These common indicators can affect results. If you notice any of the following, we can help diagnose issues before testing.
Any active malfunction indicator lamp (MIL) or stored emissions codes will cause an automatic failure.
Readiness monitors reset after battery disconnects or module resets; drive normally so they can complete before testing.
A loose or faulty gas cap and EVAP leaks are frequent causes of failed readiness or stored codes.
Insufficient drive time or missing drive cycles can keep monitors from setting, leading to a test rejection.
Missing or altered emissions equipment may prevent passing and must be addressed before testing.
Engine performance issues increase emissions and can cause test failures.
We offer quick, professional inspections with clear results. If your vehicle needs repairs, we can help with diagnostics and estimates.
