Check your spare tire. When my truck was less than a year old my light came on and my tires were fine. The spare was low and that was setting it off. I put air in the spare and light went off after about 20 miles. That was over five years ago and and no problems since.
Ford doesn't put TPMS sensors in the spare tires.
In fact you can not change tire positions (rotate the tires) without "retraining" the TPMS system to the new tire locations. Putting the spare in place of one of the tires will result in the TPMS light staying on until the rim with the TPMS sensor is put back on.
There is one in my spare. I also have no retraining as all my tires say 75lbs on the sticker. My spare is the same 75lbs.
