Comprehensive Emissions Testing Services

What Our Emissions Testing Includes

Bob's Main Street Auto & Towing offers complete Wisconsin state emissions testing at our Hubertus location. Our certified testing process includes connecting advanced diagnostic equipment to your vehicle's OBD (On-Board Diagnostics) port to verify compliance with Wisconsin emissions standards. We check your vehicle's VIN, license plate information, gross vehicle weight rating for heavier vehicles, and electronic monitor status to ensure your car meets all state requirements.

Quick and Convenient Testing Process

Our emissions testing typically takes less than five minutes, with no appointment necessary. We operate on a first-come, first-served basis Monday through Friday from 8 AM to 5 PM at our Hubertus location. The process involves connecting diagnostic tools to verify that your vehicle's emissions control systems are functioning properly and that your check engine light is not indicating potential emissions failures.

State-Certified Testing Equipment

We use only Wisconsin Department of Transportation approved diagnostic equipment to ensure accurate results every time. Our state-of-the-art testing technology quickly identifies any issues with your vehicle's emissions systems, providing you with immediate results and any necessary documentation for vehicle registration renewal.

Wisconsin Emissions Testing Requirements

When Your Vehicle Needs Testing

Wisconsin requires emissions testing every two years for vehicles registered in seven counties: Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, and Waukesha. Vehicles manufactured in odd-numbered years are tested in even-numbered years, while vehicles from even-numbered model years are tested in odd-numbered years. Testing must be completed before license plate renewal beginning in the third year following your vehicle's model year.

Ownership Transfer Requirements

Vehicles changing ownership must undergo emissions testing if they are more than five model years old, within 45 days of ownership transfer. However, testing is not required if the vehicle passed an emissions test within 180 days before the transfer. Out-of-state vehicles more than five model years old must also be tested within 45 days of Wisconsin registration.

Compliance and Documentation

The Wisconsin Department of Transportation sends notifications by mail or email when testing is required. Our certified testing ensures your vehicle meets all state emissions standards, and we provide all necessary documentation for registration renewal. If your vehicle doesn't pass initially, our experienced technicians can diagnose and repair any issues to ensure compliance.

Common Emissions Testing Issues We Address

Check Engine Light Problems

A illuminated check engine light is the most common reason vehicles fail emissions testing. Our advanced diagnostic equipment quickly identifies the underlying issues causing check engine light activation, from faulty oxygen sensors to catalytic converter problems.

Emissions Control System Malfunctions

We diagnose and repair various emissions control system components, including catalytic converters, EGR valves, PCV systems, and evaporative emissions controls. Our technicians understand how these systems work together to reduce vehicle emissions and ensure compliance with Wisconsin standards.

OBD System Issues

On-Board Diagnostics systems must be functioning properly for emissions testing. We repair OBD communication problems, sensor malfunctions, and computer issues that prevent successful emissions testing.
