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.

Purge Control
Outline
An appropriate amount of evaporative gas is fed into the intake manifold
by the purge solenoid valve operation according to the engine operation conditions.
This ensures driveability and prevents release of evaporative gas into the atmosphere.
The PCM drives the purge so ...
Clutch [C66 M R]
Purpose, Function
The clutch unit transmits or cuts the drive force between the engine and
MTX according to the clutch pedal operation.
Construction/Operation
The construction/operation of the clutch unit is the same as the original
MTX (ex: G66M-R).
