Check Engine Light
European Auto Check Engine Light Diagnostics in Herndon
The check engine light is one of the most misunderstood lights on a car's dashboard. Simply put, it means that the car's computer has detected a problem with the engine or another critical system. It could be something as simple as a loose gas cap, or it could be something more serious like a faulty oxygen sensor. However, the only way to know for sure is to have the car checked by a qualified mechanic. In some cases, the check engine light may come on due to a temporary problem that will resolve itself without any intervention. However, it is always best to err on the side of caution and have the car checked as soon as possible to avoid expensive repairs down the road.
Common Check Engine Light Repairs Include

Broken/Loose Gas Cap – One of the most common reasons for a check engine light to come on is a loose or damaged gas cap. If the gas cap is not tightened properly, it can allow fuel vapors to escape. In most cases, simply tightening or replacing the gas cap will take care of the problem.
Faulty O2 Sensor – Another common issue is a faulty oxygen sensor. The oxygen sensor is responsible for monitoring the air/fuel mixture in the engine. If it senses that the mixture is too lean (not enough fuel), it will trigger the check engine light..
Exhaust Leaks – A third common issue is an exhaust leak. Exhaust leaks can be caused by a hole in the exhaust system or a faulty gasket. Either way, they need to be fixed as soon as possible, as they can cause damage to the engine over time.
