Bosch Oxygen Sensor Wideband Heated

The Bosch wideband heated oxygen sensor (also called a wideband O2 sensor or air/fuel ratio sensor) measures the oxygen content in the exhaust stream over a broad range of air/fuel mixtures. It sends precise data to the engine control unit (ECU). The ECU uses this data to keep fuel delivery accurate, which supports efficient combustion and emissions control.

Key Features:

• Wideband design reads air/fuel ratios across a much wider range than a conventional narrowband sensor
• Integrated heating element brings the sensor to operating temperature quickly, so closed-loop fuel control starts sooner after a cold start
• Helps maintain proper fuel economy, drivability and emissions performance
• Built to Bosch quality standards, with a design and construction that resist heat, vibration and exhaust contaminants
• Bosch is a leading original equipment supplier of oxygen sensors, and it developed the lambda sensor
• Pre-installed connector and wiring on many applications simplify installation

A worn or failing oxygen sensor can cause a check engine light, rough running, poor fuel economy and higher emissions. Replacing it with a quality Bosch sensor helps restore accurate air/fuel monitoring and engine performance. Select the child item that matches your application.
