How Frequently Do I Need an Emissions Test?

The answer is that you will be required to have each of your vehicles inspected once every two years.

When you receive your DMV renewal from the state they will indicate whether you are required to have your car tested for emissions. If so, you normally have a month or two to get it done.

Renewal of DMV fees can be done in person or at the DMV.

Which vehicles are exempt from the testing requirements?

  • Most model year 2007 or newer, except reconstructed, vehicles
  • Most model year 2009 or newer original equipment alternative fuel vehicles
  • Model year 1966 and older vehicles
  • Vehicles designated as “collectible” (requires collectible vehicle insurance, reported to Arizona Motor Vehicle Division by insurer)
  • Electric powered, golf carts or vehicles with engine displacement of less than 90cc
  • Motorcycles registered in the Tucson metropolitan area
  • Apportioned vehicles (licensed in more than one state)
  • Vehicles leased to a person residing outside the emission control areas
  • Vehicles transferred between dealers (wholesale)

Emissions Test Waiver Locations in Arizona

If you have had your emissions test fail at least two times, you may qualify for a waiver.

You’ll need to demonstrate that sufficient effort and costs were incurred in an effort to repair your vehicle. See the price table here. There is a $15 fee for the waiver. Save all of your repair receipts. Once a waiver has been granted that vehicle may never receive another. Therefore, you’ll probably need to eventually get it repaired.

Waiver facilities are open 8:00 am to 4:30 pm, Monday through Friday, except for all major state holidays. There are two locations in Arizona, and they are:

600 North 40th Street
Phoenix, Arizona 85008

4040 East 29th Street
Tucson, Arizona 85711

Good luck on your vehicle inspection!

What should I do if my car fails the emissions test

If your vehicle has failed an emissions test at an Arizona facility, they’ll usually give you some indication about why it has failed. You can take that information and provide it to any mechanic and with any luck they will be able to make some repairs to your vehicle. You can take a free-retest after you complete your repairs.

Why do I need emissions test in Arizona? The reason is because Arizona is one of the fastest growing states in the country and because of the mountains surrounding our cities (especially Phoenix) air pollution tends to settle in the valleys. This creates a smog build up that is visible in the air. What happened was that the Motor Vehicle Division (MVD) partnered with the Arizona Department of Environmental Quality (ADEQ) to administer a program they dubbed Car Care. The program is designed to control emissions and reduce pollution in the air. Arizona risks losing millions of dollars in federal highway funds if they don’t participate in the Clean Air Act, a federal program.

There are 31 states that require vehicle-emissions testing. Of those, 9 operate like Arizona with locations centralized. Other states allow independent auto-repair shops to check emissions. One reason Arizona doesn’t allow independent auto-shops to test is because we have more stringent standards. Arizona tests older vehicles (1967 to 1995 models) on the dynamometer rolling system. This system is too expensive for most auto shops to install.

Data from 2011 shows that only 6.3% of 2006 model vehicles failed the initial emissions test. Older cars made between 1967 and 1977 had higher failure rates usually between 32-43% (that’s high!). Here’s a great article from The Arizona Republic about the emissions testing program.

More than 90% of newer vehicles pass the test on the first run (about 1.3 million Arizonans a year).

First, the good news! You’re car re-inspection is free (as long as you return within 60 days) and you complete the repair information notes (reverse side of the original vehicle inspection report).

If your vehicle fails the emissions test two or more times and you have made reasonable attempts to repair it, then you may qualify for a waiver.

Some common reasons for a smog check failure include:

HC – Hydrocarbon faults:

  • Incorrect ignition timing
  • Faulty spark plugs and/or wires
  • Lean fuel mixtures
  • Vacuum leaks
  • Low cylinder compression

CO – Carbon Monoxide faults:

  • Faulty oxygen sensor(s)
  • Defective MAP sensor
  • Defective TPS sensor
  • Defective ECT sensor
  • Faulty fuel injection/carburetor

NOx – Nitrous Oxide faults:

  • Defective EGR system
  • Lean fuel mixtures
  • Overheating engine
  • High cylinder compression
  • Defective catalytic converter

Note: The possibilities listed above vary based on your vehicles make and model. Some times a vehicle can fail based on something entirely different. Always do a hands on diagnosis and speak with a qualified mechanic.

If the check-engine light is on, you’ll most likely want to check that out with your mechanic prior to getting your emissions test done. The folks at ADEQ actually recommend getting a check-engine light looked at prior to testing since it is likely to fail.

Here is a wonderful article that provides an overview of what you can do to pass an emissions test if your car had previously failed.
