Fuel Injector
Description
The fuel injectors are positioned in the intake manifold with the nozzle ends directly above the intake valve port.
Operation
Injector operation is controlled by a ground path provided for each injector by the Engine Control Module (ECM).
Injector on-time (pulse-width) is variable, and is determined by the ECM. Based on the engine operating conditions,
the ECM will control injector pulse-width operation to obtain optimum performance.
NOTE :
• Clean injectors regularly with an approved method.
