It is important to not ignore the check engine light if it's on. While it may appear like an additional task on your list, the check engine light is an indication that there is something seriously not right. You don't want delay in addressing the issue.

Here are five common reasons your check engine light is on:

1. Gas Cap Issues

One of the most common causes is a leaky gas cap. It acts as a seal for the fuel system the gas cap helps maintain appropriate amounts of pressure inside the fuel tank. Additionally, it stops harmful fumes from being released. Take a look at https://www.motoradvices.com/ site if you need specifics resources about engine light.

This problem is among the cheapest and easiest to solve. If you notice that your check engine light coming on when you fill up with gas, check to make sure the gas cap isn't loose. It is easy to change the cap on your gas tank in your auto repair shop for $15.

You could lose fuel if you don't repair the cap on your gas. This will lead to more trips to gas stations.

2. It is important to replace the oxygen sensor.

The exhaust system of your vehicle measures the quantity of oxygen left unburned inside the vehicle using the oxygen sensor, or O2 sensor. The sensor transmits data to the computer in your vehicle, and the computer calculates the quantity of air and fuel that enters the engine pistons.

Even though a car is able to operate if the oxygen sensor is damaged but it's not recommended. If you ignore the issue, it could cause your engine to burn more fuel than it needs, you'll get fewer miles per gallon and other components such as the spark plugs or catalytic converter may be damaged.

3. You'll need a new Catalytic Converter

Catalytic converters can be a blessing to the environment and also to human health. Part of the vehicle's exhaust system they convert poisonous gas carbon monoxide into carbon dioxide.

Neglect is the main reason behind many catalytic converter problems. Regular maintenance, such as oil changes and addressing any issues that are displayed on the check engine light stop problems.

It is imperative to address the issue immediately. Your vehicle will not pass an emission test and may show a less performance or even fail in higher temperatures.

4. The Mass Airflow Sensor is bad

Part of the engine management system, the mass airflow (MAF) sensor keeps track of the air that enters the engine and determines the quantity of fuel needed for the engine to run efficiently.

How do you know if the MAF in your home needs to be replaced? The following are indicators of a malfunctioning MAF:

It's a rough idle

Problems that start

Throttle pedal's unexpected positional change

Poor mileage

Stalling

It is important to fix this problem as quickly as you can, since it could cause damages to the oxygen sensor, catalytic converter problems, or spark plug problems.

5. Spark Plugs Must Be Replaced

Spark plugs on vehicles ignite the engine cylinder's air mixture and fuel. If they're damaged, and not repaired in a timely manner they can cause larger issues like damage to the catalytic converter as well as the ignition coils, and the oxygen sensor.
