▶

Disconnect the pressure sensor connector 

(A) and IMV connector (B) from the fuel rail.

1.

Connect the pressure tester to the fuel rail 

pressure sensor connector.

2.

Crank the engine 2 times for 5 seconds.

3.

Read the highest pressure value displayed 

on the tester display.

If the highest pressure value is 1,050 bar 

or less, refer to the section "Fuel System

How To Use Pressure Tester

▶

Press the "TEST" button on the tester to

If the button is pressed again at 4 seconds 

after starting engine cranking, the highest 

pressure is displayed on the tester.

1.

2.

The fuel rail pressure value can be checked using a diagnostic device.

(6) Low Pressure System Pressure Test

Inspection procedure

▶

All wirings/connectors and fuel lines should 

be connected and the engine should work 

properly.

Prepare a special tool for low pressure test 

and clean it thoroughly to prevent foreign 

materials from entering.

1.

2.

Disconnect the key connector for fuel filter connection, and connect both connectors to the fuel filter 

and hose.

3.

Start the engine and check visually for clogged low pressure fuel system, excessive air or air entry.

If the fuel flow is not sufficient or air is in the fuel, repair the leak area.

Static test for backleak of injector

▶

Disconnect the injector return hose and cover 

the openings with caps shaped screw 

(included in the special tool).

1.

Connect the hose of the container for 

measuring backleak to the return nipple of the 

injector.

(prevent air entry to the low pressure line)

2.

Disconnect the IMV connector of the high 

pressure pump and then fuel pressure 

sensor connector.

3.

The connector of the injector can be easily 

contaminated. Always keep it clean.

Crank the engine 2 times for 5 seconds.

Check the time for flow if injector backleak 

and confirm that it is within the specified 

range.

4.

5.

If the value is out of the specified range, 

replace the injector.
