Do you know what your Chevrolet Suburban oxygen sensor does? Many vehicle owners are not even aware they have an oxygen sensor. Your Suburban oxygen sensor is located near your exhaust manifold. This important component is part of a network of sensors that is responsible for measuring the oxygen content in the exhaust that is leaving your cylinders.

Your engine relies on a precise mixture of fuel and oxygen to generate power. The job of your Chevrolet Suburban oxygen sensor is to tell your vehicle’s computer how much oxygen is present in the cylinders, so the computer can determine how much fuel should be injected.

The optimal goal for your oxygen-to-fuel ratio is 14.7 to 1, and that is what your Suburban oxygen sensor attempts to help your engine reach. When the oxygen sensor is not working right, your onboard computer has to rely on other sensors to determine oxygen levels. Since the Chevrolet Suburban oxygen sensor is the only one that is located close to the exhaust manifold, the information from the other sensors is inaccurate. When your engine can’t tell how much oxygen is present, it will overcompensate and inject too much fuel, because not enough fuel can cause serious damage. This means that a faulty Suburban oxygen sensor wastes fuel. It also causes black exhaust, a rotten-egg odor, and poor engine performance. It can be difficult to tell whether your oxygen sensor needs replacing. If your spark plugs are coated with carbon tracking, this could indicate a faulty Suburban oxygen sensor. A more reliable way to tell is through an emissions or diagnostics test, though a diagnostics test cannot always catch a bad oxygen sensor.Get your replacement Suburban oxygen sensor right here for less.
