Ok I have no clue why but I am getting a knock sensor code and I can not get rid of it I got a new sensor and still throws a code? Anyone have any ideas on how i can fix this issue? Car has new gas(shell) put in cleaner? no clue why its doing it.

 

This normally is a wiring issue. It will almost never throw a code for anything other than wiring. If the wiring checks out then I would say swap out the ecu.
