Catalytic Converter installation

Is your check engine light on?

In Automotive Diagnostics by HomeTowne Auto Repair & Tire

A catalytic converter helps reduce pollution by changing a vehicle’s exhaust emission.

Ray from HomeTowne Auto Repair & Tire installed a new one on a Dodge Caravan on Monday.

The vehicle was brought to the shop when the check engine light came on. 

When checking the O2 sensors on the computer, he realized that the catalytic converter wasn’t working properly.

Different types of two-way and three-way converters are available. Years ago, one-way converters were used. 

Ray installed a two-way converter, which contains chemicals that changes the air.

The type of converter a vehicle needs depends on the make and model, and how the engine runs. 

Some converters don’t go bad. 

Others may need replacing if a misfire occurs. A misfire shoots raw fuel in the converter, which can’t switch over raw fuel. 

In addition to the check engine light coming on, the smell of raw fumes is another sign that a vehicle needs a new one. However, the check engine light would be your first indicator.

There are many reasons why the check engine light turns on. If it does, it’s a good idea to bring the vehicle into an auto repair shop soon.
