1999 ford winstar v-6 3.8 l ! what is a canister vent solenoid, i got code #p1451 and where is it located

need to have it check for trouble codes...most auto parts will do it for free

A code P1451 may mean that one or more of the following has happened: VPWR circuit open Damaged canister vent solenoid Canister vent solenoid circuit open or shorted to ground, power, etc. Damaged Powertrain Control Module (PCM)
Verify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage (PCM control side). With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage. When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal. Output test mode may be used to switch output on/off to verify function. Replace canister vent solenoid

Code P1451 is a EVAP control system canister vent solenoid circuit malfunction. If you're lucky it's just a bad gas cap but chances are the solenoid is bad or the wires leading to it are damaged or broken (more likely). Check the attached diagram for the canister location and have a look. If it's just damaged wires you can soldier a new wire splice in place and shrink tube it for protection. Make sure it's not going to rub against any metal that will damage it again.

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.

P1451 FORD - EVAP (Part of the fuel vapor emission control system) Control System Canister Vent Solenoid Circuit Malfunction.The Purge control vent valve is located on the carbon cannister tray near the gas tank in rear of the truck, it is either damaged or has stopped working.

P1451--Evap Control System Canister Vent Solenoid
Circuit Malfunction

Your best to have it diagnosed with a scan tool

If your into throwing parts at it,change the solenoid

A code P1451 may mean that one or more of the following has happened:

• VPWR circuit open
• Damaged canister vent solenoid
• Canister vent solenoid circuit open or shorted to ground, power, etc.

Technical Description:
EVAP Control System Canister Vent Solenoid Circuit Malfunction
The EVAP system monitors the canister vent (CV) solenoid circuit for an electrical failure.
The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command.
Symptoms: You will likely not notice any drivability problems.
Causes: A code P1451 may mean that one or more of the following has happened:
*VPWR circuit open
*Damaged canister vent solenoid
*Canister vent solenoid circuit open or shorted to ground, power, etc.
*Damaged Powertrain Control Module (PCM)
*Possible SolutionsVerify canister vent solenoid - To verify normal functioning, monitor the EVAP canister vent solenoid signal PID EVAPCV and the signal voltage
(PCM control side).With the valve open, EVAPCV indicates 0% duty cycle and a voltage approximately equal to battery voltage.
When the valve is commanded fully closed, EVAPCV indicates 100% duty cycle, and a minimum voltage drop of 4 volts is normal.
Output test mode may be used to switch output on/off to verify function.
*Replace canister vent solenoid
