My only question is how did you determine it was code 25?
According to the diagnostic chart, it's for the right knock sensor. And as a general rule, this is only an open circuit code. It does NOT determine there is a knock, only that it has no way to monitor it. And also as a general rule, the knock sensor doesn't exhibit any driveability complaints, unless the vehicle is turbo charged, in which case it will prevent the turbo, or blower from working. At most, it might retard the timing a few degrees. But since the book says "NO drive complaints", I have to assume it's not programmed that way.
Have you checked for tech bulletins?
Libraries are full of stuff I don\'t know.
