Many car owners don’t understand what it means when their check engine light comes on. If this is you right now, don’t worry! There’s actually a long list of reasons this particular dashboard warning can be activated. 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 yours may have activated.
Malfunctioning Spark Plug
One of the most common reasons the light comes on 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. Before taking your vehicle in, try tightening the gas cap. Sometimes that’s all it takes!
