Description

The Denso 234-5706 is an Air/Fuel Ratio (AFR) sensor designed to provide precise output relative to the air/fuel ratio. This sensor enables the ECU to achieve an exact AFR response, leading to improved performance, reduced emissions, and better gas mileage. It features an aluminum-oxide trap layer to protect the ceramic element from contamination and silicone or lead poisoning, while a double protection cover maintains optimal unit temperature for quicker response times. The stainless steel housing offers corrosion resistance and a rugged, watertight construction.
