State Car Emissions Testing & Inspection

With normal car inspections and routine emissions checks, vehicle drivers can be familiarized with any mechanical issues with their cars. In case your vehicle failed to pass the inspection or the emissions test, you will know it is ready for some immediate attention and potentially some repair work. Vehicle owners should schedule the repair work ASAP because it might jeopardize the dependability of the vehicle and even cause substantial fines and even a disqualified registration. For that reason, it is highly recommended to have your car checked by a competent specialist at the very least every six months to avoid all these troubles. Some commonly asked questions on automobile inspection are described below.

What is On-Board Diagnostics or OBD?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system applied in all vehicles constructed in and after 1996. Basically, all the vehicles made in 1996 and after will certainly have an OBD system in them, which provides information records on self-diagnosis of the vehicle usually utilized by automotive service technicians prior to carrying out any automobile repair work.

What Are The Most Common Causes Of a Failed Emissions Test?

An emissions test can fail for numerous reasons because of malfunctioning car parts such as an injector, oxygen sensor, spark plugs or perhaps an EVAP system. One of the more common causes is faulty injectors. Either the injectors or a malfunctioning oxygen sensor can trigger a "rich air-fuel blend" bring about an unsatisfactory vehicle emissions test result.

If your automobile has worn-out spark plugs, there is a higher chance that it may be the source of an increase in exhaust discharges. This, subsequently, can lead to a failed vehicle-emissions test.

Any kind of problem or deficiencies in the EVAP system or evaporative exhaust control system can trigger an issue in the handling of the gasoline vapor discharged from the automobile leading to air pollution.

If your vehicle hasn't undergone routine maintenance and the "check engine" light is brightened on the dashboard, your car may not clear the emissions test.

What Do They Check for in a Vehicle Inspection?

An authorized examiner performs a car assessment at state-approved evaluation stations only. This is what they will look for:

  • Front lights: headlamps check to make sure of proper operation, no cracked lenses or lights, lights are the correct color, are the same, and turn signals are operable.
  • Tail lights: Turn signals, marker lights, hazard lights, license plate lights, brake lights, reverse lights are operable, and no broken taillights
  • Wheels and Tires: to check tire problems for any kind of signs of wear and tear and if there is a need for replacement
  • Mirrors: Make sure no mirrors are cracked, damaged or missing
  • Seat belts: to evaluate safety belt condition and make sure they are safely operating or need a replacement
  • Brakes: a thorough brake evaluation to ensure proper brake action and if there are any type of brake fluid leaks
  • Horn: ensure the horn is operative
  • Examination of suspension and shock absorbers
