Delphi Heated Oxygen Sensor Sensor

The Delphi Heated Oxygen Sensor (also called an O2 sensor or lambda sensor) measures the oxygen content in your engine's exhaust. It sends a real-time signal to the engine control module, which uses it to fine-tune the air-fuel ratio. Accurate readings support efficient combustion, good fuel economy, and low emissions.

Key Features:

• Built-in heating element brings the sensor to operating temperature quickly, so the engine can enter closed-loop control sooner after a cold start
• Helps the engine management system keep the air-fuel mixture correct for better fuel economy and lower emissions
• Designed to meet OE-level fit, form, and function for reliable performance
• Available in upstream and downstream positions and in multiple connector and wire-length configurations across the product line
• Durable construction for the heat, vibration, and exhaust contaminants found in exhaust systems

Delphi is a well-known original equipment supplier of engine management, fuel system, and emissions components. A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle, or a failed emissions test. Replacing it helps restore proper engine performance and emissions control.
