Trouble Code P0409. Help diagnose
2001 F150 Lariat 4X4; 5.4l

Getting a check engine light showing error code P0409. Can anyone give me any info on this and how to fix it? Seems to have to do with the EGR Vacuum Solenoid, but I don't want to replace it until I'm fairly certain it will fix the issue.

Thanks,

Jim

Well, I seemed to have accidentally fixed the problem. I happened to run some Seafoam thru the brake booster vacuum hose, then also cleared the code. Hasn't back come on since. Other than the weather turning cold, that's all that has changed.
