The Sordid Check Engine Light

Many of us have had cars long enough to be able to “see the light.” Unfortunately the light we will be discussing is not the light of heaven or the light of enlightenment. It is the dashboard Check Engine Light – the herald of failed vehicle inspections!

In most states, including Vermont, if your car’s check engine light is on, your car will not pass inspection. Many times people will take their cars to a local parts shop, where they will gladly let you use their diagnostic code checker to figure out what the problems is. Of course, the reason for this “free” service is to get you to buy whatever part comes up on the code as being defective.

The most common code that appears is the one for the O2 sensors, these are the oxygen sensors and have to do with the mix of oxygen and fuel, which determine, ultimately, how much pollution your car is emitting.

We have had several people come in who have replaced their O2 sensors only to have the light remain on or come back on quickly, again. This is because most auto part stores diagnostic tools are very basic. You need trained mechanics who will find out what actually is tripping that check engine light. Maybe it is the O2 sensor. It could very well be something else, related.

Come in and see us, if your check engine light is on and we will accurately diagnose the problem and repair it for you. If you live in Essex, Burlington, South Burlington, Colchester, Winooski, Williston, Shelburne and anywhere in the State of Vermont be sure to contact Handy’s Service Center for all your auto repair needs!
