Before you come in
Four things that help you pass.
Drive it 15 minutes first
A warm engine and hot catalytic converter burn cleaner. A cold start can fail a test it would otherwise pass.
Check engine light off
An illuminated check engine light is an automatic fail on any OBD-II vehicle. No exceptions.
Fix known issues first
A failed test goes on the record and follows the vehicle. Repair before you test.
Don't tamper with emissions gear
Missing or modified emissions components fail on the visual inspection, before the analyzer runs.
