Mazda CX-5 Service & Repair Manual: Mass Air Flow (MAF) Sensor Inspection
Visual Inspection
1. Remove the MAF sensor/IAT sensor No.1..
2. Visually inspect the MAF sensor for the following:
-
Damage, cracks, soiling
-
Rusted sensor terminal
-
Bent sensor terminal
-
If there is any malfunction, repair or replace the MAF sensor/IAT sensor No.1..
Voltage Inspection
1. Disconnect the negative battery cable..
2. Remove the MAF sensor/IAT sensor No.1 without disconnect the connector..
3. Reconnect the negative battery cable..
4. Connect the M-MDS to the DLC?2.
5. Switch the ignition ON (engine off or on).
6. As the air gradually approaches the MAF detection part of the MAF sensor/IAT sensor No.1, verify that the MAF sensor output voltage (PID: MAF) varies..
-
If not as verified, replace the MAF sensor/IAT sensor No.1..
