Bosch Oxygen Sensor Heated Universal Sensor

The Bosch heated universal oxygen sensor (also called an O2 sensor or lambda sensor) measures the oxygen content in your engine's exhaust. It sends that data to the engine control unit so the unit can adjust the air-fuel mixture. A working sensor helps keep combustion efficient, which supports fuel economy, lower emissions and smooth engine performance.

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
• Universal design is meant to be cut and spliced into the vehicle's existing wiring harness, so you can use it where a direct-fit connector is not available
• Sensing element is designed to give accurate, consistent signals for precise fuel control
• Housing is built to hold up against exhaust heat, vibration and road contaminants
• Made by Bosch, a long-time original equipment supplier of engine management and emissions components

Replacing a worn or failing oxygen sensor can help restore fuel economy, reduce harmful emissions and clear related check engine light codes. Choose the child item that matches your application.
