Computerized Engine
To comply with Federal Exhaust Emission and Fuel Economy regulations, modern vehicles are equipped with advanced electronic engine control systems, eliminating the need for routine adjustments. The only scheduled services typically required involve replacing spark plugs and filters. Traditional tune-ups, as they were once known, have become obsolete.
Engine Control Computer
The vehicle’s computer receives data from an array of sensors and switches, which transform engine operating conditions into electrical signals. These signals, in accordance with the stored information and instructions in the computer program, are subsequently relayed to three key systems:
- Ignition System
- Fuel System
- Emission Control System
The sensors responsible for monitoring one or more of these systems encompass:
- Mass Airflow Sensor
- Throttle Position Sensor
- Manifold Absolute Pressure Sensor
- Coolant Temperature Sensor
- Exhaust Oxygen Sensor
- Crankshaft Position Sensor
- Camshaft Position Sensor
These sensors play a crucial role in maintaining optimal engine performance and emissions control.
