Mounted under your hood near your exhaust manifold is a small component that performs a big job for your engine. The Chevrolet Tahoe oxygen sensor has the responsibility of providing your vehicle’s onboard computer with information about the amount of oxygen contained in the exhaust leaving your cylinders. This is important data for your vehicle to have, since it uses the information to determine how much fuel should be injected into your cylinders.

When your Tahoe oxygen sensor is not working right, your vehicle relies on estimates from other sensors to determine oxygen content, and will end up injecting too much fuel because not enough fuel can damage your engine. Of course, this means a faulty Chevrolet Tahoe oxygen sensor is going to end up wasting gas.

Another consequence of a bad Tahoe oxygen sensor is potential damage to your catalytic converter from the excess fuel that travels through your exhaust system. There are many things that can affect the performance of your oxygen sensor. If the Chevrolet Tahoe oxygen sensor is contaminated with antifreeze, oil, gasket sealant, or fuel additives, its performance may become intermittent or cease altogether. The Tahoe oxygen sensor will also eventually wear out over time. It can be hard to detect a faulty oxygen sensor, but some of the symptoms include poor or sluggish engine performance, a decrease in fuel economy, and black or foul smelling exhaust smoke.
