Preparing for Your Test

Preparing for Your Test

Preparing for your emissions test doesn't have to be stressful. Here are a few tips from Georgia's Clean Air Force that will help you get started:

  • The most common reasons for emission test failures include: a malfunction in the components of your vehicle that regulate the fuel/air ratio such as oxygen sensor and EGR valve; a dirty air filter, misfiring spark plugs; leaks in the vacuum system; or a poor-fitting fuel cap.  Many of these components can be checked and repaired during routine maintenance service.  It is important to follow your manufacturer's recommended maintenance schedule. 
  • Have your oil changed regularly.
  • Replace your fuel cap securely after filling up.  On 1996 and newer vehicles, the "Check Engine" light may illuminate as a result of a loose fuel cap.  If the "Check Engine" light is illuminated, try tightening the fuel cap until it clicks, then drive the vehicle until the light turns itself off.   If it does not turn off, bring your vehicle in to Braxton and we'll diagnose why the light is on.
  • Keep the sealing surfaces of your fuel cap clean and in good condition.
  • Keep your tires properly inflated.
  • Check belts and hoses for wear.
  • A transmission problem is directly related to the emission control system and can trigger the "Check Engine" light.  A diagnostic analysis will yield a transmission code that will help identify the transmission components needing repair.  Transmission malfunctions can prevent your vehicle from running efficiently, increasing emissions above federal certification limits. 
  • Before performing any repairs, Braxton Automotive will research any recalls, technical service bulletins and manufacturer warranties regarding your emission control system.
