Denso Lambda Sensors – DOX-1500

Denso Lambda Sensors Part no. DOX-1500 are crucial components in the automotive industry. These sensors play a vital role in monitoring and controlling the air-fuel ratio of an engine, ensuring optimal combustion and reducing harmful emissions.

Importance of Lambda Sensors

Lambda sensors, also known as oxygen sensors, are responsible for measuring the oxygen content in the exhaust gases of a vehicle. This information is then used by the engine control unit (ECU) to adjust the fuel injection and ignition timing, ensuring the engine operates at its peak efficiency.

How Lambda Sensors Work

The Denso Lambda Sensors Part no. DOX-1500 consist of a ceramic element coated with a mixture of platinum and palladium. This coating acts as a catalyst, allowing the sensor to detect the presence of oxygen in the exhaust gases. When the oxygen content is high, the sensor generates a low voltage signal, indicating a lean air-fuel mixture. Conversely, when the oxygen content is low, the sensor generates a high voltage signal, indicating a rich air-fuel mixture.

Benefits of Denso Lambda Sensors
