I have a 2003 accord ex with codes p2422 and po453, i think my evap is clog, does anyone know how to remove the fuel tank vent line going down to the evap under the car.

 

P0453 = fuel tank pressure sensor
P2422 = EVAP canister vent-shut valve stuck closed

I'd say check out the vent-shut valve. You don't need to remove the fuel vapor line.

I'll move this to General Tech. where it belongs.

 

Is this located on the left side of the canister

 

Well, it was on the 1998 when I had that problem. I just looked at the canister pictures & it doesn't seem to be shown at the canister assembly parts drawing. I also used to have a 2003 but didn't have problems with the EVAP system so ??
