I just changed my oil, and when I started it up to leak check the eng light stayed on. I did have that one lectrical connector disconnected to lower the filter, but I reconnected it before starting. The codes wereP0243= waste gate pressure control. Next was P0480= fan clutch last was P0461= fuel level sensor no change over time. The last one is probably from filling the tank to max and the level never changing for many miles/time. The first two are what concern me. I don't know if I induced one of them with that connector I disconnected, I double checked it, but the light stays on.
My question is dose anyone know exactly what that connector is for? And what do you think about the first two codes? Sorry for the long post.

 

I use dthe autozone obd2 scan tool and erased all, the only one to come back is PO243 (turbo charger waste gate solenoid A) everything seems fine as far as driving. Anyone have any insite, or has anyone delt with this? I really don't want to have to visit the dealer.

 

Sounds like you did not get the plug seated or it was put on back wards. I would recheck the plug you pulled.

 

^ X 2 ! Double check that plug!

 

I did check the plug twice. It's not possible to put on backwards. there is a sort of key to it.

 

I fixed it. It ended up being a fuse under the hood that has several other items on the same circuit, one being the viscous fan, which probably made it blow when starting with the AC on and as hot as it's been outside 100deg might have played a factor.Any how it's fixed.
