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 plugs and ignition wire sets, air filter
replacement, distributor cap and rotor button (where applicable).
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
- Throttle Position
Sensor
- Manifold Absolute Pressure Sensor
- Coolant
Temperature Sensor
- Exhaust Oxygen Sensor
- Crankshaft
Position Sensor
- Camshaft Position
Sensor
