so i have a 96 toyota avalon and my check engine light came on. I went to autozone and got a code reader and it says P0441, EVAP emission control system purge flow fault. any ideas on what this means? the dealer says it'll cost $90 *just* to look at it. it's kinda an old car, so i don't want to pay too much to keep it running. i was hoping that i wouldn't have any problems for at least 2-3 more years. i did some searching online and it seems to be like an o2 sensor or something, but is there anything else it could be? and what could happen if i keep driving it? longer version. i drove cross country 2000 miles. noticed that that o-ring on my gas cap was in a weird position, then later i went into jiffy lube got an oil change, they hosed down something in side the trunk, i was like wtf?! are they running water over my engine? so it was fine, next day, light came on. so i went to autozone, the person there wouldn't even give me the code reader, said it was my gas cap. so i buy a gas cap, unplug the battery, everything was fine. also noticed that my engine oil cap was loose. so then 2 days later, i drive it like 300 miles in a day, it's all good. then i park it for 1.5 days and the light comes on again. so this time i actually read the code and that's what it said. so then i also find these http://www.epa.gov/compliance/resources/cases/civil/caa/toyota.html http://www.usdoj.gov/opa/pr/2003/March/03_enrd_141.htm http://www.usdoj.gov/opa/pr/1997/June97/256enr.htm i'm not sure if my car is one of the ones affected because i don't understand what the pdf from the first link is saying. but i have a 1996 toyota avalon. so then technically this should be covered under warranty, right? well anyways, if anyone has any help that'd be great. cliffs : read the first paragraph.
