Facet Lambda Oxygen Sensor

The Facet Lambda Oxygen Sensor (also called an O2 sensor or lambda probe) measures the oxygen content in your engine's exhaust gases. It sits in the exhaust manifold or exhaust system. It sends a signal to the engine control unit (ECU), which uses it to adjust fueling and keep the air-fuel mixture near the ideal stoichiometric ratio. This lets the catalytic converter work properly and helps reduce harmful emissions.

Key Features:

• Supports accurate air-fuel ratio control for efficient combustion and emissions performance
• Heated sensing element for quick signal readiness after start-up (on heated designs)
• Planar and broadband designs available across the range
• Thread pre-greased on many models to make installation easier
• Made by Facet, a European supplier of exhaust management and engine management components

A worn or failing oxygen sensor can cause poor fuel economy, rough running, a check engine light and higher emissions. Replacing it restores correct feedback to the ECU. Choose the child item that matches your application to get the right connector, cable length and thread.
