Utah Emissions Inspections at Master Muffler Ogden

If you live in Weber County, Utah State Law requires that you have an emissions test performed every 2 years for vehicles that are less than 6 years old. Vehicles with odd model years do not require emissions tests in odd years, and vehicles with even model years do not require them in even years. Emissions inspections must be performed no more than two months before you renew your vehicle’s registration. Emission certificates must be submitted to the appropriate DMV office to complete registration.

The Importance of Emission Inspections

It may not seem like it, but emissions tests are incredibly important. Motor vehicles are one of the leading causes of air pollution. Cars can release pollutants such as hydrocarbons and carbon monoxide into the air. To combat this the Environmental Protection Agency put strict emissions standards in place to keep tailpipe emissions under control. Following these guidelines is important for reducing the negative impact vehicles have on the environment and helping to improve the air quality.

How Your Vehicle’s Emissions are Tested

Every vehicle’s engine gives off emissions, so to lower the number of pollutants released the EPA put new regulations into place. These regulations include emission inspections and creating guidelines for vehicle manufacturers to follow when designing new vehicles. Emission tests ensure that your vehicle is not releasing more pollutants than allowed by the EPA. Early versions of the emissions test required cars to be placed on a kind of treadmill for vehicles known as a dynamometer. Testing equipment was then hooked up to the tailpipes to monitor the number of emissions released by your vehicle’s tailpipe. Nowadays the test is a lot simpler. Vehicles with model years from 1996 and newer may be hooked up to a diagnostic device. Mechanics may also perform a visual inspection of your car’s exhaust. There is another version of the inspection that requires testing on a sample of the air coming from your tailpipe. All of these tests help give your vehicle a pass or fail grade during your emissions inspection.

  • If you pass your inspection, you are free to register your vehicle. If you fail, you may need to have repairs performed on your vehicle to help it pass the inspection.

There are a few reasons why your car may have failed the test. There could be issues with your vehicle’s catalytic converter, ignition timing, fuel system, or exhaust gas recirculation. Contaminated engine oil can also cause your vehicle to fail. The cause could also be as simple as a loose gas cap. Your mechanic will be able to help diagnose the issue so you can figure out how to repair it.

  • If you failed your inspection, there is no reason to consider getting a second opinion. The testing procedure is absolutely reliable.

Signs To Watch For

If your check engine light is on, your car will not pass inspection. Vehicles with the check engine light on can release over 100 times the amount of pollutants than cars that are running properly. Before doing any testing, any issues involving the check engine light must be addressed. If your check engine light is on, our full-service shop can quickly diagnose the problem and repair it for you, before performing the state inspection.
