We’ve all experienced that terrifying feeling when our car’s “Check Engine” light comes on. That annoying little light can be triggered by many different reasons. Your vehicle is built with a highly intelligent computer system that is connected to sensors all throughout your vehicle. Your check engine light will illuminate when something breaks or isn’t working properly.  The sensors will send a signal to your vehicle’s computer indicating there is a problem. Ignoring this warning, especially when the light is flashing, is never a good idea and can eventually lead to costly repairs.

At Koester Automotive and Collision Center we have the latest, state-of-the-art computer equipment to properly diagnose your check engine light. After our full diagnostic scan, we will provide you with our recommendations to restore your vehicle back to optimum working condition.

Our expertly trained staff is equipped to assess and diagnose any problem that may be triggering that pesky light. Don’t drive around wondering if there’s a bigger problem. Get to the source of your CEL warning. With the help of our team you can get the issue resolved quickly and affordably. Remember, an informed driver is always a safer driver.

Common Check Engine Light Triggers:

  • Gas cap is loose. This problem doesn’t require any replacement parts or cost, so it’s a good place to start. Simply check to make sure your gas cap isn’t loose and tighten it down if it is. It may take some time for the check engine light to go off, but it eventually should if that was the problem.

  • Oxygen sensor needs to be replaced.Your car has 2-4 oxygen sensors. These sensors monitor your vehicle’s air-fuel mixture and adjust as needed. When one isn’t working properly, it decreases your gas mileage and increases the amount of emissions that are produced.Sherman Oaks body shop Sherman Oaks auto body shop Sherman Oaks auto body repair Sherman Oaks bodyshop Sherman Oaks collision repair Sherman Oaks car painting Sherman Oaks dent repair Sherman Oaks auto body shops Sherman Oaks auto restoration Sherman Oaks auto body repair shops Sherman Oaks auto body shop near me Sherman Oaks auto body repair shop Sherman Oaks cheap auto body repair Sherman Oaks auto body repairs Sherman Oaks auto body repair estimate Sherman Oaks mobile auto body repair Sherman Oaks auto body shop supplies Sherman Oaks auto body shop reviews Sherman Oaks auto body rust repair Sherman Oaks vehicle restoration Sherman Oaks car repainting Sherman Oaks car repainting Sherman Oaks best auto body shop Sherman Oaks local auto body shops Sherman Oaks auto body repair estimates body shop in Sherman Oaks auto body shop in Sherman Oaks auto body repair in Sherman Oaks Best body shop in Sherman Oaks collision repair in Sherman Oaks car painting in Sherman Oaks dent repair in Sherman Oaks car painting in Sherman Oaks car restoration in Sherman Oaks auto body shops in Sherman Oaks auto restoration in Sherman Oaks auto body repair shops in Sherman Oaks auto body shop near me in Sherman Oaks auto body repair shop in Sherman Oaks Best auto body repair in Sherman Oaks auto body repairs in Sherman Oaks auto body repair estimate in Sherman Oaks auto body shop reviews in Sherman Oaks auto body rust repair in Sherman Oaks best auto body shop in Sherman Oaks local auto body shops in Sherman Oaks auto body repair estimates in Sherman Oaks Encino body shop Encino auto body shop Encino auto body repair Encino bodyshop Encino collision repair Encino car painting Encino dent repair Encino auto body shops Encino auto restoration Encino auto body repair shops Encino auto body shop near me Encino auto body repair shop Encino cheap auto body repair Encino auto body repairs Encino auto body repair estimate Encino mobile auto body repair Encino auto body shop supplies Encino auto body shop reviews Encino auto body rust repair Encino vehicle restoration Encino car repainting Encino best auto body shop Encino local auto body shops Encino auto body repair estimates body shop in Encino auto body shop in Encino auto body repair in Encino Best body shop in Encino collision repair in Encino car painting in Encino dent repair in Encino car painting in Encino car restoration in Encino auto body shops in Encino auto restoration in Encino auto body repair shops in Encino auto body shop near me in Encino auto body repair shop in Encino Best auto body repair in Encino auto body repairs in Encino auto body repair estimate in Encino auto body shop reviews in Encino auto body rust repair in Encino best auto body shop in Encino local auto body shops in Encino auto body repair estimates in Encino Sherman Oaks Tune-Up Sherman Oaks mechanics Sherman Oaks brakes Sherman Oaks auto repair Sherman Oaks mechanic Sherman Oaks oil change Sherman Oaks automotive repair Sherman Oaks car service Sherman Oaks auto body Sherman Oaks car repair Sherman Oaks auto service Sherman Oaks transmissions Sherman Oaks auto mechanics Sherman Oaks auto shop Sherman Oaks automotive service Sherman Oaks glass replacement Sherman Oaks windshield repair Sherman Oaks repair windshield Sherman Oaks auto shops Sherman Oaks car repair service Sherman Oaks auto repair service Sherman Oaks auto repair and service Sherman Oaks auto service and repair Sherman Oaks vehicle repair Sherman Oaks auto services Sherman Oaks car auto repair Sherman Oaks car repair services Sherman Oaks transmission problems Sherman Oaks car maintenance Sherman Oaks car shop Sherman Oaks car repairs Sherman Oaks auto repairs Sherman Oaks engine repair Sherman Oaks auto mechanic Sherman Oaks brake repair Sherman Oaks car shops Sherman Oaks auto shop repair Sherman Oaks automobile repair Sherman Oaks oil change coupons Sherman Oaks auto maintenance Sherman Oaks auto repair shop Sherman Oaks transmission repair Sherman Oaks auto tech Sherman Oaks auto repair services Sherman Oaks truck repair Sherman Oaks automotive mechanic Sherman Oaks auto repair shops Sherman Oaks windshield glass repair Sherman Oaks transmission fluid Sherman Oaks auto repair mechanic Sherman Oaks auto body shop Sherman Oaks auto body shops Sherman Oaks windshield auto glass Sherman Oaks autoglass replacement Sherman Oaks auto body parts Sherman Oaks automotive maintenance Sherman Oaks auto transmission service Sherman Oaks car problems Sherman Oaks car air conditioning Sherman Oaks auto air conditioning service Sherman Oaks transmission service Sherman Oaks transmission services Sherman Oaks car mechanics Sherman Oaks car mechanic Sherman Oaks clutch repair Sherman Oaks car window repair Sherman Oaks car window replacement

  • Catalytic converter needs to be replaced. Replacing your catalytic converter can get expensive, but often it only breaks if some of these lesser problems are ignored for a long time. The catalytic converter is important because it reduces the amount of harmful gases that come out of your car’s exhaust.

  • Mass air flow sensor needs to be replaced. The mass air flow sensor monitors the fuel injection system and how much air is getting into the engine. If this sensor is broken, it decreases your gas mileage and often causes your car to stall.

  • Spark plugs and wires need to be replaced. Spark plugs need to be replaced periodically depending on the age of your car. When they are wearing out, they’ll start to misfire and cause issues with your vehicle’s combustion chamber.
