Subaru Check Engine Light

It can be alarming to notice your check engine light has turned on, and you may wonder what it means and whether it's because of an issue with your vehicle. There are a variety of things that may cause this light to turn on, and it's important to understand the possible causes so you know when to bring your car to a mechanic. Here's a look at some of the reasons it may illuminate, and when it means there's a serious issue with your vehicle. 

What Could Cause a Check Engine Light To Come On?

There are several reasons why your car's check engine light may turn on. Familiarizing yourself with why this can happen can help you save time and money by knowing when to bring it in to a mechanic. Here's an overview of the reasons this light may turn on in your vehicle:

You have a loose or detached fuel cap

If you forgot to put your fuel cap back on while filling up at the pump, or you didn't screw it on correctly, your check engine light may turn on. Fortunately, this issue has an easy solution that you can take care of without visiting a mechanic. This is a common reason for check engine lights to turn on, so you'll want to check your fuel cap before worrying that other issues are going on with your vehicle. 

Your vehicle is having emissions issues

Another common reason for a check engine light to turn on is if the vehicle is having emission or exhaust system issues. There may be a problem with the car's catalytic converter, the mass airflow sensor (MAS), or there could be an exhaust leak. When you notice the check engine light turn on, it's a good idea to have the exhaust system inspected by a technician to identify and repair any issues. 

There's a problem with an oxygen sensor

If your vehicle's check engine light turns on, it may be because there's a problem with an oxygen sensor in the car's emissions system. These sensors can detect exhaust issues, and if the check engine light is on, it may indicate that there's a problem with your exhaust. It also may show that one of the sensors is giving a faulty reading, and requires a repair or replacement.

You should check your car's wiring

Issues with your car's wiring may also cause the check engine light to turn on. There are several wiring systems within your vehicle, including its battery, ignition system, and spark plug wires. It's essential for these wires to function properly to ensure you can rely on your vehicle and stay safe on the road. A loose connection or damaged wire may cause your check engine light to illuminate, and requires attention from a service technician. 

You're due for an oil change

If your vehicle is low on oil or the oil in your car is contaminated with dirt and debris, your check engine light may turn on. These issues can lead to poor engine performance and other engine problems later on. By visiting a service center, you can have a technician take a look at the engine and its oil. They'll let you know if you're just due for an oil change or if there's a more serious issue going on. 

Is It Okay To Drive With the Check Engine Light On?

Since your check engine light may indicate a wide range of issues, it's important to take your vehicle to a mechanic when you notice the light illuminated. Unless you're able to identify and resolve the issue quickly, like screwing on your fuel cap correctly, it's hard to tell why the light turned on, and whether it's because of a serious issue. 

If you notice other performance issues, make sure to take it easy and visit a mechanic as soon as you can. While it may not be a serious issue, the safest option is to avoid driving with the check engine light on, and make a service appointment when you notice it.

How Do I Know if My Check Engine Light Is Serious?

It's hard to tell whether your check engine light indicates a serious repair or a quick fix. Sometimes, you'll notice other important indicators in addition to the check engine light. For example, you may notice it illuminated along with the temperature warning lights and gauges that suggest your car is overheating. However, just because the check engine light is the only indication of a problem doesn't mean you should take it lightly. 

Should I Go to a Mechanic if My Check Engine Light Is On?

When your vehicle's check engine light turns on, it's a good idea to visit a mechanic and have them take a look at it. Since the check engine light can be an indicator of a variety of problems and maintenance needs, it's better to have a technician review it rather than trying to figure it out yourself.
