How to replace Chevrolet Oxygen O2 Sensor

In this guide, we will show you how to change an oxygen sensor on most Chevrolet vehicles.

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. 

Symptoms

  • Check Engine Light is ON
  • A decrease in fuel economy
  • Engine Hesitation or misfire
  • Rough Idling

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 Chevrolet oxygen sensor.

Install new O2 sensor

Install the new oxygen sensor. Tighten the new Chevrolet oxygen sensor to the recommended torque. If you are not sure what the correct torque call your Chevy dealer.
