When it comes to automotive repair, emission problems aren't typically a problem many people think about until something happens or if they are due for an emissions testing. If you live in an area that requires emissions testing, it means your vehicle must pass the requirements for emissions. If your vehicle doesn't pass the emissions testing, you will be required to take your vehicle an automobile or muffler shop for repairs in order for your automobile can be declared safe to drive. Here are some of the most common emissions problems that may cause you to fail emissions testing.

Faulty Oxygen Sensor

If the oxygen sensor is faulty, it won't be able to accurately measure the amount of oxygen in the exhaust gas, which can increase the toxicity of the fumes being expelled from the tailpipe, causing serious emission problems. Along with increasing the toxicity of the exhaust gas, a faulty oxygen sensor can also reduce your fuel efficiency and the power of your engine. In some situations, a faulty oxygen sensor may cause the engine to overheat. If the oxygen sensor is faulty, it is important to take your vehicle to a muffler shop for repairs before emissions testing on your vehicle.

Leak in the Exhaust System

Along with creating emissions problems, there are a number of other problems that be caused from a leak in the exhaust system, including an increase in engine noise, pedal vibrations, reduced fuel efficiency and extremely dirty gas fumes. A leak in the exhaust system can cause the oxygen sensor to have faulty readings, so even a small leak may cause your vehicle to fail emissions testing. The cost to repair a leak in the exhaust system is dependent on the cause of the leak; however, repairs must be done before you can pass emissions testing.

Rich Fuel

Rich fuel mixture means that there is a high amount of carbon monoxide in the exhaust fumes typically caused by the engine burning too much gasoline. Rich fuel mixture can be due to a number of different things, such as a bad oxygen sensor, a leak in the fuel injector, a faulty mass airflow sensor or excessive pressure. The cost to repair any the problem with a mixture of rich fuel will depend on what part needs to be repaired; however, before your vehicle will pass emissions testing, you will need to take your vehicle to a muffler shop to determine the cause of the rich fuel and to repair the problem.

There are a number of other emissions problems that may prevent you from passing emissions testing, including problems with the carburetor, the fuel injection unit or the engine control unit. The best way to ensure your vehicle is in top condition and that it will pass the testing is to have it routinely inspected for potential emissions problems and to take the vehicle into a local muffler shop that is familiar with emissions testing.
