Flatly, 1996 and newer cars cannot pass emissions testing with the “Check Engine” light on.

Emissions Test Arizona

Got my Honda’s emissions tested this weekend in Scottsdale.

I left the house just after 11 am on Saturday and headed over to the emissions testing location in Scottsdale (on Evans). I originally wondered if I’d encounter a long line, but then I remembered that Saturday afternoons, in the middle of the month, are the least busy.

This was the 13th, on a Saturday. I show up, and there’s about 3 cars ahead of me, so I waited patently for about 10 minutes before it was my turn.

Then it was my turn. I pulled into the drive-through garage, and turned off my engine, as instructed.

Next, I popped out of my car and they told me I could sit in the passenger seat, or sit in a little blue boxed-in waiting area (next to my car). I chose to wait in the blue box.

The entire emissions test only took about 10 minutes, and cost me $20 (I paid with VISA, but they also accept Master Card, American Express, Discover, and cash).

I will attempt to get some photos at some point of the process!

In case you are interested, here is what they give you as your receipt, and as verification that you have passed. I’ve blurred the parts that are relevant to me.

How to pass emissions test for car

If you’re about ready to get your car inspected for vehicle emissions, here are some helpful tips that will help your car pass the inspection.

Tips for passing emissions test:

  • Fast idle your engine for about 30 seconds immediately before you drive into the inspection facility.
  • Ensure your seatbelt is buckled (including all passengers).
  • Drive your car around for 10-15 minutes prior to entering emissions testing so it is at peak efficiency.
  • Turn off your air conditioning, heater, radio, or other accessories before the inspection starts.
  • Check your turn signals, lights, horn, and wipers before inspection and repair if they aren’t working.
  • If you have a engine maintenance light on, go and get that checked out by your mechanic before having the emissions tested.
  • Ask the DMV inspector for assistance or tips if you fail the inspection.

Emissions Test Waiver Locations in Arizona

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.

600 North 40th Street

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.
