I have recently rebuilt the engine and have gotten it back in the truck after 13 or 14 months. I have a few codes that appeared. I retrieved them by using the jumper wire method and was able to resolve several of them. I now have two in this order, the first one I am glad to see code 11 the second is code 53 TP voltage exceeds limits. I did replace the TP knowing it more than likely would not fix any thing.
One other question is the map sensors suppose to have manifold vacuum to it? This thing is fixable right?
