the evap system must seal itself to perform leak check diagnosis. if the evap vent solenoid does not close, a large leak dtc will set. check for power to the evap vent solenoid. it should have power with the key on. provide a grd for the vent solenoid. it should click when it opens and closes. if it doesn't, the solenoid is bad.

 

Thanx a milliom tech 2! this is very helpful hint ,,, any one else owns a trailblazer 2006 had this problem gas cap not tight P0455 which triggers check engine and has successfully repaired the issue , it seems like this issue is common with this model... loots of cheers again to all of you
