The oxygen sensors on a 2011 Chevrolet Aveo are positioned in the exhaust system, located on either side of the catalytic converter. These sensors are responsible for ensuring the proper air-to-fuel ratio in the engine. If there is an imbalance in this mixture, it can lead to the engine running either too rich or too lean, resulting in inefficient operation. In the short run, this may cause a decrease in fuel efficiency, but in the long run, it can lead to increased strain on the engine and potential damage. Oxygen sensors are relatively inexpensive, priced around $30, so it is important to replace them if they malfunction to avoid more costly repairs later on.
