Your vehicle’s oxygen (O₂) sensors monitor exhaust gases and send real-time data to the engine computer — helping it adjust the air-fuel ratio for optimal performance and low emissions. In this video, Circle & Square Auto Care explains how our technicians test, diagnose, and replace faulty O₂ sensors to keep your engine running cleanly and efficiently.
When an O₂ sensor fails, your engine may burn too much or too little fuel, leading to poor gas mileage, rough idling, sluggish acceleration, or a check engine light. Our ASE-certified technicians use advanced diagnostic equipment to read live data from each sensor, compare upstream and downstream readings, and identify whether the issue lies with the sensor itself or another related component.
If replacement is needed, we install OEM-quality oxygen sensors designed for accurate readings and long-term reliability. When necessary, we also follow the diagnostic procedures used in our exhaust and emissions service to verify that the catalytic converter and fuel system are working in sync.
At Circle & Square Auto Care, our precise testing and expert repairs help improve fuel economy, reduce emissions, and restore your engine’s smooth, balanced performance.
