2007 EXPEDITION ENGINE FUSEBOX #74 KEEPS BLOWING UP

[RXTII]

Hello,
I have a situation that fuse #74 on the engine compartment fuse box just keeps burning or blowing up and is a 20amps. small fuse that I want to know what does the abbreviations stand for so I can check the wiring to diagnose why it just keeps burning the fuse.

PCM (sensors) - HE GO/CMS, MAFS, EVMV, CMCV, Speed Deactivation Switch, VCT

anyone can tell me what the abbreviations mean so I know where to check?
thanks in advance!
