ETC (Electronic Throttle Control) Cut-out
Had the ETC cut out on me this morning (wrench light on dash on). Went into "limp" mode.
Shut her off, waited about 5 min., re-started (few more cranks to start than usual), light is now off and ran fine the next 10 miles to work.
8 deg. F here in NH this morning. Let her warm up fully. Happened about 10 miles on the way to work.
From a possible senario that i found on the net is one (or more) of the APP sensors on the 3-track potentiometer gave a bad signal.
Has anybody had any similar problems with the ETC? and if so what were your findings and resolutions if any.
She will be going in for service soon after the next round of snow storms.

Thanks

If "ETC" = "Throttle Position Sensor," then I had the same issue last year.

Thanks Dave and Andrew.
Yeah the engine just sat at idle with no response from the throttle. Curious if itl do it again.
Andrew, what was your situation? Did the truck revert back to being ok or did the TPS just quit altogether and you wern't able to drive her?
I have an appointment on thurs morning. It should be covered i have the 100k x-tra guard warranty but ill check when i get home tonight in my warranty coverage list.
Thanks again guys.

I ran some Marvel Mystery Oil in my gas to clean up the fuel system. One night, I was going to get some dinner and started my truck. Pulled out into the road and it just bogged down to a crawl then died. Thank goodness it was a week night and no one was driving down that road. I was there for 10 minutes trying to start the engine. The "wrench" light was "ON" in the dash. It finally started but would barely run. I "limped" back to my house and started my research. I had a scanner so I found two codes and everything said it was the Throttle Position Sensor. I contacted Ed and he shipped the part to me. It took about an hour to replace the sensor and it immediately started up. I haven't had any problems since then.

*update*
Got my truck back yesterday from the dealer.
Before bringing in i pulled codes P2104 and P2111
P2111
The definition of this code is that the throttle angle is greater than expected. This means that the computer commanded less throttle than there was. This can be caused by a sticking throttle plate or a bad tp sensor/throttle body assembly. I would first clean the throttle body and throttle plate with some carb cleaner, clear the code or disconnect the battery for 5 minutes and see if the code comes back. if not it is fixed. if it comes back then you will probably need to replace the throttle body assembly.
P2104
throttle position sensor
Ford replaced the Throttle Body and Motor assy. p/n- 8L3Z-9E926-A
Costs about $500 with labor. Good thing my warranty covered that one.
Also replaced the Carrier Bearing p/n E4TZ-4800-A
Was tired of listening to that.
TSB on replacing it.

With works package (oil change, tire rotate etc..) the Total was $142 ($100 warr. deductable)

Electronic Throttle Control
Whenever I was towing my 5th wheel up grade and pushing the engine, the wrench light came on and power died. Pulled off the road, shut off the engine, restarted the engine and the problem was gone until I pushed it again. Ford dealer said the turbo unison ring was worn. Had it replaced (about $800 job). Tested it today pulling 13,000 lb 5th wheel trailer up steep grade on interstate with pedal on the floor. The problem seems to be solved.
