In this video we look at a 2003 Chevy Silverado 6.0L but the testing is similar for all makes/models. Remember to use only OEM sensors on your vehicle for long-term performance and reliability. Also, If your vehicle has multiple O2 sensors, it is a good idea to replace them all at once since they age together and will fail together at about the same time. Enjoy!
