FAQ: Emissions Testing & Repair

McKonly's Garage Blog

Is your vehicle is due for an emissions test? While these tests are a normal part of every car and truck's life you may be curious what you are really in for. For your vehicle to be able to be legally licensed it must meet certain safety and emissions criteria that is regulated by the state government. If you have additional questions regarding these tests please contact your local emissions testing station.

Q. Where are emissions inspections completed?

A. All emissions testing must be completed at a certified testing center. These facilities must continually meet state generated criteria. These guidelines need to be met which include meeting equipment requirements, having proper personnel available to conduct the tests and checks and the facility must be able to properly process the appropriate paperwork and certifications.

Q. Will aftermarket auto parts affect the outcome of the emissions test?

A. In most circumstances all vehicles must retain the original emission equipment that was installed at the factory in order to pass the smog test. These parts include both sensors and mechanical parts, including:

  • PCV - positive crankcase ventilation
  • EVAP - evaporative emission
  • CAT - catalytic convertor
  • ACL - air cleaner
  • SPK - spark control
  • FR - fillpipe restrictor
  • O2S - oxygen sensor
  • AIS - secondary air injection
  • EGR - exhaust gas recirculation

Q. What parts are tested during an emissions test?

A. During emissions checks the car's emission system must pass a test showing that it is not producing excessive amounts of exhaust. This means examining the complete exhaust system for any issues, which may include testing the O2 (oxygen) sensor and catalytic converter to see if they are operating properly.
