Hi there,

I have been advised that the sensor after the converter is just a diagnostic sensor and the sensor before the cat is the one that will be giving the fault reading, to prove this, clear codes and unplug front sensor run engine and re check codes, are you still getting the knock sensor code as well or just the O2 fault?
