Oxygen Sensor Replacement Video 

Your oxygen sensor helps your engine stay efficient every time you drive. Also called an O2 sensor, this part measures the amount of oxygen in the exhaust and sends that information to the engine computer.

The computer uses those readings to adjust the air-fuel mixture so the engine can run cleanly and efficiently.

O2 sensor problems are common as vehicles age because these sensors work in a hot, demanding environment. Over time, their readings can become slow or inaccurate. When that happens, the computer may no longer make the precise adjustments your engine needs for proper combustion and performance.

At APA Total Car Care in Queen Creek, AZ, we diagnose check engine light concerns, emissions-related issues, and fuel control problems to determine whether the oxygen sensor is at fault. If replacement is needed, our team will help restore the accurate feedback your engine depends on.

If your vehicle has poor fuel economy, a check engine light, or signs of an O2 sensor problem, call APA Total Car Care at 480-282-8300.
