      An oxygen sensor (also known as an O2 sensor or Lambda sensor) is a sensor designed to generate a reading based on the content of oxygen in an automotive exhaust system. The sensor itself is made of a ceramic compound with porous-shaped electrodes coated in platinum, surrounded by a protective metal shell casing. O2 sensor casings are threaded, and the entire unit is designed to screw in until it reaches a half-in, half-out position on the exhaust pipe. Modern oxygen sensors are heated to ensure they reach operating temperature quickly.

    Exact Fit For My Envoy 2002
    Couldn't get over 40 miles per hour with out it bogging down, moved 3 bolts at the top and a couple from the back, took a bit to wiggle out backwards but it came out and the new unit slid in. Tightened the bolts and started it up, slight air leak in the gasket, probably will have to re-tighten again as it settles into position. Power is back. Runs perfect now. I would buy and do this again. J.
