Emission Components & Failures

If you do not pass your Colorado emissions test, we can handle it!

Since an emissions test is required on virtually all but the oldest of vehicles we can perform any of the required service and/or necessary repairs to get you and your vehicle “passed” and on the road again.

WHAT IS THE EMISSION SYSTEM?

Your vehicle’s emission system keeps the engine running cleanly and efficiently in all sorts of operating conditions. Usually when the system is out of sync, running poorly, needing service or repairs, the check engine light on the dash comes on and indicates there’s something out of tolerance in the emissions system.

A steady or flashing warning light on your vehicles dashboard usually indicates a problem that is currently happening and may require immediate attention. Failure to have an issue addressed promptly can affect your vehicle’s performance: reduce your gas mileage, acceleration, and cause other drivability issues. It can also cause your vehicle to pollute more than it should. Or more than is allowed by our state’s air quality standards. That’s one reason that periodic emissions tests in Colorado are required—to keep our air as clean as we can for us and future generations.

WHAT DOES IT DO?

Your car’s emission system controls the emissions, exhaust and pollutants (including gasoline vapors escaping from the fuel tank), using an array of sensors, computerized engine controls and the exhaust components. The emission system substantially reduces harmful gases such as carbon monoxide (CO), unburned hydrocarbons (HC) and oxides of nitrogen (NOx) and, by law, must be maintained in operating condition.

Some wear and tear factors that can negatively affect the vehicle’s emission system include:

  • Driving and atmospheric conditions
  • Mileage
  • Vehicles age
  • Type of spark plug electrode material
  • Poor vehicle maintenance
  • Poor quality fuel
  • Damaged or worn sensors
  • Dry-rotted or cracked vacuum hoses
