Installation steps:
Step1.Park your Vehicle, set the parking brakes and open the hood
Step2.Disconnect the negative battery terminal. Remove the plastic cover. Loosen the 10mm nut. Remove the negative clamp from the battery.
Step3.Locate the oxygen sensor on your Vehicle. Do not touch the sensor or the heat shield until the engine cools down.
Step4.Press the connector and pull it away to unplug the oxygen sensor. Use a flat head screwdriver to press the locking tab on the connector before you pull it.
Step5.Place the oxygen sensor socket on the sensor and break it loose. If the sensor cannot be loosened spray penetrating oil and let it sit for at least 10 minutes. This will make it easier to remove the old Vehicle oxygen sensor.
Step6.Install the new oxygen sensor. Tighten the new Vehicle oxygen sensor to the recommended torque. If you are not sure what the correct torque call your Chevy dealer.
Step7.Connect the oxygen sensor wire harness by plugging it in.



How does the oxygen sensor in a car work?
The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible.
The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The mechanism in most sensors involves a chemical reaction that generates a voltage. The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly.
The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on all sorts of things, such as the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine, etc.
When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to.
