Fuel Injector: Testing and Inspection

Fuel Injector Circuit Check

Component Description

The fuel injector is a small, precise solenoid valve. When the ECM supplies a ground to the fuel injector, the coil in the fuel injector is energized. The
energized coil pulls the ball valve back and allows fuel to flow through the fuel injector into the intake manifold. The amount of fuel injected depends
upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains open. The ECM controls the injection pulse duration
based on engine fuel needs.

Component Inspection

FUEL INJECTOR

1. Disconnect injector harness connector.
2. Check resistance between terminals as shown in the figure.
