Hey guys I really need some help. I've had my 04 F150 4D Lariat for about 9 months and I cant even drive it anymore. The day I got the truck the Engine Failsafe Mode kicked on. I had the previous owner take it to Beldon Village Ford in Canton Ohio. 2 days later she called me and said that Ford said it was a fuse in the passenger kick panel for the ABS system that had rattled loose. About 3 months later the light came right back on. Now when it comes on heres what happens...As I am driving the ABS and red BRAKE light will come on. about 10 seconds later the ENGINE light comes on followed by a chime and the truck falls on its face. No power and it feels like the truck is choking itself. I reset the same fuse and I was back on the road. Gradually the time in between the mode kicking back on shrank and now I cannot drive it unless I want to get the 4 mpg that I have been getting recently when Its on.
I took the truck to Sharpnack Ford in Willard Ohio. The SM advised that there is a TSB for the TPS that would fix these same symptoms. I agreed to have it replaced and flashed to my PCM. I spent $300. Not even 2 days later the FAILSAFE MODE comes back on. I take it back to sharpnack ford. He says, oh it must be the throttle body, book says replace and retest. I wasn't willing to replace the throttle body unless there was some sort of level of certainty that the throttle body was the issue. He couldn't give it. I told him to find me more concrete evidence that pointed to the throttle body. He couldn't. 3 weeks later he hands me the keys and says we don't know what the problem is, here take it.
I found a known working throttle body off of a 06. I put my TPS on it and install the throttle body on my truck. Same issues almost immediately. I put his throttle body back on his truck and it drove fine. Called ford, said its probably the PCM.
I just ordered a used PCM and it gets here tomorrow. May not be able to get it installed and programmed till next Monday.
I noticed there is a class action lawsuit against Ford for the Electronic Throttle Bodies, PCM, and TCM on these 04-08 trucks, but Ford is only telling me to save the receipts until after the lawsuit is settled.
I stopped and talked to a Ford Tech at Donley Ford in Shelby Ohio. He says its sounds like RF interference.
Heres my question.... What do I test or how do I test for RF interference. Only code is Forced Throttle Induction
So many people have this issue but never update the site once they get it figured out. Any help would be greatly appreciated.
