The code you have indicates a circuit fault for the purge valve. More than likely one of the circuits going to the purge valve has a broken, chaffed or corroded wire.

How can I check wire or voltage
Ford Mechanic: EricFromCT, Ford Technician replied 7 months ago

First make sure you have battery voltage on the red/yellow wire using a volt meter. If you do, then the light green/black wire will need to be checked. You will need to access the pcm connector that has this wire and using an ohmmeter, to start with, you will need to check the wires continuity. Or a lot of people just overlay, or run a new wire to bypass the circuit in question.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
