How Ecu Works Diagram. The electromagnetic force will move an iron core in the middle of the coil this movement opens the nozzle. Path 1 the light relay receives the voltage but since the armature is in the openoff position it stops at this point.
In the process the voltage from the ecu enters the solenoid. There are 2 types of the crankshaft position sensors. The output of an oxygen sensor is an analog voltage usually between 0 and 11 volts v.
The picture changes however when the ignition switch is in position two on.
How ecu works diagram. Some of the other components in the ecu that support the processor are. Diagram is drawn with the ignition in position 0 the off position. Other features will not work as well but frankly if the engine is dead other features dont really matter that much.
