FUEL INJECTOR BALANCE TEST WITH TECH 2

CIRCUIT DESCRIPTION

The scan tool first energizes the fuel pump and then the injectors for a precise amount of time allowing a measured amount of fuel into the manifold.
This causes a drop in system fuel pressure that can be recorded and used to compare each injector.
