As oxygen sensor technology has evolved, DENSO's engineers have been there every step of the way. From the first thimble-type sensors to heated, quick-response sensors required to meet ever more stringent emissions regulations, DENSO has supplied the OE industry with quality components. DENSO continues to innovate with the latest development in oxygen sensors, known as air/fuel sensors. These components, also known as wide-band oxygen sensors, have a broader response range to provide much finer control of air/fuel mixtures over a greater variety of operating conditions. DENSO helped to develop this important new technology. Consumers can rely on DENSO First Time Fit® air/fuel sensors.
