Question

What is the cause and cure for the example of the B1252 OBDII code for the 2013 Ford F150 5.0L?

Answer 1

Depends on what the problem is and what part, if any, is required to fix the problem. The B1252 indicates that there is a problem with the USB port. Could be that the port is damaged, or the cable or device you connect to the USB port is damaged. I recommend disconnecting everything from the USB port, clearing the code, and checking again if the code comes back.
