ERROR CODES P0401
2001 Dodge Caravan • 198,000 miles
My 01 Caravan (3.3L 6 cyl) had error codes p0442 and 0455. Smoke test showed fuel filler neck to be leaking. I had that replaced and now I have those same codes PLUS now p0401. I have not driven the car more than 15 miles yet. I was wondering if the new filler neck triggered the 0401 code by causing there to be a difference in vacuum (or anything else that may be detected as a change) than the van sensors are accustomed to and hopefully will go away after a few drive cycles or should I now be looking for a problem with the EGR?

re smoke test the system for any other leaks.
Yes, t will clear itself after running the test for monitor and passing 3 times.
Thank you so much for your quick response, it is a great help for me! They sure don't make 'em like they used to, not so easy to figure the cars out these days, especially being on fixed income...$90 for smoke test, $90 to have them use their scanner... I know they need to charge to stay in business, but manufacturer's could at least try to consider the people who can only afford "DIY" and make diagnosing easier(thankfully I can at least do "the key dance" to get the codes). Thankfully, we have people like you to share their experience and knowledge! Also helpful to us women who fear being ripped off by shops, which is why I have begun to research my cars problem. Recently paid $150, for parts alone, for a job in which I found parts actual cost was $50 ("but its a life time guarantee, you won't need to do this again" for a 2001, these parts will outlast the darn van! Sheesh, atleast give me the option to decide if I want a lifetime guarantee on parts for a van that I probably won't be able to keep repaired for more than another year). Sorry for the rant, but now you know why I am seeking advice online here. Granted you can't tell me what I should pay for parts, but I think you can see where I would doubt a shops opinion on what the problem is.
