Mazda CX-5 Service & Repair Manual: Mass Air Flow (MAF) Sensor Inspection

Mazda CX-5 Service & Repair Manual / Engine / Intake / 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..
