Honda OE Denso Air & Fuel Ratio sensor is designed to detect the amount of the exhaust gas air and fuel ratio. It is constructed from durable material that is corrosion and abrasion resistant. This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precisely controls the amount of oxygen concentration that flows into the diffusion layer to limit current flow. This sensor can easily be installed and ensures longevity.

Denso 02 primary upstream sensor is a wideband air/fuel sensor type that is required for 02-04 Acura RSX Type-S & Base (DC5), 02-05 Civic Si (EP3), and 02-04 Honda CR-V vehicles.
