P0441 OBD2 Fault Code on 2012 Jeep Grand Cherokee: Causes and Solutions

The check engine light has activated on my 2012 Jeep Grand Cherokee, and a P0441 diagnostic code was retrieved by Pep Boys. An additional code could not be read during the scan. This is concerning as it's only been one year since the last time the check engine light came on, which previously required a full head gasket replacement — I'm now cautious about potential recurring issues. The P0441 code relates to the Evaporative Emission (EVAP) system and typically indicates a problem with the evaporative emissions control system, such as a faulty purge valve or a leak in the EVAP line. While this issue is not always severe, it can lead to fuel inefficiency or failed emissions tests if unresolved. I plan to visit my dealer next week for further diagnosis. I'm seeking community insights and advice on what to expect — especially since the P0441 code has been linked in past cases to EVAP system malfunctions in this model year. Any experienced owners or mechanics who have encountered this code on a 2012 Jeep Grand Cherokee? What were the root causes and fixes?
