Yes, My Mechanic found a cracked hose from underneath the vechile (somewhere) but that cleared the small leak code. The for the large leak code he had to replace the canister. Tx

Hi:

It sounds like you had an EVAP system problem. I din't realize that until you mentioned the canister and the "large leak." That is something a little different than just a vacuum leak. Usually, the EVAP system needs fogged to locate the leak and with the EVAP, it is usually more than just a hose.
