Vehicles are equipped with computers to monitor the important systems in your car and alert you if something is wrong. The check engine light is the first sign that there could be a problem and that you should seek service as soon as possible.
There are many reasons that a check engine light might activate. It could be as simple as a gas cap that is loose or something much more serious like a bad catalytic convertor. Given that there are so many possibilities that could cause your engine light to come on, it’s best to have your car checked out at your earliest convenience. Below you will find a list of some of the issues that could be causing your engine light to activate:
• Loose gas cap
• Problem with the MAF sensor or circuit
• System running too lean or too rich
• Cylinder misfire
• Knock sensor circuit malfunction
• Insufficient EGR (Exhaust Gas Recirculation) flow
• Catalyst system efficiency below threshold
• Faulty oxygen sensor
