Got the truck back from the dealer. They scanned everything and no trouble or stored PIDS found. Weird since I thought there was some counter that stored how many miles since the last fault or something.
They reset my tire pressures back to 65psi in front and 80psi in the rear and then retrained the sensors. I had all 4 set at 75psi earlier.
What's not clear to me is why that would fix a "tire pressure sensor fault". If my tires were low or too high, it'd make more sense to say tire pressure 'low' or 'high' instead of 'fault'
I guess I'll keep an eye on this. I asked the service adviser what happens if I have the same problem after my 3/36 expires. It sounded like they'd still fix it at no charge since I complained about it already
BTW, I've been driving without my spare for a long time. No issues. It's sitting under my workbench in my garage. When my wife drives without her spare, her car is expecting the 5th sensor and complains accordingly.
It's 125-150 fewer pounds of mass I have spend fuel on accelerating around town :-) Probably doesn't make much difference in the truck, but for sure my wife says without her spare, she feels a big difference in her car, as if she got a few extra HP.
In the past 25yrs, I've yet to need my spare tire(s)...knocking on lots of wood. The few times I've had nails/screws in my tires, I just drove it like for a short distance until I could get it fixed. If I'm going on a cross-state trip, the spare goes back in.
I keep 60 in front and 50-55 in the rear in my factory 20s with Goodyear Wrangler AT/S'. They seem to wearing OK and I rarely haul anything with any weight. When the snowplow goes on, the front go to 80psi and the rear to 65psi with a bed load of old wheels and tires for ballast. For you folks that run 65 or 85 psi empty, are your tires wearing evenly?
I know a lot of people don't, but you SHOULD keep your tires at max. I was told this by the gentleman who is a tire distributer and changes our tires on our fleet trucks at work. That being said I keep mine at 72 all around and max is 80.
Ok so I spent 6hrs at the dealership today trouble shooting my "Tire Pressure Sensor Fault" on my brand new F-250 Platinum Super Duty I spent way to much on. What we've come to conclude is, the module that receives or controls the receiver for the tire sensors, also controls the receiver for the remote keyless entry. It gets radio frequency interference or RFI from various apple products and motorola gadgets that may be plugged into any outlet in the truck (including the USB's in the dash) getting juice. Ford motor company only indicates that "some" electronic devices that are being charged in the vehicle "may" cause RF interference to the TPMS module. The dealership basically said, "don't charge anything in the vehicle" which leaves me wondering why the heck they even bothered putting outlets in the truck to begin with .
I've noticed that when my "Tire Pressure Sensor Fault" message comes on, my truck is nearly impossible to remote start/lock/unlock/panic unless I'm literally within a 12' radius of the truck. After unplugging my iPad, my key fob miraculously started working properly. I'm hoping to figure out how to shield the "module" in the passenger door frame/toe kick so that I can charge my phone, iPod, iPad, and cellular booster since my truck is my office.
So far, my plan is to line the cover panel with some foil and grounding it out, kind of like shielding an electric guitar pick up. If anyone else has any ideas, I'd really appreciate some serious input .
