My father is a mechanic and he has a diagnostic computer and it says front left bank 02 sensor, which is the sensor on the header, there are sensors on the header and the cats, I have high flow cats, we changed the sensor and light still comes on. I know there is a CEL fix for the Test pipe and HFC, but how do you fix the sensor on the Header?
