Car Emission Test and Inspection

The Federal U.S. Environmental Protection Agency (EPA) has standards on how much vehicles can emit carbon dioxide into the air. The EPA is to protect the environment and public health from air pollution and dangerous hazardous effects. In 1990, the EPA passed a Clean Air Act which gave them permission to oversea states in regards to emissions.

First Test is Smog Check

is to make sure that the vehicles equipment is intact and that no visible smoke is emitted from the exhaust system

Second Test is the Engine Control Module Check

which is the function of monitoring engine performance such as engine, transmission, exhaust system and the fuel system. Essentially, the OBD checks that the car, truck or SUV is running smoothly.

#1 Problem with Oxygen Sensor and Fuel Trim: These problems result in the vehicle consuming more fuel than normal. This can lead to misfiring and repair of the catalytic converter. This can also be caused by leaks in the vacuum or hose.
#2 Loose, Cracked or Incorrect Gas Cap: This means that there is an evaporative emission problem. Essentially, fumes from gas are leaking out from the vehicle.
#3 Catalytic Converter Needs Repair or Replacement: The catalytic converter turns carbon monoxide to less dangerous carbon dioxide. Poor engine maintenance or bad driving habits can cause the catalytic converter to get dirty or in need of repair.
#4 Weak Spark: The ignition coils, dirty or worn out spark plugs and wire insulation can cause a bad spark to occur which results in misfiring or inconsistent firing. This leads to bad combustion, increased fuel consumption and emissions. This will also damage the catalytic converter.
#5 Engine Overheating and Temperature Problems: It is crucial to have your engine maintained by a professional technician. If the engine has a problem with air flow and temperature, it can cause the engine to overheat. This will prevent the engine from running efficiently and increase hazardous emissions such as hydrocarbon and nitrogen oxide.
