2003 passat GLS stock w/ 1.8T, MIL comes on after full tank drops to about 3/4 full. Code 16826 will clear but keeps coming back, always when the tank is about 3/4. I have replaced gas cap but, no luck. Also, sometimes after filling the tank the light goes off by it's self.
View 2 RepliesPassat (B5) :: MIL Came On - Code P0455 / EVAP Emission Control System Leak?
New owner of a 2003 1.8TPassat (29,000mi) as of the last 2 weeks and have just had my MIL come on. Scanned it at home with my Actron CP9125 scanner and got this code (P0455) which reads in the scanners manual as "EVAP Emission Control System Leak (Large)". Didn't know if this was a generic description of the code or VW has a more specific definition. What precisely this is in reference to, gas cap, vacuum hose????? Or what VW's actual description of this code is?

I've gotten the P0442 "small leak - intermittent" code and "service now" warnings on my 2007 2.0T Passat. I have also occasionally gotten the "check gas cap" warning and icon on the dash, but it always goes away quickly. The car runs fine. The VCDS scan shows as follows:
Address 01: Engine Labels: 06F-907-115-AXX.lbl
Part No SW: 3C0 907 115 S HW: 8P0 907 115 B

P0442 - 001 - Small Leak - Intermittent
[Code] ....
If I clear this code, it comes back within a day or two of driving, but not immediately. I have already replaced the gas cap and N80 valve. The other component I'm aware of possibly failing is the check valve. It's just downstream of the N80 valve, circled in red here:.
I put a vacuum on this part, and it had a very slow leak, losing about 3psi (starting from 20psi) every minute. That seems too small a leak for this to be a problem? Is this thing supposed to be absolutely air tight? Since this part is more expensive ($80) and bit more hassle to replace than the N80 valve, I'd like to know more about this before I just blindly replace it.
If this check valve isn't the problem, then what to check? Although the car runs fine, I need an inspection and would prefer to not have to clear the codes and hope for the best just before taking it in.

View 14 RepliesPontiac :: Check Engine Light On / Evap Leak Code?
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.

View 12 RepliesFord Ranger / B-Series :: Check Engine Light Came On - Code P0457 EVAP Small Leak Detected?
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.

Passat (B7) :: Check Engine Light Came On - Bad EVAP Purge Valve
I only have 2200 miles on my new 2012 Passat SE V6 and the check engine light came on the other morning. I took it in to the dealer and they found codes P0442 (EVAP Emission Control System Small Leak Detected) and P0456 (EVAP Emission Control System Very Small Leak Detected). The tech says on the work order that he removed and tested the EVAP Purge Valve with a vacuum pump and the valve would not hold a vacuum. The dealer replaced the EVAP Purge Valve under warranty. They say this is the first 2012 passat V6 they've seen with this issue. I've only had the car for 4 weeks.
View 5 RepliesSanta Fe (CM - 2007-12) :: CEL Is On For EVAP Leak
The CEL is on for a evap leak. I replaced both packing O-rings for the fuel pump, which I should have done when I replaced the fuel level senders. I have driven the car for a week with no resolution. I did try a new gas cap before I replaced the O-rings, but it didn't resolve the problem. I realize that I may have more than 1 issue, so I'll put the new gas cap on shortly. Just wondering if there's anything else I should check before I put the seats back. Are there any other common areas to fail that I need to check?

So I have had this code P0442 for a long time and I just kept clearing it. The attached picture (at an angle) shows the hole in the small line attached to the fuel neck filler exactly behind where the plastic wheel well cover touches it. Just ordered a new one from rockauto for about 65 shipped.
View 5 RepliesGolf IV R32 :: EVAP Leak Detection Popping All The Time?
I know the EVAP Leak Detection system is supposed to pop and click on start-up, but from what I've read it goes away after a few minutes (after the system pressurizes?) - however I've been noticing my popping still happening after 10-15 minutes of driving (I believe it sometimes even pops when I shut off the car)... I am not getting any warning lights. Is this normal?
View 2 RepliesGolf IV / Jetta IV :: CEL Code For EVAP - Very Small Leak
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?
Elantra XD (2001-06) :: Code P0455 / Large EVAP Leak
Check light came on and I had the code read at AutoZone. There were 3 codes but I'm pretty sure 2 are old (the check light previously came on a couple of months ago and I had it checked, then went off on its own). My car seems to be driving fine.
The new one is P0455. Large EVAP leak. I'm hoping it is just my gas cap.
The other 2 (older) codes are P0456 (small leak) and P0113 (IAT error).

View 9 RepliesJeep - Liberty :: 2003 - Intermittent Small EVAP Leak
I drive a 2003 Jeep Liberty Sport, with the 3.7 liter V6. It has roughly 97,000 miles on it.
In the year or so that I've owned it, the jeep's check engine light has come on several times. Every time I've had it checked, it's the same issue - a small evap leak, code P0442. Typically, they'll reset the computer, and I'll drive it for two or three months and eventually, the code will come up again.
Oftentimes, I'm told it could be caused by a loose gas cap. I'm aware of that and I try to make sure it's nice and tight every time I fill up. I've also looked at it, and there are no visible cracks or holes in the cap itself. But, the problem still occurs.
So, What this could be besides a loose gas cap, could cause an intermittent small evap leak?
Ford - Escort :: Code P0455 (Gross Evap Leak)
Car has about 75K miles. Son has the car out of town (again), at school. He reported CEL (SES?) light on; "what should I do?" Told him to have it checked. He has trusted mechanic nearby, so I told him to go there. They say they don't just read codes ("You can get Autozone to do that"); they do diagnosis.
Report: Code P0455 (gross evap leak). Did smoke test; nothing. "Did you maybe have it running when you filled gas tank?" (No.) They reset the CEL, and sent him on his way.
Should we be satisfied if CEL stays off? What else to try or to look for if same code comes back?
Sonata NF (2006-10) :: P0456 Code - Small Evap Leak Detected
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 ?
