Mounted near your exhaust manifold is a handy little component known as your Chevy S10 oxygen sensor. Part of a network of sensors that keeps track of the oxygen content of the exhaust leaving your cylinders, your S10 oxygen sensor is the only one capable of providing precise oxygen measurements to your vehicle’s onboard computer, since it is the only one located in the direct path of the exhaust. The oxygen sensor calculates the amount of oxygen in your exhaust and sends the data to the computer system hundreds of times each minute, and your computer uses this information to determine the amount of fuel that is injected into your combustion chambers.

Without these precise measurements, your cylinders will receive too much fuel, since not enough fuel is damaging to your engine. A faulty Chevy S10 oxygen sensor causes your vehicle to waste gas, and with the cost of fuel today, that is an expense you will want to avoid.

Unfortunately, detecting a bad S10 oxygen sensor is not an easy task. Some of the symptoms of a faulty oxygen sensor are sluggish engine performance, a drop in fuel efficiency, and black, foul-smelling exhaust smoke, which can all be caused by other engine problems. It is good to replace your Chevy S10 oxygen sensor whenever you have exhaust work done, or at least every 100,000 miles.
