O2 OXYGEN SENSOR

The Denso 234-9073 is an Air/Fuel Ratio (AFR) sensor designed to provide precise output in proportion to the air/fuel ratio. It supplies the ECU with an exact AFR response, contributing to better performance, lower emissions, and increased gas mileage. This sensor features an aluminum-oxide trap layer to protect the ceramic from contamination and a double protection cover to maintain proper operating temperature for quicker response times. The stainless steel housing offers resistance to corrosion and contamination, while a porous PTFE filter allows atmospheric oxygen entry without letting contaminants seep in.
