It can be frustrating not knowing why the check engine light is on, especially when you own a foreign vehicle that sometimes requires expensive repairs. The thing about a check engine light is that it can come on for several reasons, so making the right repair might be difficult without assistance from a mechanic. It is a good idea to get the problem fixed in a timely manner in case it is something minor. Waiting too long to get something minor repaired in a vehicle can eventually lead to major problems. This article explains some of the reasons for a check engine light to suddenly come on.

The Battery Is in Need of Attention

A problematic battery is one of the common things that can cause the check engine light to suddenly come on. There are a few problems that can cause the battery to not function properly. For example, it is possible that the battery is low on fluid, but it can easily be replaced. In some cases, the battery is simply not powerful enough to help your vehicle fully function. The check engine light may have come on to signify that the battery is in need of being recharged.

Exhaust Gases Are Not Being Properly Catalyzed

It is important for exhaust gasses to be catalyzed in a vehicle. Basically, the gasses must be made less harmful so they will be better for the environment. There is a part that is called the catalytic converter inside of your vehicle that is responsible for handling the exhaust gasses. When the converter has become problematic, it can lead to the check engine light coming on. A mechanic can inspect the converter to find out if a repair or replacement is necessary.

Something Is Wrong With the Fuel

The engine must receive the fuel that it needs in order to properly run. Just because you put fuel in your vehicle on a regular basis, it doesn't mean that the engine is getting a sufficient amount of it. There can possibly be a leak in the fuel line that needs to be patched up. However, the fuel injector is another part that can cause fuel problems as it might have become old, which can lead to fuel becoming contaminated. A part that is called the mass airflow sensor can also be the problem, as it has to be in good shape to distribute fuel as it is designed.
