Engine Control Computer

	Manifold Absolute Pressure Sensor
	Coolant Temperature Sensor
	Exhaust Oxygen Sensor
	Crankshaft Position Sensor
	Camshaft Position Sensor

In order to meet Federal Exhaust Emission and Fuel Economy regulations, today's vehicles are equipped with highly sophisticated electronic engine control systems. These systems do not require periodic adjustments. The only services required on a scheduled basis are spark plug and filter replacement. Tune-ups, as we knew them, are no longer necessary.

	Engine Control Computer
	The computer receives information from a network of sensors and switches that convert engine operating conditions into electrical signals. Based on the information and instructions stored in the computer program, commands are then sent to three primary systems:
	Ignition System
	Fuel System
	Emission Control System

	The sensors that monitor one or more of these systems include:
	Mass Airflow Sensor Back to Top

	Throttle Position Sensor Back to Top

	Manifold Absolute Pressure Sensor Back to Top

	Coolant Temperature Sensor Back to Top

	Exhaust Oxygen Sensor Back to Top

	Crankshaft Position Sensor Back to Top

	Camshaft Position Sensor Back to Top
