Replacing 2 oxygen sensors on the 2007 to 2013 model Chevrolet Silverado and GMC Sierra truck. Today I’ll be showing you how to replace:

Bank 1 sensor 1 (driverside upstream O2 sensor) P015B code
Bank 2 sensor 1 (passenger side upstream O2 sensor) P015D code

Get an oxygen sensor tool/socket or set. The shorter crowfoot style ones will be for the driverside but you can fit the longer deep o2 sensor socket on the passenger side one.
