An important part of making sure that your air-to-fuel ratio is as efficient as it can be, which also means that you’ll be making better use of the fuel you pay so much for these days, is seeing to it that your Chevrolet Malibu oxygen sensor is in working order. Your oxygen sensor is located just after the combustion system, so that it is able to measure the amount of oxygen in the exhaust produced by the burning of the fuel. If the oxygen level is out of the normal range, then that is a good indication that your fuel burn is not taking place at its most efficient, and that you could be wasting fuel, with an inefficient burn allowing some to pass into the exhaust system unburned, its potential power unused.

If the oxygen sensor detects an off oxygen level, then it signals the main computer of your Chevrolet Malibu, which attempts to resolve the problem by making adjustments to the air-to-fuel ratio. If your Chevrolet Malibu oxygen sensor fails, then your vehicle’s main computer is not receiving the valuable information it needs to make the precision adjustments necessary to help your combustion system work its best.

Typically, what will happen is that your air-to-fuel ratio will return to its default setting, which is a bit on the rich, or fuel heavy, side. If you’ve noticed that your fuel economy has deteriorated and you are experiencing reduced power and performance, you may want to check the function of your oxygen sensor.If it does turn out that you do need to replace it, you’ll find an excellent Chevrolet Malibu oxygen sensor replacement selection in our easy to use online catalog, affordably priced and ready to order, either via our always secure site or our toll-free telephone number.
