Upstream O2 Oxygen Sensor 2-Pack for Chevy Silverado 1500 Suburban 1500

This upstream oxygen sensor comes as a 2-pack and is made to replace an upstream O2 sensor on the listed vehicles. It has a stainless steel shell, an aluminum capture layer and a pre-coated thread. The trap layer helps protect the platinum electrode.

The sensor measures oxygen content in the exhaust after combustion and converts it into a voltage signal. That signal goes to the engine computer for closed-loop control of the excess air coefficient.
