Although these microprocessors make it more difficult for you to work on your own car, some of them actually make your car easier to service.

Your Check Engine Light lets you know that your vehicle’s computer found a malfunctioning component in your emission control system. To determine the problem, our technicians use a diagnostic computer to retrieve your Diagnostic Trouble Codes (DTC). Some issues that turn on the check engine light can include:

• Your gas cap not being on tight enough
• Water got into your engine somewhere
• Spark Plugs
• Your vehicle is emitting high levels of pollutants

The computer receives information; it then sends commands to three different systems: fuel, ignition, and emission control. When a problem arises, the check engine light turns on. Our certified technicians checks to find the problem. So bring in your vehicle, we’ll check it out and you can know if that check engine light on is a real problem.
