I think we’ve all experienced that sinking feeling. You’re driving along, going about your day, when you notice your car’s check engine light come on. At this point you don’t know if it’s due to something minor or if a costly repair is looming on the horizon. Unless your car is stalling or the engine is starting to smoke, you likely have a window of time to get home and make an appointment with your mechanic. One thing that you shouldn’t do, however, is ignore the check engine light in hopes that it will go away on its own. Doing so could wind up costing you more in the long in run, and may even put you and your family in danger while on the road. The only real way to find out what is going on with your car when the check engine light is on is a diagnostic test. However, there are a few common issues that can cause the check engine light to come on. Take heart, it’s usually not something that will break the bank to fix. Below is a list of possible reasons for your check engine light to come and what can be done to fix the problem.

Loose or faulty gas cap

This is by far the easiest fix you could hope for. If your gas cap isn’t screwed on properly, or is cracked or broken, it can cause emissions to escape and will knock off the car’s fuel system pressure. If your check engine light has come on after you filled up, this is a likely cause. Tighten up or replace your gas cap, if it’s broken.

Worn-out spark plugs or spark plug wires

Your spark plugs are responsible for transferring electricity from the ignition coil(s) and use it to ignite the air/fuel mixture in the combustion chamber.spark plugs are essential for keeping your car running. If your spark plugs have gone bad, it could cause a “rumble” in the engine or problems starting your car. Fortunately, replacing your spark plugs isn’t a very costly repair. A new pair of spark plugs can be bought for under $50, plus additional costs for labor.

Catalytic converter

A catalytic converter is an emissions control device in your car’s exhaust system. It turns harmful gases like carbon monoxide generated during the combustion process into carbon dioxide. It’s a fairly simple part, but it is necessary for it to be functioning properly. If your car’s catalytic converter is faulty, it will cause the check engine light to go on. A new converter can be purchased for roughly $500, plus labor.

Your car’s battery

If your car’s battery is dying, you’ll likely notice difficulty in starting your car in addition to the check engine light coming on. If this is the case, grab some jumper cables and get someone to give you a boost. Make your way to your local mechanic for a replacement battery. This shouldn’t cost more than $300 to fix.

Mass Airflow Sensor is faulty

The mass airflow sensor determines the mass of air entering a vehicle’s fuel injection engine, This is necessary to correctly balance and deliver the correct amount of fuel to the engine. If your vehicle’s mass airflow sensor is faulty, you may find your car stalls or has difficulty starting. Replacing a mass airflow sensor shouldn’t set you back more than a thousand dollars, at most.
