The check engine light might not be as bad as you think.

Common Causes of a Check Engine Light

-A loose or faulty gasoline cap.  If your gas cap is loose it can release vapors and throw off the fuel system.  This should be the first thing you check when your check engine light turns on.  This is by far the easiest to fix; tighten the cap and continue driving.  If that was the problem the check engine light should go off, if not, you may need to get car repair in Cincinnati.

-A faulty oxygen sensor.  An oxygen sensor that isn’t working properly should be replaced so it can properly change your car’s fuel and oxygen mixture.

-A faulty mass airflow sensor.  An airflow sensor usually fails due to an improperly installed air filter.  Replace your air filter at least once a year to prevent it from failing.

Don’t ever ignore the check engine light.  You should schedule an appointment to have your car diagnosed so you can know what’s wrong with it and get it back to working properly.  Mike Castrucci Ford of Milford is the place to go for all of your auto repair and car maintenance service in Cincinnati.
