The malfunction indicator lamp is usually known as the “check engine light“, “service engine soon light”, or a picture of an engine icon. Modern vehicles are equipped with a computer which controls the engine and transmission systems.  When the computer detects a malfunction with one or more of the components, it stores the corresponding trouble code(s) in its memory.

Check Engine Light Diagnosis Coupon in Santa MariaWhenever one of these fault codes are present, the onboard computer will illuminate the “check engine” or “service engine soon” light to tell you there is a problem. Our experienced mechanics are equipped with state of the art troubleshooting equipment designed to scan and retrieve fault codes from the vehicle computer.  These fault codes are then analyzed, and further testing and troubleshooting are performed to pinpoint the exact problem.  If your check engine light is on, it’s not something to ignore.  It’s possible that a check engine light could be caused by something as simple as a loose gas cap, but often times the problem is more involved and should not be neglected.  Failure to have a check engine light malfunction diagnosed and repaired in a timely manner could actually allow the problem to spread and effect other components.

Don’t disconnect the battery, don’t put tape over it, and don’t ignore it any longer.  Print your coupon and give us a call today at 347-0076.  Main Street Shell Service provides auto diagnostic services 6 days a week, Monday through Saturday.
