no 02 sensor in new cars Air Fuel Ratio sensors
AKA wide band O2 sensor, lean air fuel sensor, continuous Lambda sensor.
Construction and testing of wide bands is different than old zirconium O2's but it still performs the same function only more accurately and faster.
Bosch developed the breitband lambdasonde around 1994 and it appeared in some cars OEM in 1996 so wide bands have been around for years, nothing new.
