p1457 canister system leakage
00 integra gsr with the above code.
smoke tested and no leaks found.
with bi directional scanner, purge solenoid clicks, vent solenoid clicks, two way valve solenoid clicks. tank pressure sensor tested ok with the multimeter while applying vacuum.
parts that i change so far is the TWO WAY VALVE, vent solenoid, used canister from the junk yard, and a new fuel cap. still the code keeps showing up.
any other common failures for this code? do you have a drivecyle for evap monitor because i usually get the code while driving on the freeway.
im running out of options, im thingking of buying the purgesolenoid next but i hope to get some feedback from you guys coz these parts are really not cheap. thanks in advance
