Question been stuck for about a month now

I have done reading and searching and now I'm just stuck.

My car is throwing a few codes P0446
(Evap emission system vent control circuit) P1400 (egrc solenoid) P0450 (Evap emission system pressure switch) P0443 (evap emission system purge control valve circuit) P1105 ((Manifold absolute pressure/bar switch solenoid/ circuit) But before these codes had others I forget what they are. I remember I pulled the sensor on the evap canister and the evap canister was Leaking charcoals in my evap system so I got a new canister and new sensor. I unhooked everything in the back by the canister and I unhooked the evap purge cut valve ( black thing with 2 same size hoses and one small hose at the top) and I also unhooked the evap purge volume control valve( both located top of the intake mani) and they both had charcoal in them from the canister. So I blow them out with air compressor and I also blew the lines back by the canister. I figured I got all the stuff outa the lines. I cleared the codes cause I out the new canister and sensor on and now I'm gettin the above codes and can't get them to ago away and I need to pass inspection last month. I been reading and figuring this out for over month and half I read on this website and a lot of people said the gas cap. And said the sensor on the canister gets stuck mine was and I replaced it and it opens when a 12v source is there. Any input would be greats thanks


Oh an one codes says emission system purge control valve circuit so think it would be a sensor!?

One I have a brand new inspection sticker my 3.5 swap is happening the motor has been on the stand done since September

 

Ok so I guess no one has an answer for me! Well I done more searching and more testing and came up with im only getting

P0446
P0450

They come on as soon as I turn the key! I scan it and they are pending and then few key cycles the light comes back on.

I figured all the other stuff out. The Egrc code was cause the sensor next and down under the intake manifold was beat. I had a nice day of 35 degrees so I pulled everything apart. I checked the 3 sensors that all look alike. They all clicked expect the Egrc solinoid so I replaced it. Also wile I was there I put a paper clip in the map/bare sensor and checked the readings and the readings change from when the key is turned on(car off) and then when vacuum is applied.
So now I'm stuck with the p0446, and p0450 code. I replaced the evap canister(it was leaking charcole was leaking out into the line) I replaced the vent sensor that bolts to the canister(I even checked it it clicks on and off when I apply 12v to it) I checked the other to sensors down there as well. One needs 12v to turn it on it clicks on! And the other has 3 wires to it I checked it to see what the readings are and then when vaccum is applied it checked out fine. Now I'm stuck with the codes.

Btw when I turn the key on(with car on or off) the vent control valve on the canister dosent click on or off it just stays open! Idk if it should close or if it should stay open. I do believe I read somewhere that it only closes when the evap detects something is wrong and it closes so the vaccum and be applied to see if there is a leak! So idk what it should do

But I the p0446 code is a circuit code! I need help I can't figure it the F out.

Thanks guys
