Fuel System, Performing Leak Test

Fuel System, Performing Leak Test

- Allow the engine run a few minutes at idle and then stop it. The fuel system bleeds itself.

- Check the fuel system for leaks.

If there are leaks even though the correct tightening specification was used, replace the affected component.

- Perform a road test where the accelerator pedal is pressed all the way down at least one time. Then check the high pressure area again for leaks.

• If there is still air in the fuel system, the engine may switch to emergency mode during the road test. Turn off the engine and erase the Diagnostic Trouble Code (DTC) memory. Then continue the road test.
