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..

Accelerator Pedal, Kickdown Switch
Purpose, Function
The driver's intentions are transmitted to the PCM via the accelerator pedal.
Kickdown switch (ATX) (Applied VIN (assumed): JM3 KE2*E*D# 148107?)
If the accelerator pedal is depressed carelessly, kickdown control will be
implemented based on the accelera ...
Thermostat
Purpose, Function
When the engine coolant temperature is low, the thermostat blocks the engine
coolant passage between the radiator and engine. As a result, because engine
coolant cycles without passing through the radiator, warming is promoted.
Construction
The thermostat ...
