anyone know what code this is and where would the fuel tank pressure sensor be. 01 screw 4.6

 

P1451 Evap. Emission Control Sys. Vent Control Valve Circuit Malf.

All Ford Codes

You are on the right track. It's a faulty canister vent solenoid, but you should check the harness for power first. It's located under the hood, a diagram of your engine should pinpoint the exact. I don't know off hand where it is on a 4.6. Dealer item only.

 

thanks much. anyway to test it from the canister itself and is there anything i need to do while testing for power, like have the truck on or off etc...
