High Pressure Fuel Pump Inspection

HIGH PRESSURE FUEL PUMP INSPECTION [SKYACTIV-G 2.0]

NOTE:
- The following vacuum values are indicated by relative pressure from the fuel pressure sensor.

1. Verify that the fuel pressure sensor is normal. Testing and Inspection

2. Connect the M-MDS to the DLC-2.






3. Turn the ignition switch to the ON position (Engine off).

4. Select the "FUEL_PRES", "LOAD" and "RPM" PIDs on the M-MDS. On-Board Diagnostic Test

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 verified, replace the high pressure fuel pump. High Pressure Fuel Pump Removal/Installation
