How to properly service and repair the Oxygen Sensor on Chevrolet Colorado?

To repair the heated Oxygen Sensor 1 you need to first clear any codes using a scan tool and if available do the ho2s heater resistance learn reset to reinforce possible ho2s failure. Remove the cpa retainer and disconnect the engine wiring harness electrical connector from the heated Oxygen Sensor (HO2S) electrical connector. Next, disconnect the ho2s sensor electric connector on the camshaft cover. Utilizing heated Oxygen Sensor wrench (J 39194-B) depulsing ho2s catalyst from the Exhaust Manifold. While installing the new ho2s, it is necessary to apply the anti-seize compound (P/N 5613695) to the threads to make easier the subsequent thread removal from the holes. Thread the ho2s through the Exhaust Manifold manually and then use the heated Oxygen Sensor wrench (J 39194-B) to tighten to 42 nfs (31 lb ft). Finely reconnect the ho2s sensor electrical connection to the camshaft cover, reconnect the engine wiring harness electrical connector to the ho2s connecter, and replace the cpa retainer.

Afterwards separate the wiring harness clip and HO2S from its clip. After taking the HO2S clip out of the engine wiring harness clip position it is possible to remove the HO2S. When installing the previous sensor users should apply special anti-seize compound GM P/N 12377953 or an equivalent product that contains liquid graphite and glass beads to improve its thread functionality. Secure the HO2S by tightening it to 42 Nm (31 lb ft). Lower the vehicle simultaneously while installing the HO2S clip to the engine wiring harness clip and connecting the engine wiring harness electrical connector to the HO2S electrical connector and attaching the CPA retainer.
