From oil changes and tire rotations to washing the exterior and adding windshield wiper fluid, maintaining a vehicle can become overwhelming at times. Unfortunately, even with proper maintenance, your vehicle may experience issues that affect its operation and value. If you notice your check engine light has come on, you may feel a great sense of dread, but help is available. Here are a few common reasons why your check engine light may come on.
Loose/Faulty Gas Cap
You may be surprised to learn your check engine light may illuminate for something as simple as a loose gas cap. The cap is essential for many reasons. Not only does it help block the interior of your gas tank from dirt, dust, and other debris, but the cap also acts as a seal, blocking and trapping vapors to ensure they do not flow out into the environment.
If the gas cap is loose or the threading is worn down, there will not be a strong enough seal. This can lead to vapors leaking, harming the environment, and causing your vehicle's computer system to detect the leak, displaying the check engine light on your dashboard.
Failing Catalytic Converter
Another common reason why your check engine light may be coming on is if there is an issue with your catalytic converter. This important part of the vehicle's exhaust system turns carbon monoxide into carbon dioxide, ensuring your vehicle functions in the most effective, efficient, and safe manner possible.
You can reduce your risk of catalytic converter failure by performing regular oil changes on your vehicle. If you notice flumes of smoke flowing out of the exhaust or smell unusual smells, have your engine and catalytic converter checked by professionals.
Spark Plug Issues
If your check engine light is on, consider inspecting your spark plugs and spark plug wires for signs of distress. Without properly secure spark plugs, the fuel and air will not ignite the cylinders to start your engine.
Make sure there are no visible signs of corrosion around your spark plugs and wire connections. Also, check the wires to ensure they are securely connected to the spark plugs. If your vehicle is idling roughly or you are noticing a decrease in fuel efficiency, you may need to replace all your spark plugs.
A check engine light does not have to induce fear or panic. However, your vehicle should be evaluated by professional auto technicians. Contact a car repair service like Suburban Driveline Inc for more information.
After struggling for years with a terrible car, I knew that it wasn't going to last another season. It was beat up, worn out, and completely unreliable. Instead of giving up on the car, I decided to talk with a friend of mine who was really great with vehicles. We worked together to take care of things, and we even found some great prices on auto parts to take care of business. When we were finished, the car ran like new, and I was really impressed with the results.
