Oxygen sensors are a fairly new component, having been installed as part of the exhaust system in the last thirty years or so. Back when a gallon could be gotten for thirty cents - or even sixty cents (remember complaining about THAT?), fuel economy wasn't the issue it is today. The ideal fuel/air mixture maximizes engine power while minimizing emissions and fuel consumption.

It's a constant balancing act - a leaner mixture means greater mileage and less stuff coming out of the tailpipe, but it sacrifices power. This isn't a big deal when you're driving on the freeway over level ground.

If you're towing a heavy trailer, carrying lot of cargo, or driving in the mountains however, a richer mixture - that is, a greater percentage of fuel - is required in order for the engine to have more power. It's like you - you need more food when you're active. The Chevy Tahoe Oxygen Sensor helps the fuel system determine the ideal fuel mixture by measuring the amount of oxygen in the exhaust. Based on this data, it sends an electronic signal to the fuel-injection system, which then makes adjustments to the mixture for the current driving conditions. A damaged or defective oxygen sensor will cause engine performance to suffer. Power and gas mileage will decrease significantly, while at the same time, harmful emissions will increase. A new Chevy Tahoe Oxygen Sensor is the solution to this problem.
