Default 441 code question

I have replaced gas cap and it did not fix this problem. What is the next logical thing to replace?
Should I replace the purge soliniod next? Or is there something more common to replace. I have gone though everything from one end to the other feeling for cracked hoses and or loose fittings. Everything appears to be in good shape. My light turns itself on and off every 3 or 4 weeks but it is on about 80 % of the time?

Thanks,
Steve

I have done searches but only come up with this cut and paste:


P0441 Evap Purge Flow Monitor -Insufficient or excessive vapor flow detected during evaporative emission system operation.

A Diagnostic Trouble Code indicates that the Powertrain Control Module has recognized an abnormal condition in the system. DTC's are the results of a system or circuit failure, but do not directly identify the failed component or components.

Possible causes for P0441 include:

Intermittent Condition
Checking Evap Purge Solenoid Functionality
Evap Purge Solenoid Vacuum Supply

You will need a DRB III scan tool and diagnostic manual to troubleshoot the issue.

Has anyone ever gone to a dealer who has this tool and found out what it is? Looking for feedback from a few people saying "Yeah it was my?????" or maybe it is your ______ 9 out of 10 times.

Dealers around hear will charge way too much to figure out what it is and then replace the wrong part and tell you you need the next one down the line. Sad but very true. I will take my chances with a 9 out of 10 from this board.
thanks,
Steve

Your problem could also be the NVLD, which is located inside the fuel tank.

I had chronic P0441 for like a year. I swear that it was due to my leaky windshield washers which would occasionally come loose and spray WWF all over the ECM. It seemed to coincide within 24 hours of that happening.

There seemed to be no rhyme or reason to it.

I'm likely to jinx myself, but ever since I replaced the timing belt (last weekend) it hasn't come back. We never touched anything at all having to do with fuel, solenoids, the canister, purge valves or anything like that. I'm knocking on wood.

chronic P0441 : That is a good way to describe this. I am going on 4 years with this problem. I have someone turn off the light the day before inspection and it passes. I think they up graded the equipment that they test with and they can tell if you do this now, that is why I am try to fix my "Chronic PO441". Otherwise I would just leave it, once I got the wife used to the light turning on and off it really is not a problem.

You don't have to have someone else turn off the light for you. Just disconnect the negative battery cable for about 10 minutes. That will clear the memory of the computer and nobody should be able to tell what codes used to be there.
