Vehicle Questions: Why is the Check Engine Light On?

Vehicle Questions: Why is the Check Engine Light On?

But some vehicle questions are too important to let them go unanswered. For instance, why is the check engine light coming on? Let’s find out.

Most of the time when you own a car or truck, you only know how to operate it. Maintenance issues might just go over your head, so you leave it to the professionals when it comes to making repairs or adding accessories. But some vehicle questions are too important to let them go unanswered. For instance, why is the check engine light coming on? Let’s find out.

The Gas Hatch Isn’t Secure

Once you finish refueling, you need to close both the gas hatch and the cap for the tank tightly enough. Luckily, you won’t need to get new parts or spend any money to resolve this issue. If you are currently driving, find someplace safe to pull over and then check both components to make sure they are closed and secure. If you had just gotten into your vehicle, you have a chance to double check as well.

Low Oxygen Warning

It might be trickier to answer any vehicle questions you may have when it comes to a low oxygen warning. The fuel for  your car or truck needs an adequate amount of oxygen in it. However, sometimes the sensors that oversee this element start to go haywire. Thus, it’ll take a toll on your overall gas mileage and fuel performance. Likewise, the fuel injectors help, and something could go wrong in there too. The mass air flow sensor has begun to malfunction and needs replacing. Your vehicle’s emissions will also suffer.

Check Your Catalytic Converter

Speaking of your vehicle’s emissions, you may have some more questions about that. Vehicle questions about the catalytic converter are nothing new. For instance, what does it do? It cuts down on the toxic fumes expelled through your vehicle’s exhaust systems. Many of the other smaller problems we are discussing here can sap the efficiency of your catalytic converter, and if you ignore these issues for too long, you will need a new converter unit. Unfortunately, that can get somewhat pricey if it needs to happen.

You Need New Spark Plugs

How old is your car? And if you drive a truck, how old is it? At some point, you will need new spark plugs. It could explain why your check engine light is on. If you don’t address this problem, it could affect your engine’s ignition system and prevent the car from starting.
