How to replace the Heated Oxygen Sensor (HO2S) for Bank 2 Sensor 2 on Chevrolet Silverado 3500 Classic?

The first step to replace the heated oxygen sensor (HO2S) for Bank 2 Sensor 2 consists of raising and supporting the vehicle correctly. Separate the connector position assurance (CPA) retainer while taking off the HO2S connector clip from the frame. Vehicle owners must disconnect the HO2S electrical connector of 4.8L and 5.3L engines or of 6.0L engines separately. Remove the HO2S. The installation of new or reused heated oxygen sensors requires anti-seize compound GM P/N 12377953 on threads to help sensor removal with its liquid graphite and glass beads composition. Tighten the HO2S with 31 lb ft (42 N.m). The electrical connection for HO2S should be connected to all engines but first to the 6.0L engine followed by the 4.8L and 5.3L engines. The frame procedure requires reattaching the HO2S connector clip and disconnecting the CPA retainer along with vehicle lowering.
