Fuel To Air Ratio Sensor by DENSO - 234-5047

DENSO's air/fuel ratio sensor appeared to meet the demands of better emission standards in the early 90s. DENSO's air-to-fuel ratio sensors were developed for measuring the air-fuel mixture ratio under a wide range of driving conditions. The air/fuel ratio sensor sends the necessary information to the electronic control unit that makes adjustments based on different driving conditions. This wider range and variable adjustments allow the ECU to control the engine to burn fuel more efficiently and produce fewer emissions. Denso keeps advancing and continues to improve on its standards, as the automotive industry increases its demands.

DENSO oxygen sensors and the technology has developed over years from the first thimble-type sensors to heated, quick-response sensors for meeting the stringent emissions regulations. DENSO has supplied the industry with quality components and continues to innovate with the latest development known as air/fuel sensors. These are wide-band oxygen sensors and they have a broader response range that helps them to provide finer control of air/fuel mixtures over changing operating conditions. DENSO offers this new technology and the consumers can rely on DENSO First Time Fit® air/fuel sensors.
