10NOTE: An injector that sticks open can cause this DTC. A sticking injector
will cause the engine to misfire and emit excessive black smoke from the
exhaust system.
Refer to the Service Information and perform the Fuel Injector Leak Quantity Test.
Were any problems found?All
Ye s!Using the Service Information, remove and inspect the Fuel
Injectors for signs of damage or debris that may cause the injector
to stick. Sticking injectors may cause the combustion chamber to
become black and oil soaked. Replace Injector(s) as necessary.

3/stroke for each
cylinder at each engine speed.
Did any of the cylinders exceed   0.00450 mm
3/stroke during this test?All
Ye s!Replace Fuel Injector of the cylinder(s) that had readings above  
0.00450 mm
3/stroke.
Perform ROAD TEST VERIFICATION - VER-2.
No!Go To 12
12 With the DRBIIIt, select System Test, Smooth Eng Run Check, then Cylinder Speed
Check.
NOTE: Readings for all cylinders should be close to each other. Look for one
or two cylinders to differ high or low from the other cylinders.
Did any of the cylinders differ significantly from the majority of the other cylinders?All
Ye s!Replace Fuel Injector of the cylinder(s) that had readings signif-
icantly above or below the other fuel injectors.
