Unusual Pressure Pro failure mode

Middle of a construction area, torrential downpour, one of the sensors decides the normally-85 psi outer driver dual tire is at 119.  Inner dual and tag read fine, but Steve backed it way down until we could pull off at the next (several mile ahead) exit.  Readout jumped to 134 psi when we hit an expansion joint.

Pulled over - tire temps are fine.  Truck gauge reads 90.  Swapped PP sensor with inner dual.  Now reads 168.  Took sensor off.  10 minutes later, still reading 168 despite not being installed.  Steve taps it on the dash - readout drops to 12 psi.  I tap it on the dash, readout says 132 psi.  Tap again, 17 psi.

Delete sensor from programming.  1 minute later, all tire values blank on controller and the beeping commences.  Unplug, rest 10 minutes, plug back in, remaining 11 sensors are all fine for the next 2 hours.  These sensors are barely a year old, were stored at home over the winter (so they've never been subjected to freezing).

If we were shopping for one again we would consider other brands, like TST, instead.

I'm glad to hear Steve didn't ask you to go check it out while traveling!  Glad everything checked out ok!

         For the 06 Phenix , I bought a complete set ,toad and all . Never could get them to stop leaking . Flat tire over and over while setting in coach house . After a few weeks I gave up , took them off and swore I'd never use that name brand again .Well low and behold my present coach came with them straight from the factory . To my surprise to date , no issues . I must not have been holding my mouth right while screwing them on . After all that is really tough to do. ;D  If I buy another set down the road , it will be another name brand .    Brad Metzger

I'm no expert but I think you have a problem. And, its that you treat your equipment too good. Take that PP sensor out and throw it down the street, leave it in a glass of salt water overnight and then dry it in the oven at 140. I bet it will work fine from then on. IMHO

Or put on a new one.

Could you have been in an area where an errant radio signal was being received or maybe something new in the coach was putting out an RF that confused the Pressure Pro? Tell us, what new toys do you have?

I just do not use them at all.  To many issues and flats. I have 300k miles now and has one flat tire that was a valve stem working loose. I would call PP and see what they have to say.

Two months ago, I had one PP sensor that was 1 1/2 years old just go dead, no signal, no nothing. I sent it back to Advantage Pressure Pro, who tested it, found it dead, not a battery issue, and sent me a replacement (not a new one, but a functional sensor), no charge. I would contact Doug McMeen, at Advantage PP, and send your sensor to him. They want know when their sensors aren't working. That was my first bad sensor (of 10) in 7 years of using them (two sets).

For me...No TPMS on those huge high pressure tires.  And since the new tires were installed a couple weeks back, no valve extensions either for the inner duallies.  During the past 10 years, I just manually check the pressures before departure and stay away from trouble if I can at all avoid it.  Now the new Jeep has TPMS installed from the factory.  We'll have to see how this works out for me.  I still plan on taking my own measurements once a week for this Wrangler (Oscar).

We will be doing the same thing once we get to a place where we will be for more than a few days.  I think I'd rather have it fail going to zero then a slow climb in pressure leaving you waiting for a small nuclear explosion to occur while you try and find a place to pull over :-(  Of course I'd rather not have them fail at all !

Hummm .. I *think* you may be right, there are these little round knobs on the end of all my tire stems, are they supposed to look like that :P

Nothing new in the coach that would have caused a sudden interference problem. My favorite part was standing in the coach with the sensor in my hand and it still reading over 100psi ... accuracy +/- 100 PSI

I would hope/think the "internal" version from the auto industry is more robust ... but all it takes is one small grain of sand component from parts unknown ltd to go pop.

Kent hit on it!  It's that new oven!  I bet Michelle was baking some of those awesome cookies while in that construction zone so she could hand them out to the workers as you passed by them! 

Maybe?

My 2011 Xterra has the factory TPMS. In a little over 30,000 miles it did help me out when I had a slow leak that turned out to be a 2" screw in the passenger rear tire but I've also had one false alarm. :( Just can't trust these infernal gadgets!

see ya

My 2005 Mountaineer has them. The 2004 Town Car does not. Twice now the Mercury has alerted me to a problem. The only "false" alerts I've gotten have been when the temperature dropped. Even then, by the time I drove from home to school or school to home the alert had gone away. I noticed tonight that one tire on the Lincoln seems a bit low, so I'll have to check it in the morning.

I'm getting new tires for the coach this month and I'm going to put the new internal sensors on at that time.
