I was tootling along in my 2010 F150 Platinum, with 102k miles on it, when all of a sudden my gauges went nuts, my status display cycled through "low fuel," "anti-skid," and "wrench" indicators, then went into limp mode with check engine light. Codes U0100 and U0101 were spit out on my code reader. Disconnecting the battery for 20 minutes clears it all out, and I can drive another 2 to 5 miles before it all goes haywire again.

Anyone encounter this before, or have recommendations for troubleshooting? Thanks in advance.

 

Which motor is this?

 

If it's a 2010, it's the 5.4 3-valve. That was the only engine option for Platinum trim that year

 

5.4L 3-valve.

 

Truck is 2010 lariat 4x4
Keep getting false warning lights
Tire malfunction, swervy line thing, brake light, driver door ajar, passenger door ajar..none of these are actually happening.
The AC WONT work , the radio is blank.
This can happen for 10 minutes and then everything is back to normal. Then it will go off and on repeatedly.
I had some corrosion so I got a new battery..still does it.
I have about 125,000 miles..any advice?

 

You most likely have network wires chaffed somewhere taking down the network. Most common place I have seen is under the seats. The wires are white with blue tracer IIRC and are twisted together.

 

Long bed, thanks for the reply. I don't see any chaffed wires but it has gotten weirder. In the mornings driving to work,everything works fine,everyday but everyday after lunch and the drive home I get the errors and it's the same thing everyday. Ever heard of this? I am going to take it to ford next week. I don't understand how the time of day can make it work 100% and then like clockwork shut down in the afternoon. Any advice is appreciated.
