How Utah County Emissions Testing Works
Utah County requires an emissions test for most gasoline and diesel vehicles to renew registration. Your renewal notice tells you whether your vehicle needs one this year. Here’s what to expect:
- Bring your vehicle and registration renewal notice. The test is tied to your VIN and plate.
- We connect to your vehicle’s computer. On 1996 and newer vehicles, the test reads the on-board diagnostic (OBD-II) system and readiness monitors.
- Results are sent electronically. A pass is reported to the state so you can renew online.
- If it fails, we explain why. You’ll get the codes and our recommendation before any repair.
Common Reasons Vehicles Fail Emissions
These are the repairs we see most often after a failed test:
- Check engine light on
- Faulty oxygen sensors
- Failing catalytic converter
- Loose or damaged gas cap
- EVAP system leaks
- Engine misfires from plugs or coils
- Readiness monitors not set after a battery change
Tip: if you recently replaced the battery or cleared codes, drive normally for a few days before testing so the monitors can reset.
How Much Does Emissions Testing Cost in Orem?
Emissions test fees are set by the county, so the price depends on where your vehicle is registered. If your vehicle fails, repair cost depends on the cause: a gas cap or sensor is a small repair, while a catalytic converter is a bigger one. We always show you the codes and quote the repair before starting.
Need to spread out the cost? Master AutoTech offers several financing options, including the Goodyear Credit Card (6-month special financing on purchases of $250 or more), the Synchrony Car Care credit card, the 1stMILE Mastercard, Snap Finance, Acima, Surepay and RC Willey financing.
Emissions Repairs We Handle
- Oxygen and air-fuel ratio sensors
- Catalytic converters (see muffler & exhaust)
- EVAP purge and vent valves, hoses and gas caps
- Ignition coils, spark plugs and misfire repair
- EGR valves and passages
- Exhaust leaks ahead of the oxygen sensors
Environmental Responsibility
Utah Valley’s winter inversions trap pollution in the valley, and vehicle emissions are a big part of it. Keeping your vehicle in spec isn’t only a registration requirement; it helps keep Utah County air cleaner and usually improves fuel economy too.
What Orem Drivers Say
“Now I’ve been to a lot of mechanics and I mean a LOT of them. Master muffler is EASILY the greatest shop I have ever been to. Incredible service. Honest people. Quick work.”
Ammon Ridenour
“I took my van in last week with a couple of issues. This was the best experience I have had with them. They communicated very well. They were friendly and informative. They were easy to work with… Maybe one of the best experiences I have had with any mechanic.”
Jason McCune
“I’ve been taking all my vehicles here for the last 5 years or so. They always do an efficient job! You do not need to worry about dishonesty when it comes to these guys. After taking my car for oil changes elsewhere and getting screwed over I even take my car here for just oil changes. Thanks for the great work!”
