Failed Emissions Repair

Failed emissions test repair in Winthrop Harbor

Quick answer

If your car failed its emissions test, Wenzel's Automotive in Winthrop Harbor finds and repairs the fault so it can pass the retest. All of Lake County, Illinois is in the state emissions testing area, and Kenosha County, Wisconsin has its own inspection program. We diagnose and repair the fault so the car is ready for the state retest.

What is included

  • Review of your failed test report
  • Diagnosis of the stored emissions codes
  • Repair of sensors, evaporative system leaks, misfires and exhaust parts
  • Readiness monitor check so the car is ready for the retest

Signs you need it

  • A failed test notice or report
  • The check engine light is on before your test is due
  • The battery was recently disconnected and the car is not ready
  • A gas cap or evaporative system warning

Illinois testing in Lake County

Illinois tests most 1996 and newer gasoline cars and light trucks once they are four years old, on a two-year cycle tied to the plate renewal. The test reads the car's onboard computer. A lit check engine light or monitors that are not ready will fail it. The Illinois Air Team station closest to us is in Waukegan at 2161 Northwestern Avenue, according to the Illinois EPA.

Drivers from Kenosha County

Kenosha County is part of the Wisconsin Vehicle Inspection Program. The same idea applies: if your car fails because of a stored fault, we can diagnose and repair it here, then you return to the Wisconsin program for the retest.

Failed Emissions Repair questions

Where do I take the retest after a repair?

In Illinois, at an Illinois Air Team test station; in Wisconsin, through the Wisconsin Vehicle Inspection Program. We repair the fault and tell you when the car is ready for the retest.

Why did my car fail if it runs fine?

The test reads the onboard computer. A stored fault, an evaporative leak too small to notice, or readiness monitors that have not finished after a battery change can all cause a failure on a car that drives normally.

How soon can I retest after a repair?

The car's readiness monitors need to complete after a repair, which usually takes some normal driving. We tell you when the car is ready.
