Mazda CX-5 Service & Repair Manual: High Pressure Fuel Pump Inspection
NOTE:
-
The following vacuum values are indicated by relative pressure from the fuel pressure sensor.
1. Verify that the fuel pressure sensor is normal..
2. Connect the M-MDS to the DLC-2.
3. Switch the ignition ON (engine off).
4. Select the “FUEL_PRES”, “LOAD” and “RPM” PIDs on the M-MDS..
CAUTION:
-
If the engine is run at a high speed, it could be damaged. When racing the engine, be careful not to increase the engine speed suddenly.
5. After the “LOAD” PID is 60% or more
while the engine is raced with the accelerator pedal fully depressed, verify that the “FUEL_PRES” PID is approx. 15.0 MPa {153 kgf/cm2, 2176 psi}
.
-
If not as specified, replace the high pressure fuel pump..

Ebd Control
Outline
EBD control uses the ABS system to control brake fluid pressure distribution
to the rear wheels so that they do not lock-up prior to the front wheels during
braking, thereby preventing the loss of handling stability.
Feature
EBD control has independent control syste ...
