IAT Sensor No.1

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.

Function inspection

1.Connect the M-MDS to the DLC-2.

2.Switch the ignition ON (engine off).

3.Display the PID IAT. (See PID/DATA MONITOR INSPECTION.)

4.Compare the voltage and temperature indications for the PID IAT with the standard in the table indicated below.

• If they do not match the standard, 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 (WITHOUT CYLINDER DEACTIVATION (US))].)

IAT Sensor No.2

Note

• Because the IAT sensor No.2 is integrated in the MAP sensor, replacing the IAT sensor No.2 includes replacement of the MAP sensor/IAT sensor No.2.

Function inspection

1.Connect the M-MDS to the DLC-2.

2.Switch the ignition ON (engine off).

3.Display the PID IAT2. (See PID/DATA MONITOR INSPECTION.)

4.Compare the voltage and temperature indications for the PID IAT2 with the standard in the table indicated below.

• If they do not match the standard, perform the resistance inspection. (See Resistance inspection.)

Resistance inspection

1.Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)

2.Remove the MAP sensor/IAT sensor No.2. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

3.Measure the resistance between MAP sensor/IAT sensor No.2 terminals A and B.

• If not as specified, replace the MAP sensor/IAT sensor No.2. (See MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO.1 REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
