Denso 234-9005 Oxygen Sensor

Denso Oxygen Sensor is designed to detect the amount of the exhaust gas air and fuel ratio. It is constructed from stainless steel housing and porous Teflon filter that resists corrosion and abrasion. This sensor features zirconia solid electrolyte integrated with alumina heater substrate which precicely 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.
