P0441 OBD2 Code on Jeep Liberty: Diagnosis and Fixes After Replacing Gas Cap and Purge Sensor

Model: Jeep Liberty Fault Code: P0441 Posted: 2008-02-08 10:38

I'm looking for help with a persistent P0441 fault code on my Jeep Liberty. I've already replaced the gas cap, purge sensor, and several fuel lines—during which technicians performed a smoke test to check for leaks. Despite these efforts, the P0441 code continues to appear. The issue seems to reappear after about three days of driving. Are there any other components or steps I should investigate? What else could be causing this purge system malfunction? Any advice on troubleshooting or part replacement would be greatly appreciated.

Check the LDP (Leak Detection Pump) — it's a common component involved in P0441 issues on Jeep Liberty vehicles.

I found that some diagnostic tools list 'incorrect purge flow' as a possible cause for P0441. Could this still point to a leak? I know P0442 includes leak-related issues, but where is the Leak Detection Pump located on my Jeep Liberty? My husband has tried to inspect and replace it himself—how difficult is that? Is it something a DIYer can handle, or does it require a professional? And are these parts expensive? Thank you for any guidance—I have many questions!

If the issue persists, I recommend having your Jeep Liberty checked by an authorized dealer to ensure accurate diagnosis and proper repair.
