I had a look in the Bentley manual and there is a huge amount of hoses valves and connections to do with the expansion tank that sits between the canister and the fuel tank, It does look like though the only air inlet is the filter on the leak detection valve so the diagram you have probably shows everything relevant to the code if that is the case. So you are back to a restriction in the line(maybe from the purge valve to the canister, that's a lot of line!) the canister itself(probably not),the filter(maybe) or maybe the leak detection valve is not spool is not fully going into the run position(against spring).
