P1451 obd code on 2002 ford windstar

Here is the definition of the code.
Could be a faulty gas cap, a leak in the evap venting system, a wiring problem, or a faulty vent solenoid. Something caused the system to fail a pressure test.

P1451 FORD Description The Engine Control Module (ECM) detected the canister vent solenoid signal moved outside the calibrated parameters at a specific duty cycle.

Large evap leak for 2001 ford focus

Probably nothing.
The code means the gas tank can not be sealed to prevent vapors from escaping.
Common causes are a missing gas cap when the engine is running, or a faulty hose from the tank to the vapor canister.

P1451---Evap Control System Canister Vent
Solenoid Circuit Malfunction

You can change it yourself & hope you didn't
waste your money

You can have it properly checked out with the
use of a scan tool & an EVAP Smoke Machine,
to see if the solenoid is really bad

What is the code P1451 solution? Runs great, codes P1451, P0171 and P0174 are coming up and the engine light is on. Car needs to get inspected but codes need to be fixed.

P0171 - System too Lean (Bank 1)
P0174 - System too Lean (Bank 2)
P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction
I'm afraid I don't have enough info to tell you how to fix the P1451 but I'm certain it's the cause of the other two codes.
