The heart and soul of your vehicle is the internal combustion engine. The engine block features parts such as the timing chain, camshaft, crankshaft, spark plugs, cylinder heads, valves and pistons.
Of course, the vehicles need these things to run but there are also smaller components that are just as important. The solenoid is one of the important devices and is used in multiple ways to help make a car run.
Engine sensors in a vehicle are incorporated to provide the correct amount of fuel for all operating conditions. A large number of input sensors are monitored by the engine control unit.
