Somersworth Auto Repair

Your senses are always essential when you are driving your car. You need to see where you are going; it is important to be able to hear what is happening around you. The feel of your vehicle is important when you're in motion as well. Most wouldn't assume that you need to smell to drive, but it is just as important as your other senses. If you are in your car and smell the scent of what reminds you of rotten eggs, then you need to pay attention.

The presence of anything that doesn't smell good isn't something that anyone enjoys smelling. If you are in your car and you smell a sulfuric or rotten eggs smell then you need to recognize this as an issue and pay attention immediately.

You must know there are three things that can cause your car to have this offensive smell. You can have a broken catalytic converter, your fuel pressure sensor may be failing or you may have a fuel filter that is worn out, and you may have old transmission fluid.

1. Broken Catalytic Converter: Your catalytic converter is a part of your emissions system. Whenever gasoline gets to the catalytic converter, it will transform the amounts of hydrogen sulfide into sulfur dioxide. This will cause the catalytic converter to not process the gases as it should, which will give the smell of rotten eggs. This will cause you to need a new catalytic converter.
    
2. Fuel Pressure Sensor Failing/Worn Out Fuel Filter: When your fuel pressure sensor fails it will clog the catalytic converter with too much oil. When you have a worn-out fuel filter it will allow an influx of sulfur to be deposited into the catalytic converter, burning it out.
    
3. Old Transmission Fluid: When you have old transmission fluid it will leak into other systems causing there to be a rotten egg smell.

In the case that you are smelling rotten eggs when you are in your vehicle you need to have it investigated at once! If you need a strange smell inspected, give our auto repair shop a call today!
