Fuel Injectors

The ECM controls the ground path for each individual injector through a driver circuit located internal to the ECM. It can alter the injector on-time in milliseconds to achieve a correct air/fuel mixture based on signals received from various engine sensors. The ECM will turn injectors on and off during deceleration, traction control, misfire diagnostics and if signals from the crankshaft position sensor are intermittently disrupted.
