Delphi Oxygen Sensor Sensor Replacement

The Delphi oxygen sensor line offers replacement O2 sensors (also called lambda sensors or air-fuel ratio sensors) for the exhaust system. An oxygen sensor measures the oxygen content in the exhaust stream and sends that data to the engine control module. The module uses it to fine-tune the air-fuel mixture for efficient combustion, good fuel economy and low emissions.

Key Features:

• Designed as a direct replacement for the original sensor, with a focus on accurate signal output
• Built with quality materials intended to withstand high exhaust temperatures, vibration and road contaminants
• Helps restore proper fuel control and efficient engine performance
• Helps resolve a check engine light caused by a failed or slow-responding sensor
• Available in upstream and downstream configurations, so you can choose the right sensor for your application

Delphi is a long-established global supplier of automotive technology and a recognized original equipment manufacturer. A worn oxygen sensor can lead to poor fuel economy, rough running and higher emissions. Replacing it with a quality sensor helps keep the engine management system working as intended.
