The battery is the power source for the *ecu* that receives inputs from the various monitors of the vehicle.<\/p>\n\n

The *mass air flow sensor* monitors the amount of air flow as demanded by the engine based on the *throttle position sensor* from the driver's input.<\/p>\n\n

Older vehicles speed is monitored by the *wheel speed sensor* as well as the turbine speed sensor.<\/p>\n\n

There are many different sensors that send infomation to the onboard computer and these include *fuel temperature sensors* and *air intake temperature sensors* which measure against atmospheric pressure and heat\/cold. Fuel tanks also have *pressure sensors* for emmissions related standards.<\/p>\n\n

There are many different colors of *electrical wiring* in a vehicle, each having its own connections. Most wiring has more than one color in the casing.<\/p>\n\n

The engine management system also monitors exhaust gas temp in oder to determine the efficiency of the *catalytic convertor* and its oxygen storage capacity. *Air fuel ratio sensors* and *oxygen sensors* are used to check and correct the operation and effeciency of the engine by the system.<\/p>\n\n
