Adds and removes spark and fuel based on engine temperature.
Tells ECM how much air is coming into the intake system and will tell the fuel injectors to deliver 1 pound of fuel for every 14.7 pounds of incoming air. Also is sometimes combined in to the MAF sensor housing.
Measures how much vacuum (or pressure in the case of a turbo) that the intake manifold contains. This sensor is used primarily to enable the ECM to determine the load on the engine. This sensor many times also acts as a BARO sensor which tells the ECM an approximation of elevation. The ECM will adjust spark timing and fuel delivery based on this sensor.
Measures coolant temperature for the ECM which will add timing and fuel when cold and will remove timing and fuel as the temperature increases.
Tells the ECM how much throttle is being requested, it has a range of 0% to 100%. It controls the position of the throttle plate to accelerate or decelerate.
Monitors engine detonation and retards the timing accordingly.
Monitors the end result in the exhaust and is calibrated to feedback that information to the ECM that the mixture is in fact 14.7/1, if not the ECM will adjust the fuel injector pulse width to achieve that mixture.
