Hella Lambda Oxygen Sensor

The Hella Lambda Oxygen Sensor (also called an O2 sensor or lambda sensor) measures the oxygen content in your engine's exhaust gas. It sends that data to the engine control unit (ECU). The ECU uses the signal to adjust the air-fuel mixture. This helps the engine run efficiently, keeps emissions low, and supports good fuel economy and drivability.

Key Features:

• Accurate exhaust gas oxygen measurement for precise air-fuel ratio control
• Supports emissions control and catalytic converter protection
• Helps maintain fuel efficiency and smooth engine performance
• Built to OE-level quality standards, with a design matched to the original application
• Available in upstream and downstream sensor configurations across the product line

Hella is a long-time original equipment supplier to major vehicle manufacturers. It brings that engineering experience to its aftermarket sensors. Replacing a worn or faulty oxygen sensor can help restore proper engine management, reduce harmful emissions, and prevent related problems such as rough running or a check engine light.
