The oxygen or O2 sensor is located in your exhaust system and measures the air/fuel ratio in your engine. By sensing the amount of oxygen in the exhaust, it helps the engine adjust the amount of fuel that it consumes. To maintain a proper air/fuel mixture in your engine, it is important that the oxygen sensors are working properly.
If your car, truck, or SUV experiences a sudden increase in fuel consumption or a rough idle, the O2 sensor is a potential culprit. Replacing your oxygen sensor can be inexpensive compared to leaving it unchecked, which can cause poor engine performance, low fuel efficiency, poor emissions, and even a damaged catalytic converter.
