Dodge Ram 1500
On the 2004 Dodge Ram 1500, there are a couple of things that can set the P0441 code. This can be a problem in the Leak Detection Pump or the EVAP Purge Solenoid. More commonly on these vehicles, the LDP, but both should definitely be tested for proper operation. Carefully inspect the electrical connectors and wire harnesses, looking for any loose, broken or damaged wires. Make sure to carefully inspect the vacuum lines to each for any cracks or holes as a faulty vacuum line can also set this code. The LDP is located at the front of the fuel tank near the Canister. The Purge Solenoid is located under the hood, mounted to the Power Distribution Center.
