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..

Manifold Absolute Pressure (Map) Sensor/Intake Air Temperature (Iat) Sensor
No.2 Removal/Installation
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.

Mass Air Flow (MAF) Sensor
Purpose/Function
Detects the intake airflow amount introduced into the cylinder as basic information
for mainly determining the fuel injection amount.
Detects the intake airflow amou ...

Traction Control System (TCS)
The Traction Control System (TCS) enhances traction and safety by controlling
engine torque and braking.
When the TCS detects driving wheel slippage, it lowers engine torque and operates
the brakes to prevent loss of traction.
This means that on a slick surface, the engine adjusts automaticall ...
Windshield Wipers and Washer
The ignition must be switched ON.
WARNING
Use only windshield washer fluid or plain water in the reservoir:
Using radiator antifreeze as washer fluid is dangerous. If sprayed on the windshield,
it will dirty the windshield, affect your visibility, and could result in an accident.
Only use wind ...
