On Board Tire Pressure Reading

[jorl]

DAMN! I go hear to read about Maverick and feel so sorry for all the people that got EFFEDUP MAVERICKs.Guess I got one built on TUESDAY,nary a problem (30K) and love my truck(and I am a CHEVY guy)

I lose communication with my TPMS Sensors about every other day... 1 or 2 or all go out... then magically appear the next day or so ...

Using a tablet or cell phone, like Apple, their charger with questionable cord? That may be it.

OK

Picked my truck up from the dealer three days ago. Checked the TPM today and it said 40,40,40,39. Will try to check tomorrow with several gages to see if there is any agreement.

If you meant you just bought your truck, that's pretty likely the actual pressure. My Mav and many others were delivered with 40+psi. Apparently they overfill the tires for shipping, and the dealer is supposed to adjust it, but don't.

I lost trust in the TPMS when the Ford tech came to do the taillight recall. I had been monitoring the pressures and they all showed good. As part of the recall apparently they have to recalibrate the sensors (I suppose because the BCM computer is reset?). As soon as I got in the truck after he left, the low tire warning showed up, and I had to put 5-6 psi into each of them.
Has anyone else experienced this?

The mobile tech who did my software dump warned the TPMS system might be affected. He didn’t have his sensor “clicker”. I took truck to closest Ford dealer, they did it at no charge.

But I was watching TPMS before the reset, and seen no adverse effects.

I've had the truck onscreen TPMS read different pressures on two consecutive days, when my manual gauges didn't change more than a pound.

Not sure if the onscreen TPMS reading is very accurate or not. It is very handy though, to give a ballpark pressure reading. If one tire consecutively shows much lower than the others, I check the TP.

My opinion of the TPMS can be summed up as follows: "It's the BIG ticks on the measuring tape! The little ticks can only be accurately read with your own tire pressure gauge." It's good enough to let you know one tire (or more) is significantly out o'wack but definitely not exceptionally accurate.

I've had the truck onscreen TPMS read different pressures on two consecutive days, when my manual gauges didn't change more than a pound.

This is due to rounding to the nearest pound. For instance, one day a tire is at 34.5 PSI and shows as 35 PSI on the screen. The next day is slightly cooler and the actual pressure goes down 0.1 pounds to 34.4, and the screen shows 34 pounds.

That's probably true but it still doesn't explain the 3 to 4 #s difference between the TPMS and several other gauges (I tried at least 3 on the same day, same session... the TPMS was consistently low)

My truck was over pressure. I adjusted it later. Have a compressor in garage. Use it often. Wife says her Escape tires look low…so I put the gauge on it to satisfy her. Told her not to hit holes or objects on the road, makes tires bleed off air. Seriously, they won’t but she the one who gets the flats!!

My TPMS pressure monitoring screen is fairly accurate. After I air down off-roading, I leave the truck running while I use my compressor to air back up. I can just use the TPMS screen to get back to within 1 PSI of desired pressure on my manual gauges.

That's true, but mine is never that far off compared to my gauges.

Thanks for all of the input, some interesting stuff!

I've used 3 different guages, 2 of the 3 read the same as the on board display, I'm gonna toss the off guage and go with that

Happy Thanksgiving, Merry Christmas & Happy New Year to everyone!!
