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.
- Disconnect the negative battery cable. (Refer to NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
- Disconnect the MAF sensor/IAT sensor No. 1 connector.
- Measure the resistance between MAF sensor/IAT sensor No. 1 terminals A and B.
- If not as specified, replace the MAF sensor/IAT sensor No. 1. (Refer to MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION .)
