greetings, what engine do you have?
Expert:  ironmike replied 7 months ago.
If you have the 8 cylinder 3.9L there is a cylinder head temp sensor that can go bad. It is under the intake manifold on the passenger side head.

I have seen these sensor go bad after the engine running hot and some just fail under normal engine operation.
