HIGH PRESSURE FUEL PUMP INSPECTION [SKYACTIV-G 2.0]

1. Verify that the fuel pressure sensor is normal. (See FUEL PRESSURE SENSOR INSPECTION [SKYACTIV-G 2.0].)

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

3. Switch the ignition ON.

4. Select the “FUEL_PRES” PID on the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0)].)

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/cm², 435 psi} or more while idling.

• If not as specified, replace the high pressure fuel pump. (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
