The sensor is self-heating, which ensures its accuracy in cold engine start-ups. The self-heating feature helps to quickly bring the sensor to its operating temperature, reducing the time it takes for the engine management system to make fuel adjustments. The sensor's design also includes a protective shield to prevent debris and contaminants from entering the sensor and affecting its performance.
