This hotrod came in for a CEL complaint, and I found a P0401 fault code in memory. This fault code pertains to low detected EGR flow by the engine computer. I cover troubleshooting this system fairly thoroughly, and the diagnostic procedures performed can be applied to most EGR equipped Ford vehicles of this era. I cover the following in this presentation.
Basic solenoid testing.
Vacuum testing vacuum actuated valves.
Basic pressure sensor testing procedures.
Using scan data for direction.
Manually activating vacuum controlled outputs.
If there is anything you feel I left out or that may help others in the future leave a comment below!
