Your Chevy Malibu oxygen sensor is part of a network of sensors that monitors the oxygen content of the exhaust leaving your combustion cylinders. Located near your exhaust manifold, the Malibu oxygen sensor is responsible for taking these measurements hundreds of times per minute and sending them to your vehicle’s onboard computer, which uses them to determine how much fuel should be injected into your cylinders. When your Chevy Malibu oxygen sensor is not working properly, your computer is not going to receive accurate measurements and will instead be forced to guess at the oxygen content.

In most cases, your car will end up injecting too much fuel instead of too little, since not enough fuel can damage your engine. A faulty Malibu oxygen sensor can be caused by contamination through gasket sealant, antifreeze, engine oil, or fuel additives touching the sensor.

Your oxygen sensor may also simply wear out over time. You should change your Chevy Malibu oxygen sensor at least every 100,000 miles, and it is often a good practice to replace your oxygen sensor whenever you have exhaust work done. Some of the symptoms of a faulty Malibu oxygen sensor include sluggish performance, hot engine running, a drop in fuel economy, and foul-smelling exhaust.
