Mazda CX-5 Service & Repair Manual: Evaporative Emission (Evap) Control System
Purpose, Outline
-
Prevents release of evaporative gas into the atmosphere.
-
The intake manifold vacuum introduces evaporative gas to the intake manifold via the charcoal canister and the purge solenoid valve.

Fuel Pump Unit Removal/Installation
WARNING:
Fuel is very flammable liquid. If fuel spills or leaks from the pressurized
fuel system, it will cause serious injury or death and facility breakage. Fuel
can also irritate skin and eyes. To prevent this, always complete the “Fuel
Line Safety Procedure”, while referring ...
Refrigerant Pressure Sensor Inspection [Manual Air Conditioner]
1. Install the manifold gauge.
2. Verify the high-pressure side reading of the manifold gauge.
3. Measure the terminal voltage at PCM terminals 2BB, 2AX and 2AJ
4. Using the graph below, measure and verify the terminal voltage at 2AX.
5. Follow the PCM inspection when measuring the other ter ...
Barometric Pressure (Baro) Sensor Inspection
Voltage Inspection
NOTE:
Because the BARO sensor is integrated in the PCM, replacing the BARO sensor
includes replacement of the PCM.
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the BARO sensor output voltage (PID: BARO) is wi ...
