State Vehicle Inspection & Emissions Testing

With routine vehicle inspections and routine emissions checks, vehicle drivers can be familiarized with any mechanical issues with their cars. In case your car fails the inspection or the vehicle-emissions test, you will definitely know it is ready for some immediate attention and potentially some repair work. Car owners must make plans for the repair ASAP because it might endanger the dependability of the car and also result in significant fines or perhaps an invalidated registration. Therefore, it is always advised to have your car inspected by a competent specialist a minimum of every six months to avoid all these troubles. Some commonly asked inquiries on automobile inspection are described below.


What is On-Board Diagnostics?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system applied in all automobiles built in and after 1996. Basically, all the automobiles made in 1996 and after will have an OBD system in them, which provides information reports on self-diagnosis of the vehicle often utilized by automobile technicians before doing any vehicle repair work.


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

A car emissions examination can fail for several reasons as a result of malfunctioning vehicle parts such as an injector, oxygen sensing unit, ignition system and even an EVAP system. The most common cause is defective injectors. Either the injectors or a malfunctioning oxygen sensing unit can set off a “rich air-fuel combination” resulting in an unsatisfactory vehicle emissions test.

If your vehicle has a damaged ignition system, there is a higher possibility that it might be the root cause of a boost in exhaust discharges. This, consequently, can lead to a failed vehicle-emissions test.

Any type of issue or deficiencies in the EVAP system or evaporative emission control system can trigger a trouble in the handling of the gas vapor produced from the vehicle leading to air pollution.

If your car hasn’t gone through regular maintenance and the “check engine” light is brightened on the control panel, your automobile might not clear the vehicle-emissions test.


What Do They Check for in a Vehicle Inspection?

A licensed examiner performs an automobile inspection at state-approved assessment stations only. This is what they will check for:

  • Headlights: headlamps evaluation to make sure of proper operation, no cracked lenses or lights, lights are the correct shade, 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
  • Tires and Tires: to check tire problems for any kind of indications of wear and tear and if there is a need for replacement
  • Mirrors: Ensure no mirrors are broken, damaged or missing
  • Seat belts: to analyze safety belt condition and make sure they are securely operating or need a replacement
  • Brakes: a comprehensive brake inspection to ensure proper brake reaction and if there are any type of brake fluid leakages
  • Horn: make sure the horn is working correctly
  • Examination of suspension and shock absorbers
