Why Should You Take Your Car’s Upcoming Emission Test Seriously?

Millions of Americans get their emission test results each year. It is a necessary part of owning an automobile and is mandatory for new cars or older cars moving to a new city. According to the EPA, 31 states in the USA and the District of Columbia require emission tests. Thankfully, the test does not involve a lengthy regulatory process, and you can prepare your vehicle for it within a couple of hours. Failing is a cause for concern, but there are several tips you can follow to pass an emission test. 

All kinds of engines give off emissions, and these can include significant amounts of carbon dioxide, carbon monoxide, and other volatile hydrocarbons. In individual states, vehicles can only produce a certain amount of byproducts (emissions) at a time. Every car has a federal standard, and the presence of onboard diagnostic ports help technicians monitor the management systems. These technicians keep an eye on the monitors to check the cycles of the different systems in place. The presence of diagnostic II ports inside modern automobiles has made emissions testing a lot easier than before. 

Why do cars fail emission test?

The regulation on OBD II requirement in 1996 was not uniform, and several older models lack this port. Models prior to 1996 require the old treadmill test. Only a few facilities perform these tests, but in most states, the older cars do not have to undergo emission tests at all. However, if you have appeared for this test and failed, you might need to consider the following possibilities:

  • It is a critical mechanical problem or engine error.
  • It can cost hundreds or thousands to repair.
  • It can be something as simple as a misfit gas cap.

The cost of failing an emission test can range from $17 to $1200. In some of the worst-case scenarios, the problem persists in the form of a cylinder that cannot hold the compression or a spark plug in the engine that has stopped working.

Unless you are an expert, you might find it impossible to tell what factors may have contributed to high emission levels. 

What to do if you have already failed the emission test? 

If you have failed a test and the reason turns out to be more severe than a faulty gas-cap, you should consult an experienced mechanic. Some of them might even have the diagnostic tool that can pinpoint the precise problem in your car. However, these tools do not provide the solution to your question. That is why you need to take your car to an experienced mechanic, who has possibly tackled several similar problems in the past. You should ideally take your vehicle for a thorough inspection in case the check engine light comes up before the emissions test. Several automotive experts believe that the light only comes on for emission related issues.
