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 Provo?
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

- 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 Provo Drivers Say
“My brakes were making loud squeaking sounds. Some of it sounded like grinding. Decided to take it in to Master Muffler to get checked. EJ was friendly and helpful. They checked my brakes in 15-20 minutes and told me they still had a lot of life left, so they didn’t need replacing. They also loosened my oil filter that was jammed on tight. I didn’t have to pay a dime that day. Great mechanics that you can trust. Will be back for future services.”
Maka Chun
“My car broke down after a roadtrip. Took it into Master Muffler and they let me know I needed a new transmission and drive shaft. Vic was great to work with and handled talking to the warranty company to get the parts covered. I was able to get my vehicle back in 3 weeks and they did a great job! I will definitely be recommending them to me friends and family members!”
Judzia talbot
“Very pleased. I came as a first-time, walk-in customer for emissions testing and vehicle registration. There was no delay. The staff were professional and pleasant. The service was completed quickly. The waiting area and bathroom were as neat as a pin. Great job all around!”
