02 sensor circuit malfunction is one of your lambda sensors, there are two one in the top of the cat in the engine and one after the cat underneath the car, best thing to do is get them out and see if one is melted or damaged.

and as for the injector circuit malfunction, is the car running rough or misfiring if it is, the best thing to do is disconnect the injectors one by one, when doing this the car will stutter, however if you have a faulty injector when you unplug the faulty on the car will be no different as it already isnt working
