A4: CHECK THE FUEL INJECTOR BACK LEAK AFTER FUEL SYSTEM PRESSURE TEST
A5: FUEL INJECTOR BACK LEAK TEST FAILURE MODE 1
Multiply the lowest recorded value by 1.4 to
7
calculate the maximum permissible value
(maximum permissible value = minimum
recorded value + 40%).
Example:
Quantity of lowest volume container = 10 ml
1.4 X 10 ml = 14 ml
Maximum permissible value = 14 ml
Are the volumes of fuel in each of the special tool
containers lower than the calculated maximum
permissible variation value?
Yes
NO fault is indicated with the fuel injectors. To
continue diagnostics, RETURN to the Symptom
Chart.
No
If one or more fuel volumes in the special tool
containers has a volume above the maximum
permissible variation value, using WDS Program
Module Routine, INPUT the fuel injector correction
values. TEST the system for normal operation.
Invert the containers of the special tool, raise the
1
containers above the engine and allow the collected
fuel to drain into the clear plastic hoses connecting
the containers to the fuel injectors.
Measure and record the length of clear plastic hose
2
containing fuel for each fuel injector.
Do one or more clear plastic hoses contain no fuel and
one or more have a recorded value greater than 21 cm
in length?
Yes
GO to A5.
No
GO to A6.
Install new fuel injectors for those injectors with
1
recorded values of greater than 21 cm.
