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.

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.
