In this guide, we will show you how to change an oxygen sensor on most Chevrolet vehicles. The difficult of changing the oxygen sensor on a Chevrolet depends on the location of the sensor that you are trying to change.
All Chevrolet cars have at least two sensors with some 6 and 8 cylinder engines having up to four. After you read the fault codes you will get a code that points to a bad oxygen sensor such as Bank 1 Sensor 1. This will allow you to identify which one of the oxygen sensors need to be replaced.
Park your Chevrolet, set the parking brakes and open the hood.

Step 5: Remove O2 Sensor
