2015 F-150 XLT 4x4 with the 3.5EB

Last Thursday I was on my way out of town when about two miles from hitting the interstate I get three consecutive dash warnings and the truck goes into limp mode (no power when I pressed the accelerator). I pulled off the road and when I stopped the truck felt like it was idling rough, put it in Park and nothing changed so I shut down the engine. Waited a few minutes and started back up again. The engine cranked an unusually long time, but once it started everything seemed normal again. No dash lights or warnings and a normal, buttery smooth idle. I drove to the nearest truck stop, a couple times on the way there it felt like the transmission was slipping (little bucks and jolts) but no lights or limp mode. A quick visual inspection at the truck stop didn't give me a clue (no fluids where they shouldn't be, nothing obviously wrong with the drive train). I didn't want to have a repeat of the experience while going 85 MPH down the interstate or on the uphill side of a mountain pass so I decided to go home and swap rigs for the trip. The local Ford dealership where I bought the truck new 10 years ago is on the way so I stopped in and asked them to read codes. Halfway there I had the whole thing happen again (took the pictures while pulled over before shutting off the engine). The Ford tech found three codes dealing with the ABS and AdvanceTrack systems but nothing was stored related to the loss of power so he was stumped on that.

I have a service appointment in August (yes, they are that far out) but thought I'd check with the FTE brain trust to see if anyone has experienced the same thing and how bad this might hurt the bank account!

 

My wife's Edge had similar issues....but without the loss of power.
It ended up being the ABS module and pump.

It was intermittent and would sometimes go away for a week or so.

 

The standard initial response for this type of issue seems to be check the state of the battery thoroughly?

 

I haven't done that, but will today. However, the battery is only about a year old.

 

Check the ground cable from the frame to the body. Check both battery cables fro corrosion, If you see any corrosion, replace them.

Also, how many miles, and when were the plugs changed. The plugs in these engines are really only goof for 50k miles.

 

I'll check all the cables, but in my visual inspection when the problem happened I didn't see any corrosion on the battery cables or terminals.

I changed the plugs about 2K miles ago, right at 150,000. Did the boots at the same time, with dielectric grease. Plugs were tightened to the specified torque.

 

How well is it charged. Some make many short trips, it never has a chance to really charge right. Interstate travel weekly is ideal (or battery maintainer)

 

Battery tested perfect. No issues with the cables. Not many short trips for me since I live in the country.

 

2015 Edge V6 and 2016 F-150 5.0 had the same symptoms and messages...both were bad throttle body...no reoccurrences since they were replaced several years ago.

 

The Ford tech mentioned throttle body when I told him the symptoms but then didn't find any codes.

Drove it around doing some chores a couple nights ago without issue. I'll save any long road trips for after the problem is fixed, but for now it seems to be an intermittent problem.

Thanks for all the responses!

 

When I was chasing this out on our Edge, one reoccurring symptom/suggestion/correction was to check the steering wheel alignment.
IIRC, it's called zeroing out the steering wheel or something of that nature.
Some scanners can do that for you.

Never helped.
