Installation manual

4-33
90-898305
a – Direct injector ohm test between the two connector pins (1.0 – 1.6 ohms)
b – Check between each connector pin and the metal portion of the injector,
ohms reading should be 1000 ohms or greater.
NOTE: Making resistance checks on a direct injector while still installed in
the engine can be difficult. An easy and fast way to make resistance (ohms
value) checks on direct injectors is to use service harness 84-858781A2, shown
below. This harness is normally used as a service replacement part for the
direct injector connector if it becomes damaged, but also works well to make
the required resistance and ground test while the injector is in place between
the cylinder head and fuel rail.
Service literature will be updated with this information as manuals are revised
