Facet Oxygen Sensor Lambda Probe

The Facet Oxygen Sensor (Lambda Probe) monitors the oxygen content in your exhaust gases and sends that data to the engine control unit (ECU). The ECU uses it to keep the air-fuel mixture at the right ratio. A working O2 sensor, also called a lambda sensor or air-fuel ratio sensor, helps the engine run efficiently. It also helps keep emissions low.

Key Features:

• Gives the ECU accurate exhaust oxygen readings for precise fuel mixture control
• Supports fuel economy, smooth engine performance and emissions control
• Built for the heat and exposure of exhaust system operation
• Replacement-quality design from Facet, an established supplier of aftermarket automotive parts
• Available in multiple configurations. Select the correct variant for your application.

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle and higher emissions. Replacing it restores correct feedback to the engine management system.
