Tire Pressure Monitoring System Fault

[JExpedition07]

Truck is pretty much where I want it now other than one bug that still bothers me... every time I start it up I get a beep and a message about a TPMS fault on the dash. I looked up the cost of sensors and have no interest replacing them at their price for what they do ($200). Well it's more about tracking it down and actually doing it for something so non essential I guess is the best way I can word it. Is there an easy way to disable and disconnect the tire pressure monitoring system from my display center? It's more of an annoyance than anything at this point. All pressures are good on all four.

Sensor Training (Reset Procedure)

NOTE: The tire pressure monitoring system is not affected by wheel and tire rotation.

NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency (RF) noise.

RF noise is generated by electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.


1.Turn the ignition switch to the OFF position.
2.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.
3.Press and release the brake pedal.
4.Turn the ignition switch to the OFF position.
5.Turn the ignition switch from the OFF position to the RUN position three times, ending in the RUN position. Do not wait more than one minute between each key cycle.

6.The horn will sound once and the TPMS indicator will flash if train mode has been entered successfully. If equipped, the message center displays "TRAIN LF TIRE", place the tire pressure sensor magnet on the valve stem of the LF tire pressure sensor. The horn will sound briefly to indicate that the tirepressure sensor has been recognized by the TPMS module.
7.Within two minutes after the horn sounds, place the magnet on the valve stem of the RF tirepressure sensor.
NOTE: If the VSM (TPMS module integral to VSM) does not recognize any one of the four tire pressure sensors during the tire training procedure, the horn will sound twice and the message center (if equipped) will display "TIRENOT TRAINED REPEAT" and the procedure must be repeated.

8.Repeat Step 7 for the RR and LR tires.
When the tire training procedure is complete, the horn will sound once and the message center (if equipped) will display "TIRE TRAINING MODE COMPLETE".

Thanks for this info J Ski I didn't even put it together these were trainable. I will have to get the magnet and try this out to see if it corrects the problem. Hopefully it does as I just hate putting time into something that doesn't ensure safety or drive the truck.

JExpeidion, if they are the original sensors, you probably have one or more with dead batteries. They are supposed to have a 7-10 year battery life.

Rock auto has sensors ranging in price from $33 each up to $110 each. you can probably find cheaper ones on eBay or Amazon.

TPMS can be deactivated by using Forscan. The info for doing that is on the forum somewhere. I've never used that tool myself, so I can't offer any tips or help with it.

 

[JExpedition07]

Andy you are correct I have seen that info now that I think about it...

I might get a set of Airtex/Wells ones this week if I'm feeling motivated

 

[bobmbx]

There are two types of TPMS sensor. One is the valve stem type, the other is a unit that is strapped to inside of wheel. The strap type can't be trained with the magnet on the stem.

Andy you are correct I have seen that info now that I think about it... now that I know that I will just have to deactivate the tpms as I'm not going to go through the headache of working on such an annoying feature anyway. Dealer wants about a grand to replace them.... HAHAHAHAHAHAAHA!!!! Is that an engineered in cash grab or what?

$90 a unit for oem my cost no thanks... even then i see it as waste. That's Ford pricing I know I can do a lot better on eBay but I'm not feeling it lol.

Don't be fooled by the Orange ones on Amazon and eBay. They suck. put a set in my 05 and they lasted a little over a year. They were cheap but that's all I can say good about them. Bought some Schraders and they were still going strong when I traded it at 2-1/2 years later. It is best to change them when you put new tires on, that way you don't have to pay to unmount and mount and balance tires and wheels.

Personally I like them. I wish they gave a readout of the pressures in the tires.

The Airtex/Wells slash OEM style are the strap on inside ones not valve stem I'd buy OEM style. Found this info out today when i looked at Fords site. If I'm going to do it I'm going to do it how it was originally. Andy the thing that sucks is my tires are brand spanking new... well two months old... I'm not very happy with them but Cooper tires are cheap. I usually like to run Michelin but am giving them a chance.

I had Coopers on the 05. The looked great but the were noisy. I hated them. I was so glad when they wore out and I had to change them.

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

VDO SE10001HP is $28.93 w/ free shipping at Amazon. We've got a set in my wife's car for the last 4 years or so. No issues. When the ones on my Expedition go, I'll be replacing them with these as well. I actually try to avoid OEM replacements whenever possible; most of it is junk in my experience.

The funny thing Andy...is on the Super Duty 250, the TPMS does readout all the tire pressures with a graphic....I would have liked that feature too but for some reason, they didn't put it on our truck!

I'm willing to bet that the programming for tire pressure display is in there somewhere, its just been turned off. I would have a hard time believing that a manufacturer would incur the expense of developing a software version for each model of vehicle they produce. And then do that each year. I'm guessing there is a baseline version and then that is tailored for each model. And the baseline is probably installed on every vehicle with flags set.

Find the flag, change the world.

I wonder if it is in one of the modules that we scan with FORScan and the OBDII connector.

I'm betting that if it is in there we can find it using FORScan. I've downloaded all of my orginal modules and saved them to my computer. I'll have to take a look when I get some time. I downloaded about 5 or 6 additional spreadsheets maybe someone has already identified that section.

 

[bobmbx]

IIRC, the TPMS isn't a real-time system. It reads the pressure at key "ON", and then queries every 5 minutes or so. Thats why the batteries last so long.

I think you are correct Bob. The tire sensors report like once an hour when the vehicle is stationary and every 5 or 10 minutes when the wheels are rotating, but I think the pressure is reported but the computer doesn't display it. It only notifies you when the pressure isn't equal within a set range.

I bought these on Amazon a few months ago when I bought my 2010. They had replaced the rims and removed the OEM bands. These worked fine and got rid of the dash light... Discount tire installed and re balanced the tires for a semi-decent price.
