Help Prevent Your Vehicle From Failing Emissions Testing

Taking your vehicle in for emissions testing can be tough to fit into your busy schedule but failing the test can be an even larger inconvenience. Although your vehicle may not have any noticeable issues that interfere with its drivability, it could still fail smog checks if the emissions components are not working properly.

If you’ve already had your vehicle tested and failed the emissions test, make an appointment at any one of our Sun Devil Auto locations with your vehicle report in hand, we’ll determine the cause of the failure and resolve it quickly and efficiently to help you pass your emissions test.

Some maintenance and repairs are necessary to keep your vehicle in excellent driving condition and to keep your emission components functioning properly. These types of repairs should be seen as an opportunity to improve your vehicle’s overall performance, fuel efficiency, and emissions compliance.

  • Engine Air Filter – A dirty engine air filter prevents your engine from getting maximum airflow. In order for your vehicle to run efficiently, your engine needs a certain mix of fuel and air. Without the proper mix, fuel is wasted.
  • Fuel Injectors – Clean fuel injectors are required for successful ignition. Dirty fuel injectors release a solid stream rather than a mist of fuel, causing much of it to be wasted, thus reducing the fuel efficiency of your vehicle.
  • Catalytic Converter – The catalytic converter helps to reduce the amount of noxious emissions from your vehicle. Although replacing the catalytic converter can help your vehicle to pass emissions testing, finding the actual cause of the failure is ideal to save you money.

A Diagnostic Link Connector Scanner is used to scan and check if the vehicle is ready for vehicle emission testing. Even if the “Check Engine” light is off, it may have too many readiness monitors that are not ready, which can then result in a non-passing emissions test. The vehicle must go thru several drive cycles before the readiness monitors will reset.

These monitors cannot be forced to reset, so it may take several days of normal driving for the vehicle’s computer system to reset these monitors. Sun Devil Auto will recheck these readiness monitors for you, free of charge, before you go to emissions.
