High Pressure Fuel Pump Inspection

NOTE:

  1. Verify that the fuel pressure sensor is normal. (See FUEL PRESSURE SENSOR INSPECTION .)
  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. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
    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. Is the "FUEL_PRES" PID value 3.0 MPa {31 kgf/cm 2  , 435 psi}  or more while idling.
