View 3 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?
Golf VI R :: Code P0456 For EVAP System - Very Small Leak Detected
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?
View 11 RepliesGolf IV / Jetta IV :: EVAP Code (P0442) Small Leak Detected
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??
Golf IV / Jetta IV :: Check Engine Light Comes On - Code P0456 For Evap Leak
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.

Okay, so a few weeks ago, my tire blew out on the freeway. Of course my spare wasn't in there and when I got one I couldn't get the lugs loosened. My 4way was too big on all sides. It was late, I am a single mother of two young kids so I had no choice but to drive slowly to get it off the freeway. The next morning I came back fully prepared, got my car in to get a new tire. I have been driving with ONE code for my CEL, but at the shop (where I use to work) I used the scanner and it threw 5 codes.
P0300 Random misfire
P0442 Small EVAP leak detected (this one was already there)
P0420 Catalyst system below threshold bank 1
P0301 Misfire cyl 1
P0303 Misfire cyl 3
My beautiful love is an 02 Jetta 2.0 4 Cyl. Now, since 4 of these codes popped up AFTER my first blowout (I turn 30 next month, knock on wood)
Did driving my car at 5 mph about a mile and a half (everywhere up until the gas station was NO PARKING) do something to my car? All of a sudden, any in town driving ESP IDLING makes my check engine light blink and my car has no power I just have to pull over wherever I am. I checked the car out myself on the side of the road and my cat was glowing. After this I do not drive my car.
So, what should I do. I did a tune up. Should I replace the 02 sensors then the cat?
Passat (B7) :: Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent / Erratic
My 2.5L is throwing a check engine light with only 5000ish miles?!
P2407 - Powertrain - Auxiliary Emission Controls - "Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic"
I did a quick google search and apparently it MAY be due to a loose gas filler cap. I tightened it and drove around the block. Still on...
And (from the google search), this code isn't common with VWs.. (in fact, couldn't find a single VW with this code?).
Passat (B5) :: Check Engine Stays On Majority Of The Time - Evap System?
i have a b.5.5 V6 4motion and My check engine stays on the majority of the time. I've had a tech check the code and he tells me its my Evap system. The same tech told me that it was actually pretty useless to repair the problem unless the check engine light bothers me..

View 2 RepliesPassat (B6) :: CEL And Gas Cap Light Both Came On At Once - Evap Leak
I just got a 06 2.0T and my CEL came on about a week after getting it. I was driving home and the CEL and gas cap light both came on at once. I turned the car off and the CEL light stayed on. I just had the code checked and it came back as a Evap leak and misfire in cylinder 1. I was doing a bit of research and it seems like this is a common problem with these cars. As well getting a new gas cap never works. I have read that a smoke test is the only way to figure out where the problems is as well it could be the carbon canister by the gas tank. I know there was a recall for these when the cars first came out. Has there been a fix for this over the years or is it something I am going to have to trouble shoot?
View 2 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.

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 RepliesElantra 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).
Sonata I45 (YF - 2011+) :: CEL With P0456 Code - Small EVAP Leak
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 ?
View 9 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.
Jeep - 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 ?
