How Salt Lake County Emissions Testing Works
Salt Lake 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 Sandy?
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.

- Oxygen and air-fuel ratio sensors
- Catalytic converters (see muffler & exhaust)

- Ignition coils, spark plugs and misfire repair
- EGR valves and passages
- Exhaust leaks ahead of the oxygen sensors
Environmental Responsibility
The Salt Lake 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 Salt Lake County air cleaner and usually improves fuel economy too.
What Sandy Drivers Say
“Went in recently with what i thought would be at least $ 500 in repairs. walked out with a bill for only $ 70! Craig explained it was just a couple of brackets and a small length of exhaust pipe that needed replacing. and that my cat converter was probably ok. very honest & great staff!”
ZELMO62
“Great experience, had my car done quickly and helped me with emissions to get me back on the road when I needed it most. I appreciate the mechanics and what they do”
Bryan “Cal”
“Our catalytic converter was stolen. The folks here helped us locate one and have it installed in a matter of hours. So caring, so helpful, the epitome of great customer service.”
