Mazda CX-5 Service & Repair Manual: Intake Air Temperature (Iat) Sensor Inspection
IAT Sensor No.1
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.
1. Disconnect the negative battery cable..
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.
-
If not as specified, replace the MAF sensor/IAT sensor No.1..

IAT Sensor No.2
Resistance inspection
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.
1. Disconnect the negative battery cable..
2. Disconnect the MAP sensor/IAT sensor No.2 connector.
3. Remove the MAP sensor/IAT sensor No.2..
4. 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..
