If you’re like most drivers, you probably pay little attention to your car’s check engine light. But if the light is on, there’s a good chance that your car has some major problems that need to be fixed.
What Causes an Emissions Check Engine Light?
If you are like most drivers, you probably don’t give much thought to your car’s emissions. You may know that you need to get your car tuned up from time to time, but that’s about it.
Well, the truth is that your car’s emissions can be a major safety concern. In fact, if your car has an emission check engine light on, it could mean that there is something wrong with the engine.
In this article, we will discuss what causes an emission check engine light and what you can do to fix it. We will also provide some tips for keeping your car’s emissions in check.
What to Do If You Have an Emissions Check Engine Light
If you have an emissions check engine light on in your car, there are a few things you can do to try and fix the issue. First, make sure you know what the code means. Many times, a code that appears on your car’s computer is just temporary and will go away after a while. However, there are some cases where the code might mean that your car needs repairs. If you’re not sure whether or not your car needs repairs, then you should take it to a mechanic to get an accurate diagnosis.
If your car does need repairs, then you’ll need to take it to a mechanic. However, before you do that, you’ll want to try and fix the issue yourself first. Here are a few tips on how to do that:
1) Make sure all of your airbags are off and all of your doors are closed while your car is running. This will help reduce the amount of air pollution that gets into your car.
2) Change your air filter – this will help reduce the amount of dirt and dust that gets into your engine.
3) Change your oil – this will help reduce the amount of wear and tear on your engine.
How to Fix an Emissions Check Engine Light
If your car’s check engine light is on, there’s a good chance you have one or more emission problems. In this article, we’ll show you how to fix a check engine light with simple steps.
First, check the air filter. If it’s dirty, replace it. Dirty air filters can cause emissions problems.
If the car has an automatic transmission, make sure the gear shifter is in Park and turn the key to the off position. Then disconnect the battery cable. This will keep any computer settings from being affected when you do repairs.
Next, remove the spark plugs. You may need to use a wrench to do this because they are covered with electrode caps and wire bands. Be careful not to damage the plug wires. Once the plugs are out, clean them with a solvent and brush. Use a new spark plug if needed.
To test for emissions problems, connect a digital exhaust gas analyzer (EGA) to the car’s intake manifold using an OBD-II scan tool. The tool will show you the severity of your emissions problem and what needs to be done to fix it.
Conclusion
A car with a check engine light on is usually an indication that there is something wrong with the emissions system. If you’re not sure whether your car will pass emissions, it’s best to take it in for an inspection. While most problems can be fixed without any expensive repairs, fixing them can add hundreds of dollars to the cost of your car ownership.
