Facet 31480396 Heated Oxygen Sensor

The Facet 31480396 is a heated oxygen sensor (also known as a lambda sensor or O2 sensor) designed to monitor oxygen content in exhaust gases. This sensor detects the presence of oxygen in the exhaust manifold and sends critical data to the engine control unit (ECU) to optimize the air-fuel mixture ratio and ensure proper emissions performance.

Key Features:

• Heated oxygen sensor design for faster operation and improved accuracy
• Enables real-time correction of the stoichiometric ratio for optimal engine performance
• Allows catalytic converters to function properly and reduce harmful exhaust emissions
• Manufactured by Facet, a leading European aftermarket parts manufacturer specializing in engine management components
• OEM-quality construction designed for durability and reliability

This oxygen sensor is cross-referenced with OEM part number 31422308. A failed oxygen sensor may cause reduced fuel efficiency, increased emissions, and trigger a check engine light, making timely replacement essential for maintaining optimal engine performance.
