Special Tips to Pass the Louisiana Emissions Test

Louisiana vehicle owners may want to get their vehicles tested as soon as they receive their first testing notice. Allow extra time to get any needed repairs done before your registration expires. Also, if a vehicle owner plans to be out of town during the date when their registration expires, planning early will give owners time to meet the deadline. Here are some tips to keep in mind to ensure passing a Louisiana vehicle emissions test:

  • Make sure the vehicle does not have its “Check Engine” light on; If it does, it will not pass the test. To fix, check to make sure the gas cap is on tight and is not broken. Keep the sealing surfaces in the cap clean so it can make a good seal.  If it is not, tighten it and drive around to see if the light goes off
  • Follow the vehicle’s recommended maintenance schedule. Many of the mechanical issues that cause vehicles to fail their tests can be addressed during a routine check-up
  • If your vehicle is a make and model year when catalytic converters came standard on the vehicle, make sure your vehicle has one and is not malfunctioning; If it does not have one or it is not working, it will not pass the test
  • Allow your vehicle to run for at least 10 minutes before it takes a test to insure an accurate reading
  • Research your vehicle manufacturer’s recalls, Technical Service Bulletins (TSBs), and warranties before getting any repairs done. The cost of their repair maybe covered by the manufacturer.
  • If your vehicle’s On Board Diagnostic (OBDII) system is showing trouble codes, make sure to get them fixed by a certified emissions mechanic. Do not just try to clear the codes.Test personnel will know and the vehicle will not pass inspection.
  • If your vehicle is misfiring when it is idling, make sure to get this addressed before taking the test
  • If a vehicle’s battery is brand new, drive the vehicle for a couple of days before taking it to get an On Board Diagnostics test so as to allow the OBD system to reset
  • Make sure the vehicle’s oil is not dirty. Get the oil changed on a routine basis
  • Maintain the recommended air pressure in your vehicle’s tires
  • Inspect your vehicle’s hoses and belts for wear. Get them replaced if necessary
  • Get any mechanical issues with your vehicle’s transmission address and fixed. Transmissions problems can affect your vehicle’s emissions and cause your vehicle to fail its test
  • If your motor vehicle’s emissions system has a mechanical issue, check your manufacturer’s warranty. Federal law states emissions systems on vehicles made in the 1995 and newer model years must have their emissions systems warrantied for two years or 24,000 miles 
  • If the OBDII diagnostic system or catalytic converter on your vehicle made in the 1995 model year or newer has a mechanical issue, check your vehicle’s manufacturer’s warranty also. Federal regulation states these vehicles must have a warranty on their OBDII and catalytic converters for eight years or 80,000 miles
