Check and/or change the gap cap, then check the vacuum hose connection from purge valve to intake manifold. Once you've verified good connection...check the vac hose coming off the purge valve, follow it all the way back to the charcoal canister as well as checking the connection to the canister, also check to see if any charcoal bits are leaking from the canister 'system must be blown out if so before any replacement part re to be installed'. Last is the gas tank, There is a rubber cap thats blocks an outlet nipple 'on the top near cab'...this cap like to crack and can even leak gas when driven...check it and fix if necessary.

Just a start...next would be a smoke test on the evap sys.

My 97 ram 1500 reads error code 441 evaporative canister will this cause it to fail the smog test?

It depends on where you live. If you live in a state that requires smog tests, yes, it will cause the vehicle to fail. The test includes verification of the status of the emissions diagnostic codes. In other words, if your car throws a code it won't pass.
