INTAKE AIR TEMPERATURE (IAT) SENSOR INSPECTION [SKYACTIV-G 2.0]
IAT Sensor No.1
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.
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
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.
Specification (Reference)
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 [SKYACTIV-G 2.0].)

IAT Sensor No.2
Resistance inspection
NOTE:
The IAT sensor No.2 is built into the MAP sensor. When replacing the IAT sensor No.2, replace the MAP sensor/IAT sensor No.2.
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
2. Remove the following parts:a. Wiper arm (See WIPER ARM AND BLADE REMOVAL/INSTALLATION.)b. Cowl grille (See COWL GRILLE REMOVAL/INSTALLATION.)c. Front suspension tower bar (Vehicles with front suspension tower bar) (See FRONT SUSPENSION TOWER BAR REMOVAL/INSTALLATION.)d. Air box complete (See AIR BOX COMPLETE REMOVAL/INSTALLATION.)
3. Disconnect the MAP sensor/IAT sensor No.2 connector.
4. Remove the screw. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
5. Remove the MAP sensor/IAT sensor No.2. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
6. Measure the resistance between MAP sensor/IAT sensor No.2 terminals A and B.< Previous Next >
