Tire Pressure Monitoring System Fault

[jeff kushner]

Yes, no doubt it WAS going to be in there since they're shared codes/systems good for you Bob for finding it! I glanced at it Bob and I don't see a "display" key. Could that part be somewhere else and where do you think the reassignment code is going?

There was another tab in the spreadsheet (the first tab, IIRC) where "TPMS" shows up. And if I recall even more, there's a link that shows what the display looks like. Granted, this is all for the F-150 which has a different dash layout (center display vs the Expys Left/Right MFDs).

I am a rank amateur with the Forscan tool. It appears the spreadsheets were reversed-engineered for the most part. It'd be nice to get the software spec from Ford. Good luck with that.

I ordered four Airtex Wells OEM style sensors and my mechanic said he will put them in and balance tires for $75. I'll have that done no problem $75 plus the $60 in sensors. I'm okay with replacing them for that money.

We need to get Lokiwolf to see this thread...he seems to be pretty darned sharp with the tech involved in altering some of the definables and he might be able to provide you with that code!

I'll ask Ray(Loki) to look!

Guys, I tried to get this working on the 15 before it was totaled, no luck. I will take a look on our 17. The 15-17 Expys basically have 14 F-150's as far as modules and components. Curious if the 14's had the ability to show actual pressure. I will take another whack!

Thank you Loki for taking the time to comment on this. I thought I remembered you mentioning once before that this might be one of those differences that because of the different dash layout, we may not be able to see them.

I just bought oem blues from ebay for $25 each. For my 06 expedition.

Any issues programming them to your vehicles frequency? How much would you say it costs at the dealer or shop?

My car phone cigarette charger was causing the fault. I replaced it with a better quality product and it doesn't come on anymore. No kidding. Just remove the charger from the lighter and see if the fault indicator returns. May be a cheap and easy fix!

I'll second the USB Charger issue. But I'll add that I do not have cheap ones and the failure still occurs. It tends to happen after driving for 30 to 60 minutes or longer. I guess it has something to do with how the sensors are polled. When it does happen I can just unplug my USB charger and the issue clears in a few minutes. Most of the time now I just ignore the message since I know it is BS.

Any update on this? I have a 2017 Expedition (with Towing Package) and would like to display the tire pressure for all four Tires. I did see a youtube video for a Ford Focus where they were able to get the display using Forscan, but that did not work. I have tried several different combinations to no avail. Does anyone know the magic key in order to get the tire pressure display to show up?

Thank you!
