Research on Oxygen Sensor for Chevrolet Cobalt

The automobile has come a very long way since Karl Benz built the first practical gasoline powered horseless carriage back in the 1880s. The 21st Century motor car has a lot of cutting edge technology that helps them run more efficiently while reducing noxious waste, like carbon monoxide. That particular toxic gas once threatened to kill us all - some may remember the amount of smog that would gather over major cities like Los Angeles, back in the 1960s and 70s. These days, exhaust systems have many components that are finely tuned in order to prevent the worst pollutants from escaping from the engine. One of these is the 2005 Chevy Cobalt oxygen sensor, also known as the O2 sensor. As is the case with most vehicles today, the Chevy Cobalt has two of these. There is a 2006 Chevy Cobalt oxygen sensor bank 1 and one for bank 2. While this is not an expensive part to have to replace (they run approximately $20), it's important to have them working properly. Otherwise, 2006 Chevy Cobalt O2 sensor problems can rob your engine of power and performance, and make it likely that the car will not pass an emissions inspection.

The Function of the O2 Sensor

If you are of a certain age (meaning you probably qualified for Social Security several years ago), you may remember a knob on the dashboard of most vehicles, called the "choke." This was attached to a cable that went to the carburetor, and allowed the driver to adjust the fuel mixture by hand, making it "richer" (more gas) or "leaner" (more air). When starting a cold engine, it was standard practice to have the choke pulled out all the way in order to provide a rich fuel mixture to the engine. As the engine warmed up, the driver would gradually push the choke all the way in. Drivers would also adjust the choke lever (as it was often called) when more power was needed, making the mixture richer for climbing hills or acceleration and leaner when cruising over level ground. Today, thanks to the 2010 Chevy Cobalt O2 sensor, drivers don't have to do that anymore. The O2 sensor does it all for you. However, when they start going out, your car is going to start using a lot more gas - and response is likely to be sluggish.

What Happens When an O2 Sensor Starts to Fail

Poor fuel economy is one of the first symptoms of a bad O2 sensor. These devices can be checked with a piece of equipment such as a high-impedance voltmeter, which you can do yourself if you have the knowledge. Otherwise, most professional garages can do this for you.

Replacing the Old One

You'll need to know the 2009 Chevy Cobalt O2 sensor location of the one you'll be replacing, and keep in mind that there are more than one. Chances are, when your O2 sensor started to fail, the "check engine" light came on. If you have the right software and interface, your can plug in your laptop and see the code, which will tell you which O2 sensor is going out, such as the 2005 Chevy Cobalt downstream O2 sensor, etc.
