If you get this code you don't need to pay $200+ just for the part. The $200 part listed is for a relocation solenoid kit. After a lot of Googling I found the original Delco part # for my 2006 GMC sierra 4wd WT. Go to your FLAPS and ask for a Delco 214-2149. This is the same solenoid that mounts to the rear of the fuel tank and mine was $15.26. If you want to relocate it to keep road dirt from getting in just use some heater hose.
