1996 Pontiac Trans Sport

I have a 1996 Trans Sport with the 3400 engine. Over 100,000 miles on it.
The check engine light can on. I pulled the codes and got PO441 EVAP incorrect purge flow and P1655 EVAP purge solenoid circuit fault.
Does this mean I should change the purge solenoid and canister or is there something else I should look for.

I would ohm the purge solenoid and replace it if it reads open or shorted.If this is not a hard failure(failing right now)I would just replace the purge solenoid and or check the wires between the purge solenoid and the pcm.If the solenoid was shorted the ignition fuse for the pink wire should have blown so I doubt it's shorted but could still be open.With the key on you should have b+ at the pink wire of the solenoid so check that also.Let me know what you find.
