Why Is My Check Engine Light On?

check engine lightMany car owners have little to no understanding of what it means when their check engine light comes on. If this is you right now, don’t worry! There is actually a long list of reasons this particular dashboard warning has activated. Knowing what the problem is right away isn’t always feasible. In fact, you’ll probably need to take your vehicle to a nearby auto service center to identify the issue. Luckily, it doesn’t take long for an auto technician to run an engine diagnostic that will pinpoint the exact cause. In the meantime, here are a few of the most common reasons your check engine light may have activated.

Malfunctioning Spark Plug

One of the most common reasons that your check engine light might activate is a problem with a spark plug. When this happens, the light will probably be accompanied by problems starting your vehicle. You’ll need to schedule an appointment with an auto repair specialist to have the spark plug replaced.

Broken Catalytic Converter

Another possibility is that your catalytic converter needs to be replaced. This part is responsible for minimizing the impact your vehicle has on the environment. Taking care of emissions issues is extremely important, so go in for car or truck repair right away.

Lost or Damaged Gas Cap

While this might seem like a small problem, a lost or damaged gas cap can cause your check engine light to activate. Fortunately, this is a quick fix, but it’s also one you want to take care of right away. Continuing to drive without one can negatively impact the environment and your mileage.
