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..
