So I just acquired a 2003 1500 crew cab with a mystery motor swap. I’m getting a EAP code P0443 and no power to the harness on either wire also as I was repairing a wire that was broken near the PCM last night, I managed to lose what I guess is a sensor. I attach pictures below if somebody can tell me what this is so I can order it. I’d greatly appreciate it. The harness had a single green wire with an orange stripe . The part that the harness plugs into was bolted to the ground on the fire wall
above the pcm . I’m leaning towards having to replace the pcm and fcm
seeing as certain fuses have no power at the fuse box yet the wiring looks solid and the pcm
thag comtrols the Evap solenoid isn’t sending out a signal hence p0443 circuit A error further more the truck will just randomly shut
fkwn forcing me to cycle the key where it then fires right up . Im replaced the ignition switch / cam sensor , new spark plugs . Relays and Amy fuses that weren’t spares and none of have blown . I need this truck for my daily
driver so any help
is gr

eatly appreciated

 

I'm pretty sure that goes to the light on your hood.

 

there was some type of sensor / connector attached that someone dropped into the engine compartment and apparently it fell into the lost left sock dimension because 3 people couldn’t locate where it fell 🙄🤬

 

Looks like a 4.7? My 4.7 has an intake temp sensor the pokes into the intake tube between the throttle body and air filter, or maybe a MAF sensor. I havent looked into it to hard
