How to replace the Heated Oxygen Sensor (HO2S) for Bank 1 Sensor 2 on Chevrolet Silverado 3500 Classic?

A proper support system must be implemented to service the Heated Oxygen Sensor (HO2S) for Bank 1 Sensor 2. When fitting new sensors detach both fuel composition sensor electrical connector and the connector position assurance (CPA) retainer. Oxygen sensor installation should start by taking out the HO2S electrical connector from the fuel line clip when fuel composition sensors are present. Drivers should remove the HO2S electrical connector from 4.8L, 5.3L and 6.0L engine models. Next, remove the HO2S. When replacing the sensor use GM P/N 12377953 anti-seize compound on its threads because this compound made from liquid graphite and glass beads helps with future removal. Mount the HO2S while tightening it to 42 N.m (31 lb ft). The sensor electrical connector connection belongs to the 6.0L engine but also applies to both 4.8L and 5.3L engines. When a fuel composition sensor is present you must attach the HO2S electrical connector to the fuel line clip before detaching the CPA retainer and reconnecting the fuel composition sensor electrical connector. Finally, lower the vehicle.
