We bought this truck in Colorado as soon as it was unloaded off the delivery trailer. When we first started it, it had the "low tire pressure" warning. The dealership in Colorado took care of that, and it didn't come on again. After two trips to Arizona, we had the same dealership in Colorado change the oil and rotate the tires. Shortly after we had the low tire warning again. The dealership down here told me that the Colorado dealership didn't "train" the tires when they rotated them, that the front tires and the back tires have different pressure requirements. This sounds like baloney to me. What say you guys?

Stick with the vehicle in your signature. I have a Toyota with tire pressure sensors. When mine goes off, I have a low tire. Does not matter where the tire is or rotated to. I call BS on the Arizona dealer. I have never heard of training the pressure sensor.

Well one thing i know on my 2016 Lariat Screwcab FX4, The rear tires are 20 psi higher then the fronts. So could be true. Just going from memory now. :)

Not to call you out, but the owners manual states to reset the tpms after tire rotation.

"Note: You need to perform the tire pressure monitoring system reset procedure after each tire rotation on vehicles that require different recommended tire pressures in the front tires as compared to the rear tires.

Overview
To provide the vehicle's load carrying capability, some vehicles require different recommended tire pressures in the front tires as compared to the rear tires.
The tire pressure monitoring system equipped on these vehicles is designed to illuminate the low tire pressure warning light at two different pressures; one for the front tires and one for the rear tires. Since tires need to be rotated to provide consistent performance and maximum tire life, the tire pressure monitoring system needs to know when the tires are rotated to determine which set of tires are on the front and which are on the rear.

With this information, the system can detect and properly warn of low tire pressures.

System reset tips:
• To reduce the chances of interference from another vehicle, perform the system reset procedure at least three feet (one meter) away from another Ford Motor Company vehicle undergoing the system reset procedure at the same time.
• Do not wait more than two minutes between resetting each tire sensor or the system will time-out and the entire procedure will have to be repeated on all four wheels.
• A double horn will sound indicating the need to repeat the procedure. Performing the System Reset Procedure Read the entire procedure before attempting.

1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all four tires and have access to an air pump.

2. Place the ignition in the off position and keep the key in the ignition.

3. Cycle the ignition to the on position with the engine off.

4. Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds. If the reset mode has been entered successfully, the horn will sound once, the system indicator will flash and a message is shown in the information display. If this does not occur, please try again starting at Step 2. If after repeated attempts to enter the reset mode, the horn does not sound, the system indicator does not flash and no message is shown in the information display, seek service from your authorized dealer.

5. Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following clockwise order: Left front (driver's side front tire), Right front (passenger's side front tire), Right rear (passenger's side rear tire), Left rear (driver's side rear tire).

6. Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds. Note: The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.

7. Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.

8. Remove the valve cap from the valve stem on the right rear tire. Decrease the air pressure until the horn sounds.

9. Remove the valve cap from the valve stem on the left rear tire. Decrease the air pressure until the horn sounds. Training is complete after the horn sounds for the last tire trained (driver's side rear tire), the system indicator stops flashing, and a message is shown in the information display.

10. Turn the ignition off. If two short horn beeps are heard, the reset procedure was unsuccessful and you must repeat it. If after repeating the procedure and two short beeps are heard when the ignition is turned to off, seek assistance from your authorized dealer.

11. Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver's seating position) or Tire Label located on the B-Pillar or the edge of the driver's door."

Yep, same procedure for my 2011.
But I just take it to back to the dealer for the oil change, tire rotation, 30 point check package deal

Easy !!

The way I read it, every time you rotate/get new tires.

I think you can go in and reprogram it to whatever pressure you want. So some set it real high, that way the warning doesn't come on. In effect, disables the system.
