          What does the Bosch 16073 Oxygen Sensor do?

          The oxygen sensor plays a crucial role in your vehicle's engine management system. It measures the level of oxygen in the exhaust gases, allowing the engine control unit to adjust the air-fuel mixture for optimal combustion. This ensures better fuel efficiency and reduced emissions.

          How do I know if my Oxygen Sensor needs replacement?

          Common symptoms indicating a failing oxygen sensor include poor fuel economy, increased emissions, engine misfires, and the illumination of the check engine light. If you experience any of these issues, consider inspecting and potentially replacing the oxygen sensor.
