Have you failed an Emissions Test? We can help!


If you have been told that you need an emissions test and are looking for a place to get it done, you will need to take your vehicle to Air Care Colorado.  All emissions tests are performed by the state for Gasoline vehicles.

If you have failed an emissions test and need to have your vehicle repaired then call us at 303-290-9900.

Emissions failures are not very common anymore with modern vehicles that have onboard diagnostics computers.  If the vehicle has a check engine light on, it will likely fail the test.  If your check engine light is on then you should have it inspected before you attempt to get a test performed.  Most failures that are tied to a check engine light are relatively easy to diagnose and repair.  However there are times that a vehicle can fail without setting a warning light.  When this happens it becomes very difficult, time consuming, and usually expensive to repair. When this happens it is best to seek out an expert technician to look at and repair the problem.

Some common reasons for emissions test failures include but are not limited to:


  • Failed oxygen sensor
  • Failed air/fuel ratio sensor
  • Failed Catalytic converter
  • Plugged EGR system
  • Failed component in EGR system
  • High operating temperatures
  • Engine Misfire
  • Smoke from exhaust
  • Bad fuel cap

There are many other reasons that a vehicle might fail a test, however these are some of the more common.  Some have engine trouble codes that help indicate the problem, others do not.  If you have failed the emissions test and need help, don’t hesitate to call us at 303-290-9900.  You have a 10 day period to have the vehicle repaired and then retested without having to pay the $25 fee again.
