Description

The Denso 234-9051 is an OE-identical Air/Fuel Ratio (AFR) sensor. It features a sophisticated sensing element that provides the ECU with a precise AFR response for improved performance, lower emissions, and increased gas mileage. The sensor is constructed with an aluminum-oxide trap layer to protect the ceramic and platinum electrode, a double protection cover for proper unit temperature and quicker response, stainless steel housing for corrosion resistance, and a porous PTFE filter.
