Last Wednesday I had an emissions code P0441 come up on my Dakota. It means slow or minor evaporative emissions leak detected. I found a hose coming from the Leak Detection Pump at the test port that was split badly at the end. I cut the end off, still had enough slack to reattach the hose to the test port. I had the code cleared at Advance.
Today the code came back. I checked the evap canister and all the hoses, and the hoses at the LDP and purge solenoid (on my truck they are a single unit). I couldn't find any cracks or problems with the hoses, so I figured I would start with the easiest and cheapest thing first and bought a new gas cap at Advance and had them clear the code again. I figured a 10 year old gas cap that gets used at least once a week needs replaced anyway.
If anyone has any more ideas I would appreciate the help. I hope I don't have to pay for a smoke test at the dealership....
