Golf IV / Jetta IV :: Check Engine Light Comes On - Code P0456 For Evap Leak
Oct 14, 2015
I have a 2005 1.8 TJetta GLI owned for about 2 months now. Gas cap warning pops up then goes away when I turn off the car then check engine light comes on. I've change the gas cap to new oem one changed the purge valve [URL] .... After a couple of weeks same issues again brought it to my mechanic he ran a leak detector and told me that there are Evap leaks. I read somewhere that I might need a need charcoal canister and a fuel tank.

It all started with a fuel cap loose light (it wasn't) after a day or two the MIL came on and got this code I reset it but I'm sure it'll come back since there's probably a real leak. What can I check myself to find this leak?

I've had a check engine light on in my 3.5 Pontiac G6 for awhile now. It's an emission code (can't remember what code but evap leak). The solenoid by canister was also tripping a code that disappeared after I changed it. However, the evap code still persists. Last night while changing my oil I noticed the intake air hose to the crankcase had broke at the case and wasn't connected. It's the hose that runs from the engine intake to the crankcase for the PCV system.
I am replacing the hose regardless, but my question is; would the intake hose for the PCV system being loose cause an evap leak code? I am thinking no but it'd be nice if it was that simple.

Wife's car had a check engine light this morning, code is PO456, small evap leak, I took gas cap off cleaned the filler neck and solenoid the gas cap seal, and reset the light. I filled her car up on Sunday (2011 Sonata 2.4 80000 miles). Where to go next if light comes back on? Purge valve ?

My 2007 Sonata continues to throw a P0456 code, small evap leak detected, gas cap is tight, getting ready to check the evap hoses. The question I have is the evap system covered under the emissions warranty at all ?

2009 santa fe 67000 miles. Replaced fuel senders approx a month ago. All was fine. On about the 3rd fill up the cel came on. Code was for small leak evap. checked the gas cap, no problems. Replaced the purge valve and disconnected the battery while doing so. Cel light went off and stayed off thru one tank of gas. Filled up again and thought I detected a little fuel smell shortly after and cel came on again. I only smell fuel when its full and down to just before 3/4's. The light came on right before 3/4's. My husband is beyond frustrated and wants to smash the car lol. Once I get him calmed down where should we be looking for a leak and how to fix it? We can't afford a dealership bill right now and of course it's due for inspection next month.
Code was p0456
The only answer I got in the DIY section is to check around the fuel senders again but I'm leery to do it as I can't see how there would be a leak there, the covers go on SO hard even with that tool.

I had a check engine light cane on. I took it for it to get checked and they gave me this code- P0457 EVAP small leak detected. ECM has detected a large leak in the EVAP System during a system monitor test.
The paper said I had a leak in the Evap canister or hose. I took the truck to a mechanic and was told I had Bad oxygen sensors. Can Bad/Dirty oxygen sensors make this error code come up?
Exactly where the oxygen sensors are? I was told they were behind the mufflers but I didn't see any and the diagram I found was not accurate.

P0456 - EVAP System: Very Small Leak Detected
View 8 Replies
2004 VW touareg v6 - engine light on - autozone diagnosed as code P0456. Possibly gas cap, so I replaced with aftermarket gas cap from auto zone. Light still on. What can I do or replace to fix problem. I read something about a N60 or N80 valve. Is this something I can buy and replace myself. Most of my mechanical experience is related to working on a 85 CJ7 with an inline 6cyl or Chevy trucks. If the N valve is a easy fix, any instructions and pictures of how to do this.

Got a CEL tonight while driving. Originally I was driving and the light came on saying that my gas cap was loose. I corrected the problem when I got home and tightened again. The light stayed on however. I ran a scan with the OBDII and it gave me a code for EVAP- Very Small Leak .
I was reading around and some people suggested the MAF. Which would make sense because I recently had all of that stuff off and gave the engine a deep cleaning while it was exposed. I just don't see how the MAF could relate to the code my car is pushing?

so my girls car is throwing an evap code (P0442) small leak detected. I bought a new oem gas cap and replaced the purge valve solenoid under the hood. that didn't work, CEL still comes on about 100mi after clearing the code.
I have checked the rubber hoses that were attached to the purge valve solenoid when i replaced it and they are fresh, no dry rot or cracks that i can see. The hose on one side goes to a hard line that runs under the car to the back, the hose on the other side of the solenoid runs under the intake to the throttle body. That hose was fine as well. Connections were tight and i even put better clamps on the hose ends that attach to the solenoid. So I have ruled out that portion of the system (under the hood).
I also removed the rear seat to access the fuel pump. All those connections seem nice and tight, I don't smell any strong gas fumes indicating a leak so i don't think the fuel pump gasket is the problem either. Finally, i checked out the hard lines running under the car front to back and I see no apparent or obvious damage. I assume my next step is to pull off the rear passenger wheel well liner and asses the charcoal canister and the LDP connections, correct??
The last thing I will mention is, Idid notice the 2 fuel lines that attach to the fuel regulator are in pretty rough shape, however not leaking any fuel. Are both of these lines actual liquid fuel lines? I am thinking one of them is a vapor return which may be part of the EVAP system. If it's dry-rotted and leaking vapors could that be the culprit??

At roughly 140,000 miles, my wife's '07 Santa Fe GLS has thrown a P0456 code. Does this code on a Santa Fe common?
It is "evaporative emission system leak detected (very small leak)." The good news, I guess, is that it is 'very small.' However, being small may make it more difficult to detect.

My CEL came on a few weeks ago on my 2010 gti, I scanned it and got a code for evap (P0456). I figured it was from filling the tank while the car was running, so I cleared it and went on with my week. About a week later it came back on and when I scanned it, I got the same thing. I haven't had time to smoke test the system but the last couple days i have heard a clicking/tapping noise coming from the rear passenger side of the car. Could the flapper in the filler neck be malfunctioning or gas cap be leaking.

MK4 GTi - My check engine light came on a few days ago and when I checked it, it pulled code P0420.
Just this morning, the check engine light went away.
Is this a common issue? Or should I go get it checked just in case?

Just installed a short Ram intake on my 2000 Vw Jetta 1.8t. Had the Intake for about 250 miles and now the check engine light came on. Just pulled the code p0411 secondary air injection system incorrect flow detected. Is this just cause there is more air going through the MAF sensor?

I have a 2000 jetta 1.8t. Check engine light recently came on and the code is a PO1128. I replaced the maf sensor and that did nothing but make the car run worse. I've check for vacuum leaks and found a busted line at the egr valve, fixed the line, reset the code only to have the check engine light come back on with the same code. I am at a loss now.

Bought a Mk4 1.8T gti last year had only about 75,000 on it and drove it for about 10,000 miles. The check engine light went on about 2 months ago and the code read 3rd gear incorrect ratio. It still rode fine until about a week ago when it started slipping. Brought it to the local transmission guys in my town and got a quote at about $3,000-$3,500 to have the transmission rebuilt. The transmission is a tiptronic automatic 6-speed.
