In this article we will have a central system single-point fuel injector checking. The first thing we will will be set the multimeter on the scale of 200 ohms, torque measure the injector resistance, then connecting the connectors of the tester to the poles of the injector plug, regardless of polarity, i.e. each lead of the multimeter is connected indifferently to each contact of the plug from injector. Injector we shall throw an ohmic resistance in the range of 2 to 3 ohms, if your measurement gives in this range indicates that the electrical part of the injector has anticipated resistance (in this case, and only as checking try to invert the poles of the tester and you will see that the value will be the same, since as we have mentioned polarity has no effect on this measurement). If in contrast to test the injector shows us the value of 1 means that injector has its damaged electrical system since the value 1 means infinite resistance, in other words there is no continuity due to a short in the injector coil. From a failure like this last We should replace the injector, for that based on the body of the nozzle cover is removed, and then remove the screw that secures the nozzle holder. After removing this bolt proceed to remove the paper that holds the injector. Finally we exert on the injector some force down while we turn, with what we have achieved remove the nozzle. To place the new nozzle proceed in reverse order and repair will be concluded. Nozzle cleaning some bugs present in the injectors are due to carbon deposits on the nozzle, i.e. at the tip where it exits the Jet of fuel injection. These deposits can clog this hole by varying the flow of this stream and causing failure in the system.
