lynx the shut off valve is the vent valve is it?

if it is, i checked that with the bi directional scanner and it opens and closes the backdoor pretty good since i also introuduced air and smoke in that area of the canister and i could visually see the smoke apear and disappear when i commanded the vent valve on and off the scanner. i did the same with the purge solenoid.
cleared the code and still got the CEL, MIL

as off today, is still havent got a chance to check the FTP sensor since its been a very busy week for me at the shop.
