Oxygen Sensor

Oxygen Sensors, found within the Engine Electronics section of Engine Parts, are critical components in modern vehicle emissions control systems. These sensors monitor the amount of oxygen in the exhaust gases, providing crucial feedback to the engine control unit (ECU) to optimize the air-fuel mixture for efficient combustion and reduced harmful emissions. Typically located before and after the catalytic converter, oxygen sensors utilize a ceramic sensing element to generate a voltage signal proportional to the oxygen levels. Accurate readings ensure proper engine performance, fuel economy, and compliance with emissions standards. Examples in our catalog include Bosch sensors with part numbers 0258027065, 0258007038, and 0281004107, serving a wide range of passenger cars and commercial vehicles.
