Check Engine Light Due to Failed EVAP Canister Vent Valve on Nissan Pathfinder

Problem Description and Possible Solution

The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system.  Our technicians tell us a failed vent valve will require replacement.

knock sensor and evap/exhaust purge valve (?) are making my check engine light go on (and preventing me from getting my 6/2011 to 6/2012 NYS inspection). I replaced a similar (possibly the same?) sensor 2.5 years ago, eventually my check engine light went out, then came back on for the knock sensor. When weather cools down in autumn and winter, check engine light goes off, in warmer weather, it comes back on. Anybody else? I also had a major issue of the car not starting when it rained (I wound up covering the hood of my car with a tarp until I could afford to take it to sears to get it fixed), saw several others with this problem, you need an entirely new distributor (not just the cap!).
Evap valve and canister needs to be replaced. Check engine light is on and now can only fuel vehicle very slowly or gas shoots out.
Check engine with code 1440, engine purge errors. Went to dealer, was told no problem, went on & off intermittantly, then after 10 yr emissions warranty is up I was told $1200. for a few solenoid valves, charcoal vapor canister, clean / replace lines, etc...was told that is common. Funny how it wasn't an issue when it was under warranty, same symptoms, same code, went on after 30 or more mins. of steady highway speeds when driving slower. Very funny how now it's a major issue when it was nothing to worry about..and was surely known the first time I took it in...
light comes on and stays on. no apparent problem comes up while the light stays on. should I get it fixed right away. ty daniel
Check Engine Soon light came on. I have one of those expensive, fix everything bumper to bumper warranties that I bought to cover these things when I purchased the auto. They say its not covered.
My regular mechanic will put it on for half what they charge and do the right job. I've been really diligent about service/maintenance at the Nissan shop, but I'll not darken their door again!!!!!
I was told this problem is occurring because I live on a gravel road. This was repeated by 2 different dealers and one hometown mechanic. When I purchased the car, there was no mention of not driving it on gravel.......... it's a 4WD vehicle. I was given a $700 repair estimate. My question is, if I have that done, how long will it be before the problem occurs again?
Service Engine light came and took it to Autozone to get the code. They sent me to another place who just reset the sensor and said it was probably a fluke. Came on 1 day later....
Nissan should have resolved these issues
their customer service is lacking
my dealership charges huge amount more for repairs than I see listed here and other sites
alot of issues with this car well over 5000 during past few years on repairs
engine light on all the time
tiny leak in the evac system
said 1000 to fix
may be vent door or something
but canister is rusty
just put gaskets in car over 1000 last year same month over 1000 for oil pan
wonder if pan seals not on tight and oil leaked causint the rust on gaskets this year
