Why Did Your Check Engine Light Come On?

check-engine-lightThere is nothing worse than driving down the road, just to see your check engine light come on. This means something has gone wrong. It may not be anything major, but it is something you should check on immediately.

Here are five of the most common reasons for your check engine light coming on:

1. Oxygen sensor needs replaced.

2. Gas cap is missing, loose, or damaged in some way.

3. Catalytic converter needs replaced.

4. Spark plugs need replaced.

5. Mass airflow sensor needs replaced.

As you can see, there are many reasons why this light could come on. The bad thing is this: as a driver, there is no way of knowing the cause for the light until you take a closer look.

Conversely, it is good to know that a qualified mechanic can diagnose the problem and suggest a repair. It may not make sense to you, but the only thing that matters is that the problem is taken care of and your vehicle is back in good working condition.

At FAR, we know how frustrating it can be to have a check engine light illuminated on your dashboard. Rather than leave well enough alone, contact us to have the issue diagnosed and the problem resolved once and for all. You will feel much better once you do so.
