I would like to know how O2 sensors function at least in a 4 cyl. vehicle. What does sensor 1 do vs sensor 2? Does sensor 1 have more command to fuel injectors vs sensors 2?
More importantly I would like to know if sensor 1 is defective/lazy, reading lean condition when there’s not one, will sensor 2 be forced lean also, can sensor 2 correct things, or does sensor 1 have more control of things and force the car to run lean?
