The annoying thing for me is it occurs all the freaking time. I spend roughly 6-8hrs a day in the truck for work so I'm constantly plugged in with my Wilson sleek booster and cell phone since I'm also on the phone often for work. I bought the truck with plans to use it as my office in the field and now I'm beginning to regret it since I need the outlets for work and am being told by Ford that "some" devices when charged create RFI. I think it's crap since all my devices create RFI that interfere.

 

is there a way to eliminate the TPMS??? I will be running 2 sets summer and winter tires I routinely rotate I want to deal with this crap

 

Sure buy an H&S Street tuner and turn the TPMS off .

I tried to duplicate charging three phones and three tablets in the truck last night. I couldn't get it to duplicate the problem. I didn't have time to take a long drive, but I'll keep trying.

 

TPMS is here to stay until they design something better.

Or you can take Savage's advice and can solve the problem in a few minutes with a tuner but tuning comes with risk.

 

I actually don't mind TPMS if it behaves itself.

There are three big shortcomings in the TPMS for this truck, IMO.
1) It doesn't tell you which tire is low.
2) You can't adjust it if you don't want to run, say, 80psi in the rear.
3) The PITA retraining procedure.

I solved items (2) and (3) by having a dealer set the the rear threshold to be the same as the front. The dealer where I bought the truck wouldn't do it despite my escalating the thing all the way to the manager. A Ford truck-only dealer did it but it took some convincing.

Anyway, now it doesn't bother me anymore and since it doesn't tell me which tire is low, I don't retrain it when I rotate the tires.

I have a tuner and have not turned the TPMS off since now it basically stays quiet unless I actually have a flat which I did once and it was a nice thing to have when that happened; the flat tire still had lots of air in it by the time I pulled over.

I haven't had the issue caused by charging things but the only thing I charge is my phone.

 

I would check to see how many of the devices you are charging have the blue tooth enabled. Sounds like something (transmitter) is jamming or too many transmitters for the truck to process. Just a guess.

 

Check your spare. I fought w light for a week before I lowered spare and sure enough it only had 40psi.

 

I was thinking that also, but the manual says that only the road tires have a sensor. If the manual is wrong, I would like to know. I had this same problem with my wife's car ,,,, it does have a sensor on the spare.

 

someone said you can take all 5 sensors and mount them in the spare???? If I runa tuner I loose my factory engine warranty right??

 

It seems to me the blue tooth doesn't affect it. I've tried it with my iPod nano and it still faults out.

 

BINGO -
I had an Iphone 4 with the ATT charger that I've ran in the truck since I bought it in 2011 - no problems.
5 months ago, I upgraded to an Iphone 5 and it had a new charging cord. I had a a dual port USB adaptor that I plugged in and used it to charge the Iphone. I started having a problem with my FOB not working worth a crap, and getting a Tire Pressure Sensor Fault problem.
I changed the batteries on the FOB without any changes, still didn't work unless I was standing next to the truck.
I stumbled across this thread and decided to pull the adaptor - problem solved. The FOB works like it did when I bought the truck, I can remote start if from my office, and my truck at the far side of the facility. The Tire Pressure Sensor Fault is gone too.
I liked the adapter since I could plug two items into it to charge - like my phone and my aircard or iPad, but its not worth it.
I may try a different adapter since the original one with my Iphone 4 worked without any issues.
BTW I've always used the port on the passenger side of the dash.

 

I use a dual adapter too. its in the center console.. I didn't see the wire routing notch in the front right for over a year!..
no issues with remote start or TPMS

 

It is my understanding that the threshold for the TPMS sensors is set at 75% of the recommended 65psi front and 80psi rear pressures. I like to run my rears lower than my fronts when unloaded so I retrained the system and told it that the fronts were in the rear and the rears in the front. I aired down to 80% of recommended and after a few days the light came on so I went to 85% which puts me at 68psi for the front tires and 55psi for the rears and have not had the light come.

Per Michelin and my actual axle weights I can go even lower without safety issues.

 

I think the little book in the glove box states if tires rotated you must reprogram them.

 

I've rotated mine twice since I bought the truck and they pick up the new location automatically. This worked for me but I know it hasn't worked for others and they have had to go through the reprogramming procedure.
