I am assuming it is a 4.2 v6. There are 2 solenoids that operate the system and the most common failure is the plastic clips that hold the rods break and the rods fall off. Get them checked and if they are broke, they run about 5.00 each from ford.
If they are not broke, you need to have the solenoids checked to see if they work and hold vacuum.
It is not an easy diag. A code never identifies a bad part, just a failed system. Have it checked correctly and then you can decide your next step.
