Good evening, I have a 2010 F150 STX 4WD with 92k showing code p0451. What is your thoughts on this code? I’d even be willing to bring you my truck for you to do a video on it. I live near by, just across the state line.

This is an emission issue, usually a evap pressure sensor under the tank.
Could also be something else emission related, your gonna need a scan tool
and look at some data for proper diagnosis.

EVAP codes are hard to diagnose without scan tools, DVOM and smoke machines. But that code is for a fuel tank pressure sensor. I would start by doing a visual on the connector and wiring. If the sensor is easy to access and relatively inexpensive, change it and cross your fingers.
