The City of Memphis has the first fully automated and computerized automobile safety and emission testing system in the nation. This advanced equipment offers greater consumer protection measures and ensures a higher quality of safety standards
Many accidents on our highways and streets are caused by unsafe vehicles. The City of Memphis Inspection Program visually checks every vehicle to find problems which can lead to accidents. A good safety inspection program helps prevent mechanically related accidents.
The City's program offers visual safety checks which include brakes and headlights. Other visual inspections include all glass, lights, windshield wipers, broken lens, mirrors, windshield and muffler/exhaust.
SMOKING VEHICLES ARE NOT INSPECTED.
Emissions testing as required by the Federal Environmental Protection Agency (EPA) is conducted as a standard test at the inspection stations. Automobiles have been proven to be a major source of air pollution; so it is important that the City of Memphis test for emissions to protect and maintain our clean air.
Your vehicle is inspected for tailpipe emission levels of CO (carbon monoxide) and HC (hydrocarbons) in idle. High levels of CO and/or HC mean that your vehicle is running inefficiently. This can be caused by infrequent maintenance, improper adjustments, tampering or malfunctions and may be causing you to spend more on gas.
IF YOUR VEHICLE FAILS EMISSIONS TESTING:
If your vehicle fails the carbon monoxide portion of the test, the problem will most likely be in the following areas:
- Air Filter
- Air/Fuel Mixture
- PCV Valve
- Idle Speed
- Carburetor Float, Poser Valves, Needles, Seat & Jet
If your vehicle fails the hydrocarbon portion of the test, the problem will most likely be in the following areas:
- Vacuum Hoses
- Plug Wires
- Carburetor/Fuel Inspection System
- Spark Plugs
- EGR Valve
- Oil Change/Filter
The following items can effect both CO and HC emissions:
- Catalytic Converter
- Oxygen Sensor
- Electronic Control Module/Computer
- Secondary Air System
If you take your vehicle to a mechanic, make sure he has training for emissions repairs. He may be certified by the ASE (Automotive Service Excellence) or he may have taken Low Emissions Training Sessions provided by the EPA in the Memphis area. A properly calibrated exhaust gas analyzer and diagnostic equipment will assist him in repairing your vehicle. See your dealer for further details.EMISSIONS WARRANTY - 207B
If you are the original owner of a vehicle that is five years old or has 50,000 miles, your dealer may be required to diagnose and repair at no cost to the owner. This warranty typically covers all non-maintenance (for example, air filters are not covered) components for two years or 24,000 miles, and covers all emissions components for five years or 50,000 miles. This warranty is void if you tamper with the vehicle. See your dealer for further details.
When your vehicle has been repaired, you need to get the vehicle retested.
