this is the basics of Vehicle electronics ,it will give a lot of useful information about ECU and sensores and actauators and thier electronic componants .
Sensors are devices convert physical quantities like temperature, pressure, speed, position and other data into either digital or analog electrical signals
Actuators are a subdivision of transducers. They are devices which transform an input signal (mainly an electrical signal) into motion. Like include electrical motors, pneumatic actuators, hydraulic pistons, relays, piezoelectric actuators, thermal bimorphs, and electro active polymers.
In this section we add some useful information about engine electronic System and it features.
