Muffler, Exhaust, Emissions | Virginia Auto Service


Virginia Auto Service is located in Phoenix is an Arizona Certified Emissions Specialist. Most people see emissions testing as something annoying that simply needs to be done every once in a while. Although this is accurate, it is always helpful to address a few questions most of us would like answered regarding the Emissions Standards Test in order to avoid the feared P0420 or PO420 codes generated by their check engine light.

Why is it important to have car emissions measured and adjusted?

Since the 1950’s, government agencies down to the state level have been monitoring the emission of noxious gases from automobiles. As time continued, tests regarding high vehicle emissions were conducted and proved that emissions had adverse effects not only on humans, but the environment as well. Medical tests have shown that high levels of hydrocarbons, carbon monoxide, soot, and smoke, even at microscopic size, can lead to illnesses. In high doses, these gases can lead to liver failure and in extreme cases, even death.

Since when is it a law that emissions should be checked and regulated?

Because it was highly ineffective to regulate emissions from a state and local level, control of the emissions standards nationwide were slowly put into the care of Federal systems. In the 1970’s, the United States Environmental Protection Agency, better known as the EPA, was created. Since that time, the EPA imposed strict limitations to keep the emission of noxious gases maintained at a minimum.

What needs to be done in order to pass?

Honestly, the best way to make sure that you’ll pass the emissions test the first time around is preventative maintenance. An engine that is well taken care of has a much better chance of breezing through the emissions test. But in case you’ve neglected the engine a bit, here are a few things that Virginia Auto Service can do for you to better your odds.
