Mazda 3 Service Manual: Intake Air Temperature (Iat) Sensor Inspection [Mzr 2.0, Mzr 2.5]
Resistance Inspection
NOTE:
-
Because the IAT sensor is integrated in the MAF sensor, replacing the IAT sensor includes replacement of the MAF/IAT sensor.
1. Remove the battery cover..
2. Disconnect the negative battery cable..
3. Disconnect the MAF/IAT sensor connector.
4. Measure the resistance between MAF/IAT sensor terminals D and E.
-
If not as specified, replace the MAF/IAT sensor..
