#Ford Explorer Maintenance

The oxygen sensor (O2 sensor) in your 2017 Ford Explorer plays a crucial role in monitoring the air-fuel mixture in your engine and ensuring the optimal operation of the vehicle's emissions system. Over time, the O2 sensor can wear out or malfunction, leading to poor engine performance, decreased fuel efficiency, and increased emissions. Replacing a faulty oxygen sensor is important to maintain your vehicle’s performance and prevent potential damage to the catalytic converter.
