2 Check ECM/PCM" as follows.

      NO 

      • Substitute with a known - good IATS and check for proper operation.
      • If the problem is corrected, replace IATS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  2. Check ECM/PCM.
    1. IG "OFF" and disconnect MAFS/MAPS connector.
    2. Connect scantool and Key "ON".
    3. Select simulation function on scantool.
    4. Simulate voltage at terminal 3 of IATS signal connector.

    5. Does the signal value of IATS change according to simulation voltage?

      YES 

      • Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO 

      • Substitute with a known - good ECM/PCM and check for proper operation.
      • If the problem is corrected, replace ECM/PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
