DENSO - 234-4260 - Oxygen Sensor

DENSO oxygen sensors emerged with the advent of advanced fuel injection systems and their basic job is to monitor the air-fuel mixture under idle, moderate acceleration, and cruising conditions. Under heavy acceleration, the oxygen sensor goes into an open loop, which basically means that the engine management computer system ignores the oxygen sensor. Oxygen sensors have a limited range and capability in detecting and adjusting the difference from an optimum air/fuel ratio.

As the automotive industry continues to improve on its standards, DENSO is keeping pace with advancements in our engineering to meet the demands of the industry. Furthermore, the vehicle owners are now holding on to their vehicles for longer periods and DENSO continues to make auto parts available for such applications. Oxygen sensors are also known as Lambda sensors and they are among the most sensitive and critical components of your vehicle's engine. Fuel injection systems usually used one oxygen sensor in the exhaust system to maintain a closed-loop control for a balanced air-fuel mixture. However, engines today use four sensors, that not only monitor the oxygen content in the exhaust gas but the efficiency of the catalytic converter as well. The oxygen sensors have to adhere to OEM standards and close tolerances to perform the functions properly. A malfunctioning or incorrectly calibrated oxygen sensor can lead to costly and time-consuming repairs. DENSO First Time Fit® oxygen sensors are engineered to meet these tolerances and provide OEM fit and function.
