is there only one 02sensor circuit slow responce bank 1 sensor 1

Question

code P0133 oxygen sensor 02 sensor circuit response bank 1

Answer 1

P0133 - 02 sensor slow response Bank 1 Sensor 1

Yes this is just for one sensor, if it was for a different sensor, you obviously would code it also, and this is the job of the ECM, The whole purpose of the CK ENG LT is to control harmful emission emitted into the atmosphere. and to look for open circuit short circuit, grounds and rationality, what you have is a 02 sensor that is slow, being slow this can be caused if there is a exhaust leak right near that 02 sensor or the 02 resistance is not at specification.
