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..
Specification
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.

Characteristics of Ultra High-Tensile Steel Plates
Ultra high-tensile steel plates have enhanced tensile strength compared to
previous high-tensile steel plates.
Because the strength is maintained even though the plates are thin-walled,
the ultra high-tensile steel plates ar ...
Engine Tune Up
Engine Tune-up Preparation
NOTE:
If the accelerator pedal is depressed continuously for a specified time,
the engine speed may decrease to the idle speed. This is due to the fuel cut
control operation, which prevents overheating, and it does not indicate a malfunction.
The engine s ...
Magnetic Clutch Adjustment [Manual Air Conditioner]
1. Measure the clearance around the entire circumference between the pressure
plate and A/C compressor pulley using a thickness gauge.
2. Verify the clearance.
If not within the specification, remove the pressure plate and adjust the
clearance by changing the shim (0.2 mm {0.008 i ...
