SEF138X
Component Description
NLEC0435
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the injector circuit, the coil in the injector is
energized. The energized coil pulls the needle valve back and
allows fuel to flow through the injector into the intake manifold. The
amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the injector remains open. The
ECM controls the injection pulse duration based on engine fuel
needs.

IGNITION COIL AND POWER TRANSISTOR
NLEC0542S01
The ignition signal from the ECM is sent to and amplified by the
power transistor. The power transistor turns on and off the ignition
coil primary circuit. This on-off operation induces the proper high
voltage in the coil secondary circuit.
