Did the same and it worked for me so far. While a "used" sensor might still work their aging mechanism is that they get slow due to continous poisoning of the active element. Their response times to O2 concentration changes lengthen until the DME's feedback loop eventually gets confused. That's when it starts to throw up the CEL and fault codes.
