A Chevrolet Avalanche oxygen sensor serves to help keep your combustion system working at its most efficient, and thus plays a key role in the overall health and performance of your engine. Your Chevrolet Avalanche oxygen sensor is located just after your combustion system and from its position after the fuel burn, it measures the amount of oxygen remaining in the resulting exhaust gasses. In this way, your Chevrolet Avalanche oxygen sensor is able to monitor the quality of the fuel burn, because if the oxygen levels are out of the normal range, then that typically means that there is a problem that needs to be addressed.

When a discrepancy is detected, the oxygen sensor sends a signal to the main computer of your vehicle, which then seeks to address the problem by adjusting the air-to-fuel ratio, as that is often the cause of an inappropriate oxygen level in the exhaust. When your air-to-fuel ratio is not at its most efficient, then you can waste fuel by having it pass unburned or incompletely burned into the exhaust system, taking with it unused power potential.

Your oxygen sensor is an important tool in seeing to it that you don't waste your fuel, spending more than necessary at the pumps, which already take far too much of your money in the best of engine performance circumstances. If your oxygen sensor has succumbed to the effects of time and wear, then your main computer is not getting that valuable information, and has probably reverted to the default settings, which tend to be fuel heavy, or rich.
