Some of you may not see this as a problem, but I do.

Last spring when I removed my winter setup, and installed the summer mudders, I could not get the truck to learn the left front tire to begin the TPMS re-set procedure. I tried and tried, and failed. I had a oil change appt that week at the dealer anyways, so I added it to the list for them to correct while it was there. Funny thing was, the light indicating that I had a TPMS system failure never came on in the week of driving it before the appointment. Some freeway speeds were had in that time frame.

Oil got changed, and (apparently) the TPMS got fixed. There is a line on my copy of the work order stating that it was repaired. I now believe that the tech figured no light no trouble, although I was perfectly clear to the service advisor when I dropped it off.

Fast forward to today. We had our first dump of Old Man Winter a few days ago, and last night I rolled out the winter set from the shed and mounted them on the truck again. I decided to test the TPMS indicator light and drive it till the light came on. It's a 8 mile one way trip to work, at about 65 miles an hour for more than half of it. Add a grocery trip tonight and the truck has had 25 miles total on it so far and still no TPMS indicator.

Before you ask, the summer rubber setup is NOT in the box of the truck, it is at home in the shed.

How far, and at what speed does the TPMS indicator system activate? I'm thinking I've done more than enough driving for the truck to realize that there is no longer the original TPMS sensors within range.

I have not started the TPMS sensor re-learn procedure this time around yet. I want to see the damn light come on first.

Did my dealer fail me here again?

 

It takes at about 20 mins at speeds over 25 to get the TPMS fault. 8 miles at a time will not do it. Also once stopped it resets itself, so the 20 mins starts all over. Nothing surprising about not getting the fault with your conditions

 

what he said, I changed wheels one time and it took a week to get a light.

I have to say it still amaizes me that with all Ford ultra cool high tech Sync, Nav, and center guage display system that they have the worst TPMS system in the industry. What good is a system that takes so much driving to tell you something is wrong, the tire is destoied or an accedent would have already happened by the time this thing tells you there is a problem. I would rather it not even have a TPMS system at all if this is what they are going to use. GM's tells you instantly, and also tells you what the pressure is in each tire. Fords idot light means if there is slight pressure drop do to temp change you have to check them all by hand to figure out which one is low. LOL

 

It took my 07 about 4 thousand miles to get the light,while my dads truck (2010 f250) the minute he got a flat it lit up

 

My guess is you make a lot of short trips. There is a big difference between a system fault and a low pressure warning.

 

i drove mine for a couple days and it never came on then i went on a trip up north got about 50 miles and then it came on and i know i went more than 50 miles the previous days it goes off the miles you put on it at startup and resets everytime you shut the truck off

 

Thanks for the info. I too agree that a system that takes that long to recognize that it no longer sees the sensors is kind of a waste of time and money. 50 miles? I doubt alot of us ever put 50 miles on it between startups. I rarely do. My '10 has a mere 26,000 km, ~17,000 miles in 2.5 years. Obviously my long trips are few and far between, especially in the winter.

I think I'll just run the re-learn again and call it done. I'm not about to take a 45 minute drive on the highway just to see if a light comes on. No time. Got a new baby in the house. Watching him giggle is way more fun than highway driving.

 

I am still learning how the whole tpms works, so far all I have figured it that it is a pain in the *** if you switch rims and run different tire pressure then what the factory recomends. But, I know this is out of left field but could you take your spare tire off and apart and just glue all the moniters to the rim and then fill the tire back up with air. Then just go drive around till the light turns off and then put the tire back up in place. That way the moniters alawsy see what they want to see and you can do what ever you want with the rest of the tires as far as pressure goes.

 

Different tires with different sensors and different pressures make no difference as long as you train that particular set to the vehicle. You can have one set that is a p series where the recommended pressure is 35 and another set that is a LR E where the recommended pressure would be 50. As long as you train that particular set to the vehicle there should not be a problem. If there is a problem, then that means you may have a bad sensor. The sensors are set by losing a percentage of the air pressure.

 

The day after was an 800 mile trip... At the time I was driving a decent amount.

TPMS came on earlier, probably due to temp changes since all of them still are full of air.

 

I gave up on my quest to see the idiot light. My journey today took me on about a 30 mile route, and still no light. When I got home I re-learned the sensors. It learned as it should this time.
