HIGH PRESSURE FUEL PUMP INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]

id0114z9801500

Note

•  The following vacuum values are indicated by relative pressure from the fuel pressure sensor.

1.   Verify that the fuel pressure sensor is normal. (See FUEL PRESSURE SENSOR INSPECTION [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 [PCM (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.  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. (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)
