When your vehicle’s check engine light shows up, it can be alarming. With a variety of components in your engine, many different things can cause the check engine light to go off. However, it is difficult to determine what exactly is going on with your vehicle simply by looking at a light. If you are ever unsure about a noise, sound, light, etc. that is unfamiliar, please feel free to contact a member of our team at either our Exton, PA or West Chester, PA locations.
