So at first I thought my code was 1101, lol, it's 0111. I've been getting this for a while now reset the ECU atleast 8 times and it always comes back. I thoroughly checked the vacuum lines running from the intake manifold, and also the evap canister purge control valve.

I'm assuming, the EVAP CPCV is bad, or the actual EVAP canister, the square box is bad. Any of you guys that have had experience with this and had to actual code please input what you did to eliminate the code/problem. What other components besides the EVAP CPCV, the EVAP canister, and electrical solenoid valve are involved in the evap system? If you can please just specifically list the part you replaced that made the code go away I would greatly appreciate it. Thanks!!!

 

?????????????????????????????????????????????????? ???????

 

Bump...I have the same code, still

 

i broke my EVAP Cansiter Purge Control Valve so I have to replace it...i have a CEL Light but i havent check the code...car runs fine....but I am gonna have to replace it soooooooon

 

Well I checked the EVAP CPCV and it was fine, no broken piece on that, all the little hoses running from it to, and to the tees also seemed fine. I checked the harness and connector looked fine.

I really wan't to know what people replaced, what parts specifically, that made the code go away hence resolving the issue.

 

ill check my codes when i get home.....and replace it and let u know

 

My CPCV went bad a long time ago. It didn't look broken. It was an easy replacement though and it got rid of the CEL. Just go buy the peice from the dealer.

 

I will definately replace that, I hope that's the culprit and not the charcoal canister. Did you also replace the charcoal canister?

 

Grrrrrrrrrrrrrrrrrrrrrrrrr, I reset the code, came back after 50 miles.

Okay so guys, should I do the EVAP canister first, or the EVAP Purge Control Valve.

 

Can someone please just give me the part #'s I can't seem to find them anywhere!

 

Guyss A PART # that's all I ask PLEASE!!

 

Okay, now I'm REALLY desperate. I replaced the Canister, AND the Valve on the canister. Not cheap $140 for both parts with a dealer discount from my buddies dad's shop. After driving 50 miles, the code 01 11 CAME BACK!!!!!!!!!!!!!!!!! WTFFFF. I thought the purge valve would be the culprit but I guess not . Guys I really, really need some help here.

Oh I also checked the fuse "ECCS" under the engine bay, and "ECCS 2" or whatever it was, fuse #57 and $58, both are GOOD.

 

Should I replace the 2 valves in the engine bay now ?

I already replaced the gas cap.

 

Okay I took out the Control Valve and the Purge Valve in the engine bay, the black piece and the silver looking piece with a harness on it. Both had charcoal in them, the black piece had a lot more than the silver one. I cleaned out both good. Put it back together, messed up once since I put the hose coming from underneath the frame parallell to to the fuel filter to the silver looking metallic piece, after looking at diagrams I saw that that hose needs to go the black circular thing. Well anyways, let's hope the code doesn't come back.

 

Did the code every come back?

 

Yes it did...

I replaced the canister and valve on the canister.

Still came back...

I have NOT replaced the purge valve in the engine bay, and the control solenoid for fear that it still won't go away.

 

Sorry to hear that. Looks like it is the code that just won't go away. I feel so lucky to have it and have inspection due.

I wonder if I can just get away with reseting the ECU and driving around for a while, but no over 50mph which when the EVAP code seems to come on. Hopefully the rest of the systems will be in "ready" status so I can pass OBD inspection. They will allow up to 2 systems to be not ready.

 

check your air intake duck the snorkel which conects to the box theres aseal on the part that connects to the box (likea foam seal) that would cause evap leak code i had the same problem traced it back to the air box brought some foam seal and problem sovled might be loose check the whole air duck system

 

aren't all emissions equiptment supposed to be warrantied forever??? maybe not, thought I heard that somewhere...

 

^ no way jose

 

you should have ohmed out the purge valve before replacing it. what exactly is that code?

 

I remember in the service manual you can download online, there is a rather lengthy list to problem solve that code. I know because I had the same problem and few people were able or willing to help. One thing, mine ended being the caused by my FSTB breaking a line.

 

Code is 01 11.

On nycmaximas.org someone suggested the control solenoid in the engine bay usually causing issues. I don't know, I just want it over and done with.

 

I don't understand what part you are talking about?

 

I think he's talking about where the 90deg piece comming from the snorkel(ram-air like thing)connects into the passenger side of the air box(where the filter is)

 

This is totally correct. There are about 7 or 8 different items to check. I started checking the first couple, but need to finish it up.

 

ahh this forum want let me post a thread (so its pretty much worthless to me know cant ask questions directly) so tryin this way i have a code 0505 on a 1995 max 5 speed, car started running ruff a couple days ago and now the engine lite came on so i got code 0505 witch means what? the list of codes syas this is nothing but my car runs bad now any ideas anyone?..thnx for any input

 

After replacing the solenoid and purge valve in the engine bay what else is there to check/correct?

 

I'd hate to say this, but gas caps go bad. Is your good?

Just a shot in the dark

 

That thing on the cansister behind the rear drivers side wheel is a bit pricey, but replace it too;

 

Already put on my buddies Nissan OEM Gas cap after an aftermarket one did not fix the problem.
