Resistance inspection
NOTE:
- The IAT sensor No. 1 is built into the MAF sensor. When replacing the IAT sensor No. 1, replace the MAF sensor/IAT sensor No. 1.
- Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION ).
- 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. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION ).
