Check Engine Light

Check Engine Light On in Jamestown, NC


The check engine light on your dashboard can be beneficial in alerting you to possible dangers that lurk beneath the dash. It could be pointing toward a potentially damaging flaw or defect in your vehicle. However, that being said, it could also be something small.

You never truly know what the check engine light could mean, so it is imperative that you have it checked as soon as it appears. Here are a few of the common reasons for the check engine light coming on:

  • O2 sensor needs replacing: this device measure the amount of unburnt oxygen in the exhaust. A car will continue to run even after this warning appears, but in the long run can do damage to other car parts, such as your spark plugs and catalytic converter.
  • Gas cap: this could be a potentially easy fix. The gas cap keeps the gas tank at the correct amount of pressure and helps prevent gasoline fumes from leaving the tank. Whether it needs to be tightened or replaced, it won’t take much time or effort.
  • Catalytic converter failure: the converter turns carbon monoxide into carbon dioxide. Every late-model car fueled by gasoline has one of these parts.
  • Aftermarket Alarms: if your vehicle has an aftermarket alarm, it could be wreaking havoc on the battery, triggering the check engine light, and even prevent the car from starting altogether. This can be a tricky diagnosis, which is another reason it is best to take it into a professional.

The check engine light is part of your car’s diagnosis and warning system. If it comes on, it is an indication that something is wrong, and ignoring that light can leave you on the side of the road with some costly repairs. Is your check engine light on? Call us at 336-454-5736 to get a diagnosis.
