Mazda CX-5 Service & Repair Manual: Manifold Absolute Pressure (Map) Sensor
Purpose/Function
-
Detects the intake air pressure introduced into the cylinder as basic information for mainly determining the fuel injection amount.
-
Detects the intake air pressure introduced into the cylinder and inputs it to the PCM as an intake air pressure signal.
Construction
-
Installed on the intake manifold.
-
A sealant diaphragm has been adopted as the detecting element for detecting the intake air pressure.
-
IAT sensor No.2 is integrated.
Operation
-
Inputs the signal, which fluctuates according to the intake air pressure, to the PCM.

Manifold Absolute Pressure (Map) Sensor Inspection
Voltage Inspection
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the MAP sensor output voltage (PID: MAP) is within the specification..

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.
1. Disconnect the negative bat ...

Master Cylinder
Purpose/Function
With the adoption of the master cylinder having an enlarged diameter (20.64
mm {0.8126 in}), brake pedal operability has been improved.
For vehicles with DSC, the diameter of the pipe between the master cylinder
and the DSC HU/CM has been increased, improving re ...
Tcs Control
Outline
The TCS control actuates torque reduction through engine control, as well
as using brake control to control traction.
NOTE:
Engine control: Engine output is lowered by fuel cut and ignition timing
control to reduce the traction, preventing driving wheel slip.
