If you have to take your vehicle in for an emissions test, and you are worried that for some reason your vehicle will not pass the emission tests, there are a few things that you can do to make sure that your vehicle is ready for the emissions test.

Make Sure You Have a Gas Cap

First, when you go to your emissions test, the inspectors are going to make sure that you have a gas cap. They are going to make sure that the gas ca is securely tightened on your vehicle. If you don't have a gas cap, you can pick one up for very little money at your local auto parts store. A generic gas cap should easily fit over your gas outlet on your vehicle.

Make Sure Your Check Engine Light is Off

Second, you need to make sure that your check engine light is off. Your check engine light being on is one of the biggest reasons that you will fail your emissions test. If your check engine light is on, you need to head to your local emission test repair shop and have the codes from your engine read. This will let you know what you need to fix on your vehicle.

Your check engine light can come on for a variety of different reasons. Your check engine light can be triggered by something as simple as a loose gap cap, failed oxygen sensor, catalytic converter failure, or an old spark plug. Just because your check engine light is on doesn't mean that the repair is going to be expensive.

Fixing your check engine light is a good idea not just for your emissions test, but for the overall health and well-being of your vehicle. Fixing the check engine light issues will fix issues that are hampering the performance of your vehicle. Oftentimes, fixing the issues brought up by the check engine light will prevent bigger issues with your vehicle. Your check engine light lets you know about the little things that are wrong with your vehicle, so that bigger issues don't come up.

Drive Around Before Heading to the Test

Don't just go straight to the emissions test. When you go to the emissions test, they are going to read the information from the emission control system diagnostics mechanism. Your emission control systems generates this information and runs self-tests after you have driven your vehicle for a specific amount of mileage, so if you only drive a couple of miles before going to get your emission check, your vehicle may not have time to generate the necessary date.

Make sure that your vehicle is nice and warmed up, the check engine light is off, and your gas cap is on tight before you head over to take your state-mandated emission control test.
