Delphi Oxygen Sensor Lambda Sensor

Delphi Oxygen Sensors, also called lambda sensors or O2 sensors, monitor the oxygen content in your exhaust stream and send that data to the engine control unit. The ECU uses the signal to fine-tune the air-fuel mixture. This supports efficient combustion, lower emissions, and steady engine performance.

Key Features:

• Designed as a replacement for original equipment oxygen (lambda) sensors
• Gives the engine management system accurate exhaust gas feedback
• Helps maintain correct air-fuel ratio control for fuel economy and emissions compliance
• Built to withstand the high heat, vibration, and exhaust contaminants found in exhaust systems
• Backed by Delphi's experience as an original equipment supplier to automakers worldwide

A worn or failing oxygen sensor can cause poor fuel economy, rough running, and a check engine light. Replacing it with a quality Delphi sensor helps restore proper engine management and emissions control. Choose the specific part number that matches your application.
