With the high cost of a tank of gas these days, you will want to do everything you can to ensure your vehicle is getting the best possible fuel economy. One of the components that is responsible for the rate at which your engine uses fuel is the Chevrolet Trailblazer oxygen sensor. It is the combination of fuel and oxygen inside your cylinders that generates engine power, and the optimal ratio for this oxygen-fuel mixture is 14.7 to 1.

The job of your Trailblazer oxygen sensor is to measure the amount of oxygen contained in the exhaust leaving your cylinders, so that your vehicle knows how much fuel to inject. Your oxygen sensor takes these measurements and sends them to your vehicle’s computer hundreds of times per minute.

Since the Chevrolet Trailblazer oxygen sensor is the only sensor located near the exhaust manifold, it is the only one capable of providing accurate measurements. When the oxygen sensor is not working right, your engine has to rely on estimates from other sensors, and will inject too much fuel rather than too little. Therefore, a faulty Trailblazer oxygen sensor means wasted fuel. In addition, the excess fuel that travels through your exhaust system when your oxygen sensor is not working can damage your catalytic converter and cost you even more money. If you have noticed a drop in fuel economy combined with sluggish engine performance and foul-smelling black exhaust smoke, you may need to replace your Chevrolet Trailblazer oxygen sensor.Visit our online catalogue to find a full line of Trailblazer oxygen sensors that won’t cost you a lot, but will save you some money at the gas pump.
