The code you have indicates that the compuvalve and the engine pcm are not communicating together anymore. This can be caused by a communication wire from the compuvalve to the pcm, but the most common cause is the compuvalve itself.

What is your next guess, because I just swapped out a known good compuvalve from my other identical truck, and the code still pops up.
Ford Mechanic: EricFromCT, Ford Technician replied 8 months ago

The communication wires from the pcm to the compuvalve will need to be checked for continuity.

Customer reply replied 8 months ago
Let me try that and I'll get back to you.
Ford Mechanic: EricFromCT, Ford Technician replied 8 months ago

Ok. DO you know which wires are the communication ones?

Ask Your Own Ford Question
Customer reply replied 8 months ago
You could give me a hint...before I do that, is it possible that the ECM could be the problem, or do you think the wiring is suspect? There are no other drivability issues, runs perfectly. The monitors all run...
Ford Mechanic: EricFromCT, Ford Technician replied 8 months ago

It is possible that the ecm is the problem. Compuvalve pin 14 tan/orange to pcm pin 16 tan/orange. compuvalve pin 16 white to pcm pin 15 pink/black.

What Customers are Saying:

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.

MollyUSA

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

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
