Modern Vehicle Control Computers
A network of sensors and switches convert and monitor engine operating conditions into electrical signals. The computer receives this information and commands are sent to three different systems: ignition, fuel, and emission control.
Whenever a problem arises (as seen by that nagging "check engine" light), our service pros check whatever command is prompted, in addition to the status of your engine control computer and sensors. That way you'll know if your vehicle's performance is caused by a real problem, or just a sensor/computer issue.
