Resistance inspection

NOTE:
  • Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
  1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0] ).
  2. Disconnect the MAF sensor/IAT sensor No.1 connector.
  3. Measure the resistance between MAF sensor/IAT sensor No.1 terminals A and B.
