It's not necessary to replace all four O2 sensors at once unless they are all showing signs of failure. Typically, you should replace only the faulty sensor(s) as indicated by diagnostic trouble codes. However, if your vehicle has high mileage and the sensors are old, proactively replacing them could improve performance and fuel efficiency.
