I am getting this code & need help figuring out what part to replace now?
P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction

Thanks in advance for the help

You can look up trouble codes HERE.

I believe the Cannister Vent Solenoid on your '01 is located underneath the truck, passenger side, toward the rear, on one of the cross members. It will have vacuum hoses and a two-wire harness connector attached to it.

 

i had similiar codes replaced evap solenoid and purge valve - code went away.
