Hummer Oxygen Sensor

The oxygen sensor is an important part of your emissions control system. It is the sensor that sends data to the engine management computer. Your Hummer oxygen sensor helps your engine to run efficiently and helps it to produce as few emissions as possible. Every vehicle has a ratio of air and fuel that is considered optimal to the engine’s performance. The oxygen sensor measures how much air is in that ratio and sends that data to the engine’s computer. Too much air is called a lean mixture and too little is called a rich mixture. The engine’s computer receives the data and adjusts the amount of fuel to regain the balanced air/fuel ratio. If your oxygen sensor is not working properly, you engine’s performance will suffer. You can expect problems such as hesitation, poor acceleration, surging, and poor gas mileage from your vehicle if your oxygen sensor has failed.
