As the prices at the gas pumps keep going up, you will want to do everything you can to ensure your vehicle is getting the most out of every gallon. One way to maintain good fuel economy is to make sure your Chevy Monte Carlo oxygen sensor is doing its job. You will find your Monte Carlo oxygen sensor located near your exhaust manifold, where its only task is to measure the oxygen content in the exhaust that is leaving your combustion cylinders, and send this information to your vehicle’s computer hundreds of times per minute.

What does your vehicle do with this data? In order to create power, the fuel you put in at the gas pump mixes with oxygen in your cylinders. Your engine strives for an oxygen-to-fuel ratio of 14.7 to 1, which is what the Chevy Monte Carlo oxygen sensor helps it to meet.

However, when your oxygen sensor is not working, your onboard computer has to guess at the amount of oxygen in the cylinders. In this case your vehicle will err on the side of caution and inject too much fuel, because not enough fuel can damage your engine. This means that a faulty Monte Carlo oxygen sensor is robbing your car of fuel efficiency and costing you money at the pumps. There are typically a few different reasons for oxygen sensor failure, including contamination by oil, antifreeze, fuel additives, or gasket sealant, and simple wear over time.
