Hi all. I'm new here and I hope I am posting this on the correct page. Anyway, I was driving my truck home the other day and the cruise control suddenly kicked off. It would not reset. I got home and checked for computer codes and got p 0123 and p 1597. It is my understanding they are for the TPS and Cruise Control. After I checked the codes I drove the truck again and everything is working fine. I still get the codes though. Any ideas as to what the problem is? Is my TPS going bad?
