Hey guys,

I have an '06 Ford Expedition that has been going into fail safe mode for some time now. Just recently I have have started getting the codes p2104 and p2112. If it continues to run, the fail safe mode will shut the vehicle down. If I or the wife turn it off then right back on, it will run fine for a few days or weeks until it, for whatever reason, decides to do it again. I changed the TPS yesterday and it did it again today while driving. It has done this under a variety of situations and can't pinpoint a one. Any help on the this is appreciated before I go to the dealer to get stuck!

Thanks

I just got those codes. About 6 months ago I was getting codes P2106 & P2135. After much research someone suggested disconnecting the 3 big connectors hooked to the computer under the hood on the firewall. After I did that a couple of times I did not get any more codes until now. I just tried the disconnect trick (I work the connector in and out a few times assuming it will make a better connection after that) and cleared the codes. Will wait and see if they come back.
