Texas Vehicle State Inspection & Emissions Testing – Everything You Need to Know

Your Trusted Texas Emissions Testing Center in Houston, TX

If your vehicle is registered in Texas, you’re required to pass an annual vehicle inspection before renewing your registration. In certain counties – including Harris County – that inspection includes emissions testing to help keep our air clean and meet state and federal environmental standards.

At Faith Auto Repair in Houston, TX, we specialize in Texas vehicle state emissions inspections. We no longer provide safety inspections – our focus is fast, accurate, and certified emissions testing so you can renew your registration without delays.

What is the Texas Vehicle Emissions Test?

The Texas Department of Public Safety (DPS) requires emissions testing in designated counties to ensure vehicles meet clean air requirements. If your vehicle fails, you must have repairs completed and pass a retest before registration renewal.

We provide state-certified emissions inspections for:

Passenger cars

Light trucks & SUVs

Vans

Motorcycles (emissions testing not required for motorcycles, but safety inspections apply in other facilities)

Who Needs Emissions Testing in Texas?

If you live in one of Texas’ 17 emissions counties – including Harris, Fort Bend, Brazoria, Montgomery, Galveston, and Waller – you must pass an emissions test each year before renewing your vehicle registration.

You need emissions testing if your vehicle:

Is 2–24 years old (newer vehicles are exempt for the first two years)

Runs on gasoline or diesel (diesel vehicles have different requirements)

Is registered in a county that participates in the emissions program

Types of Texas Emissions Tests We Perform

We use state-approved emissions testing equipment to check your vehicle based on its model year and type:

OBDII (On-Board Diagnostics) Testing – For 1996 and newer vehicles, we plug into your car’s computer to check emissions-related trouble codes.

ASM (Acceleration Simulation Mode) Test – For some older vehicles, we measure exhaust emissions while your car is on a dynamometer.

Two-Speed Idle Test – For older or specialty vehicles without OBDII systems.

How the Texas Emissions Test Works

When you visit Faith Auto Repair for emissions testing:

We verify your vehicle information in the state system.

We connect to your vehicle’s OBDII port (or use other required testing methods).

We check for emission system readiness and look for trouble codes.

We provide your results instantly – pass or fail.

If you pass, we upload your results to the state database immediately so you can renew your registration online or at your local tax office.

What Happens If You Fail the Emissions Test?
