Hi, if you review the codes at http://www.troublecodes.net/Ford/eec-iv.shtml you can see that the pressure control only applies to the diesel engine and is obtained by self-extraction--not a scanner.
\015\012Therefore, the code 98 in your case is the hard fault. This is the computer saying it cannot execute it's programming due to internal errors in either the computer hardware or software. You would need to contact Ford to determine if a reflash could resolve the issue, but I doubt it would. My recommendation would depend on the symptoms you are experiencing. If there are no issues with the function of the truck and the mileage is still good, you might consider doing nothing. However, if you want or need to get it fixed, I would see if you could find a used computer at a salvage yard. They do not guarantee them to work, but they will refund ot replace one that doesn't. The PCM is located under the passenger's seat or else under the dash or possibly in the engine compartment just in front of the driver and looks like the picture below. A new one costs $184 at autozone.
