Check engine light can be illuminated by, literally, hundreds of different conditions. It takes experience, extensive training, and latest digital tools to professionally diagnose your vehicle and get to the root cause of the check engine light.

What Should I do if the Check Engine Light comes “on”?

There are three scenarios that you should be aware of, because they necessitate different response:

  1. First, the easiest case, is if the check engine light is illuminated, but not flashing, and the car is running normally. In this case you can drive your car home, then call us for an appointment. You have a few days to get your car diagnosed. However, if you should take weeks or months to get it checked out, chances are that you are damaging your vehicle.
  2. The second scenario is if the check engine light is illuminated, steady illumination, however the engine is running rough. In this case, if you are near an auto repair shop, you should take your car to that shop. If you are far away from a shop, it’s safer to have your car towed (Have you renewed your AAA membership?). Driving with check engine light on and engine running rough can result in expensive repairs.
  3. If the check engine light is flashing on-and-off, stop as soon as it is safe to do so, and have your car towed to Adams Autoworx. This is the most severe scenario and can result in very expensive repairs if not taken seriously.

What causes the Check Engine Light to illuminate?

There are literally hundreds of conditions that can cause the check engine light to come “on”.

The top five causes are:

  1. Faulty gas cap – yes, it happens, and quite often. It’s your lucky day if this is the cause of the check engine light.
  2. Failing spark plugs – replacing spark plugs and wires will fix the problem. Relatively easy and relatively inexpensive check engine light repair.
  3. Failed mass airflow sensor - easy to diagnose and relatively inexpensive to repair.
  4. Failed oxygen sensor – timely oxygen sensor replacement will keep your vehicle’s catalytic converter from failing.
  5. Catalytic converter failure – this one hurts you pocketbook, but if it fails, you will have to have it replaced, or your vehicle will not pass the smog test.

Most of the time, if you do not luck out with the faulty gas cap, you should take your vehicle to a professional auto repair shop to have your car diagnosed by experienced technicians with professional diagnostic tools.
