State Car & Truck Emissions Testing & Inspection

With regular automobile inspections and routine emissions checks, drivers can be familiarized with any problems with their cars. In case your vehicle failed to pass the inspection or the emissions test, you will know it is ready for some prompt attention and potentially some repair or service. Vehicle owners should make plans for the repair as soon as possible because it might endanger the reliability of the automobile and also cause significant penalties and even a disqualified registration. For that reason, it is highly advised to have your vehicle checked by a skilled professional at the very least every 6 months to avoid all these hassles. Some commonly asked questions 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 executed in all vehicles constructed in and after 1996. Simply put, all the cars made in 1996 and after will certainly have an OBD system in them, which offers data records on self-diagnosis of the vehicle often utilized by automobile specialists before doing any type of automobile repair services.


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

A car emissions test can fail for many factors due to malfunctioning vehicle elements such as an injector, oxygen sensing unit, spark plugs or even an EVAP system. The most common cause is malfunctioning injectors. Either the injectors or a malfunctioning oxygen sensor can activate a “rich air-fuel blend” leading to a poor vehicle emissions test.

If your vehicle has a worn-out ignition system, there is a greater possibility that it might be the source of a rise in exhaust discharges. This, consequently, can result in a failed vehicle-emissions test.

Any issue or shortages in the EVAP system or evaporative exhaust control system can cause a problem in the handling of the gas vapor released from the car causing atmospheric pollution.

If your vehicle hasn’t undergone regular maintenance and the “check engine” light is brightened on the dashboard, your automobile might fail the vehicle-emissions test.

  • Headlights: front lights check to make sure of proper operation, no cracked lenses or lights, lights are the correct shade, are the same, and turn signals are operable.

  • Brakes: an in-depth brake evaluation to ensure proper brake action and if there is any brake fluid leaks
