On the TPMS, I was getting an alarm every so often on a short trip towing our 5th wheel. According to Forscan the tires were 82.5, 83, 85.3 and 87.5. I assumed that the 87.5 was tripping the alarm. In the manual it only talks about low pressure. Do they also monitor high pressure? My setting is 4150 which says 65 front 80 rear. If I am figuring the hex correctly 41 is front 65 and 50 is 80 rear. Can I use 85=55 and on up? The alarm resets itself until the next time that it trips.

 

Man I had the exact same issue last summer..probably the most frustrating thing I've ever dealt with on this truck. Intermittent, unpredictable, and seems like for no reason at all. Also, bonus points, completely untraceable in the DTC system!

What I came to conclude is that the geniuses at the Sears Auto Center (I know, I know... ) in Mansfield, Ohio (that's right, calling em out by name) put some miracle beads in my tires that were supposed to solve world hunger and balance my wheels at the same time (did no such thing) and caused interference with the signal from the sensors to the TPMS module.

So after going round and round with them about it, I paid again (that's right folks, again) to have them break the tires down, vacuum the beads out, and balance them the right way. Problem is the issue persisted even after the beads were gone which would normally tell me it wasn't the beads fault, but literally nothing else was changed that would point to the cause. My guess is the sensors are irreparably damaged from either the beads or the installation. Google problems with balance beads and TPMS, you will have a long list.

My solution? Used FORScan to diable TPMS altogether. See I made it relevant

To answer your question tho, I'm about 99.5% sure that it doesn't trip when going too high. I'm basing this on the fact that mine were set at 45 and I've had the tires up to 60-65psi and didn't have a light (this was before the Sears fiasco)

 

I used ForScan to set my tpms down to 50 psi both front and rear.
This way i can let some air out of my tires for a better ride when empty...and not have it go off and have to go through the hassle of resetting it.

 

Do you by chance have a phone charger plugged into any of the 12v power ports? If so, that might be your problem. Phone chargers are known problems with TPMS on Fords and other mfgs.

 

Actually Larry I did have the tablet charger plugged in since it's battery won't last very long. I have to try it without the tablet. Jetexpress 67 I'll keep that in mind about the beeds. Ford did replace 1 sensor. The wheel has weights on it so I think there are no beads in it. 06KingRanch what number hex did you use for 50 pounds?

Thanks for some of your help

I forgot about the phone charger suggestion Larry, good call on that.

 

Superdog,

Granted I don't have the factory TPMS and if I did, I would still use a 120v adapter for my phone. Might try that to keep tablet powered and charged.

Using the 120v phone charger might not be energy efficient but it works fine for me. Seems to charge the phone a little faster.

 

The phone charger Tablet adapter is a 120v so I guess I'm OK there. What I did find out was the left rear tire pressure according to my tire gage is right at 80 pounds. I also have a remote tire pressure system and it says about the same 80 pounds. Through Forscan it shows the Ford TPMS on that tire to be 88 pounds. All the rest are close. Are Ford TPMS's in any way adjustable?

 

I havent scoured the interwed yet. Ive had my 2016 apparently for 6mos. The sirus preview is now up. Its not a feature i used even when it was free. Is there a way i can turn it off in the user interface? So i dont have to go thru it when i hit the steering wheel media button?

 

I like using the 110V adapter too. I have a 2 Amp one and it is able to charge my phone while Waze is running. None of the 12V adapters can do that. I have ONE that will at least prevent the batter from draining, the others my phone slowly loses power.

The one I had that was preventing my truck from starting I threw out....

 

I have a 2013 and I am trying to turn the fog lights on as DRL, I have entered the as built data from the spreadsheets that was posted earlier but it gets to 50% and says the as-built info is wrong, can anyone tell me how to get around this or is it not possible?

 

Please post the line 726-11-01 as it appears from your truck, the line 726-11-01 as you are attempting to load into your truck, the exact error message that you receive and the make and model of the odb adapter that you are using as well as specifics of your truck (2013 what? F250 or 350, srw or drw, Lariat, Platinum, etc).

 

Did anyone have any thoughts on this question? I've wondered the same thing.

 

Line 726-11-01 as in the truck is 0001 0000 40 and I am trying to input 0201 0000 42, I first in putted 0201 0000 40 and got a error that the line check was incorrect, and I discovered that it had to be changed to 42, after the line check error was fixed, it goes threw the first stage of programming and then on the second stage of the programing it gets to 50% and the you can here the bcm click once and then I get a error of unable to program (I believe is what it says, I will check tonight to make sure that the exact wording) this is the adaptor that I am using , the truck is a 2013 F350 Lariat, 6.7, srw, crew cab short bed 4x4
