WHAT DOES YOUR CHECK ENGINE LIGHT MEAN?
The Check Engine Light
When the check engine light comes on, it is immediately followed by two things. First, many of us begin to panic, and then we ask, “why”? There are many reasons why this happens, and some are common, while others are not. Understanding why your check engine light is coming on and the other indicators on the dashboard are essential. The experts from Kelsey Chevrolet can help resolve the issue, but here are ten reasons why it does happen.
Your Gas Cap Is Loose
One of the first things you should check if the engine light comes on is the gas cap. Vapors leaking from it can create confusion in the fuel system. For a quick fix, twist it tightly to see if that solves the issue. If it’s cracked, it’s an easy part that can be replaced rather inexpensively.
Bad Oxygen Sensor
Oxygen sensors can get compromised with a buildup of dirt and debris. As a result, it makes it more challenging to run your vehicle efficiently. More specifically, it decreases fuel efficiency quite a bit and could even damage other parts of the vehicle. You can determine when it’s time to replace it, according to the owner’s manual.
Although small, spark plugs play a vital role in accelerating and performance of the vehicle. It is true that replacing faulty spark plugs and wires is a reasonably simple job. However, most of the time, the issue comes when replacing them gets ignored. This situation leads to unnecessary problems that could have been avoided.
Your Battery is Starting To Weaken
The battery is seen by many as the lifeline of the vehicle. With a dead battery, your car won’t start. The good news is that modern batteries last longer than ever before. On average, you’ll get at least three years of lifespan from your car battery. Replacing a battery is an easy job that will save you the stress of getting stranded on the side of the road.
The Mass Air Flow Sensor
Mass air flow sensors regulate air that passes into the engine. Then, it helps to determine the correct fuel amount that should be used for smooth engine performance. Sometimes an air filter that has been installed incorrectly can create this to happen, but other times, it just needs to be replaced. You can go for several months with a broken sensor, but your car will end up stalling in the long-run.
The Catalytic Converter
The need to replace a catalytic converter is a more complex situation. It’s the part that is responsible for reducing harmful emissions into the atmosphere. Other than your engine light coming on, you’ll know there is a possible problem if you should notice a reduction in gas mileage or acceleration. Bring your vehicle in right away if you think it needs replacing.
Your car’s thermostat has a simple, yet important job. You already know the temperature outside fluctuates all year long depending on what time of the year it is. However, the temperature of your car’s engine is regulated with a thermostat. Ignoring it could cause your car to overheat and create significant engine damage.
Vacuum Hose Leak
If this issue occurs, you could also notice your car idling roughly and a hissing sound coming from near the engine. Over time, they get brittle and start to crack, but again, it’s a relatively simple fix. You shouldn’t drive with a vacuum leak because it can cause issues with your engine being as powerful as it needs to be.
Just like the battery, you need a properly working alternator for it to run properly. Working together, the car battery and alternator power the car’s electrical system. It’s necessary for powering everything from the interior lights to the HVAC system. You will also notice light inside your car starting to dim and the radio getting powered off.
Alarm systems provide the peace of mind we want for our vehicles, but they can also be a major headache if installed incorrectly. They can cause the battery’s power to get drained, which will create the engine light to kick on. This will also result in your alarm going off at unnecessary times, like when you’re trying to sleep!
