If the sensors have never been paired with the truck, you then need to activate the sensors. But as said the sensors in the 2015+ are different then the older trucks. The new TMPS has the air pressures displayed on the dash, so it's a more active system.

Here's the reset procedure. Instead of letting air out, I have the ford activation tool TPMS19

Performing the System Reset Procedure
Read the entire procedure before attempting.
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.
Place the ignition in the off position and keep the key in the ignition.
Cycle the ignition to the on position with the engine off.
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.
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).
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.
Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the right rear tire. Decrease the air pressure until the horn sounds.
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.
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.
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.

I had the same thing happen last year when I bought new winter tires/wheels/sensors for my 2016 F-150. The sensors appeared dead, they would not program. I found out that they go to "sleep" after a certain amount of time. To wake them, you need to drive them above about 50 MPH for a certain distance to "awaken" them. Then, program them immediately after they have been awaken.

I don't remember the exact distance or speed to awaken them, nor do I recall the time it takes to go to sleep. However, I drove the truck for about 30 minutes on local 2-lane roads for about 30 minutes, and they programmed just fine.

Similarly, I got new winter tires/wheels/sensors for my wife's Fusion this fall. After installing the new wheels, I took the car for about a 30 minute drive to awaken them. But only 2 sensors would program. I took the car out for another 30 minute drive, and when I got home, all sensors programmed just fine.

The sensor goes to sleep when you stop the vehicle. That is what extends the battery life.

"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."
