DENSO’s Lambda Sensors – unparalleled innovation since the 1970s

Since the company first started producing Lambda Sensors in the 1970s, DENSO’s continual innovation has helped drive engine efficiency to achieve better MPG and lower emissions, while delivering long-lasting quality to customers.

Opies are proud to stock a huge range of quality Denso Lambda Sensors that cover a massive array of vehicles, so thought you guys may be interested in a quick insight into how Denso have been at the forefront of developing this technology.

HOW IT WORKS: Lambda Sensors monitor the percentage of unburned oxygen present in the car’s exhaust gases. If the oxygen content is too high or low the Sensor will transmit a voltage signal to the ECU. Lambda Sensors are among the most sensitive and critical components within a car’s engine management system, monitoring the air/fuel mixture under idle, while moderating acceleration and cruising engine conditions.

A little bit of history, and how far Denso has come:

DENSO first started producing Lambda Sensors in 1977, and is now one of the world’s leading suppliers, with several hundred million of its sensors measuring the air/fuel mixture in cars the world over. This represents a massive 68% of the European car parc and as the automotive industry continues to tighten its emissions standards this figure is rapidly increasing!

Light duty Lambda Sensors started to appear on vehicles with the development of fuel injection systems. And in the early 90s, DENSO’s Air/Fuel ratio sensor became a world-first innovation as vehicle manufacturers increased demands for better emission standards brought in from EURO 3 onwards. While these earlier systems employed one Lambda Sensor in the exhaust system to maintain closed-loop Air/Fuel mixture control, today’s emissions standards require engines to use up to as many as four sensors, monitoring exhaust gas oxygen content as well as catalytic converter efficiency.

In order to perform these functions properly, the sensors must closely adhere to OE standards. For example, a malfunctioning or incorrectly calibrated Lambda Sensor can negatively impact driveability, resulting in costly repairs. DENSO’s OE quality First Time Fit Lambda Sensors are designed to work with the vehicle’s fuel injection system, Catalytic Converter and Engine Management System to help achieve the lowest possible output of environmentally harmful engine emissions.

EU legislation is now demanding a cut in emissions by 40% by 2030, and DENSO’s Lambda Sensors offer all of the advanced technologies for workshops to provide OEM quality replacements to their customers, as well as enabling them to lower emissions and reduce fuel consumption while gaining optimum engine performance.

To address the demand for OE-quality Lambda Sensors and continue its substantial growth, DENSO continually adds new parts into its Lambda Sensor aftermarket range. At Opies, we are commited to keeping this range up to date, so if you’re after a Lambda sensor for your vehicle, then have a look at our dedicated look up guide HERE.
