its all on piece but it could be a faulty coolant valve not shutting completely and over heating your DEF, use a heat gun and check the actual temperature of the DEF or on either side of coolant vale to detect a pass by of coolant

The sensor is only available with the Header as far as I know. Our '14 & '15's take an A04-28046-000. We've replaced (22) of them in eight years. (4) in '22, (5) in '23, and (3) so far this year.
