1.   Verify that the fuel pressure sensor is normal. (See FUEL PRESSURE SENSOR INSPECTION [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

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 1.5, 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/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 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
