Your Check Engine Light (CEL) warns you that your vehicle's computer found a malfunctioning component in your emission control system.  You may see "check engine", "service engine soon", or "check powertrain".  Or, the light may show an engine picture, perhaps with the work "check".  To determine the actual problem, the experts at Good Guys Auto Care Center use an electronic scan tool or a diagnostic computer to retrieve Diagnostic Trouble Codes (DTC).  Our ASE-certified mechanics in our Fountain Valley, Mission Viejo and Rancho Santa Margarita locations can then identify the code and perform a complete diagnostic to determine the exact cause of the problem.  

Some common issues that turn on the check engine light include:

     >  Your gas cap isn't on tight enough

     >  Water got into your engine somewhere

     >  The spark plugs don't function correctly

     >  Your vehicle is emitting high levels of pollutants

     >  One or more of your vehicle's oxygen sensors need to be replaced 

In any case, once your check engine light goes on, bring your vehicle to us.  We will conduct an inspection, diagnose the problem and resolve the issue for you.  Leaving your check engine light on can cause serious problems with your car in the long run.  A check engine light appointment goes pretty fast so stop by or give us a call.
