Intrigue :: Code P0442 - Small EVAP Leak
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.

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

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.
Golf 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??

View 14 RepliesAccent LC (2000-05) :: Error Code P0442 Indicating A Leak In Evap Emissions
This began as a troubleshooting exercise for a P0442 code (2002 model) indicating a leak in the evap emissions system. Often caused by simple things like a loose/poorly sealing filler cap. Not this time
It's a neat design, tucked away up in the fender well. Even sports a very effective stone guard (plastic shield) which hides all that tubing from view. But the shield also traps all the road salt and mud and packs it into the crevices between the tubes where it stays from one winter till the next. Even a powerful car wash probably can't dislodge the caked on mess once solidified.
Passat (B6) :: Evap Flapper Motor Failure And Charcoal Canister Error Code
An MIL light came on the dash the other week while driving. Dealer cleared the error code but next morning it returned. Car is now in the shop to have the flapper motor and canister can replaced. Get it back tomorrow, Got '08 Jetta 2.5 as a loaner. I will run out of warranty in another couple of weeks(48100 mi. on it now).

View 1 RepliesFord Super Duty (1999-2016) :: Fault Code P0442 (EVAP) Be Caused By ESOF Vacuum Leak?
I have 2 issues and wonder if they are related. I don't have a CEL but I'm getting a P0442 DTC with my code reader - EVAP system leak detected
Also, my ESOF doesn't work. The hubs will lock manually. Can this be related?
I've already cleared the code and it came back. My ESOF hasn't been working for a while but I just haven't had the time or motivation to look into it until now.
I tried the HVAC Test and there may be a slow leak in the system. I can get the vents to switch from defrost to face vents but it switches halfway back to defrost, both are on at the same time for 20 seconds, then it recovers and goes back to the face vents.
My 4wd relays seem to work as well.
Ford - Explorer :: 1999 - Code P1451 EVAP System Canister Vent Solenoid Circuit Malfunction
I have a 1999 Ford Explorer with the V-6 SOHC that is stuttering and stalling when I try to accelerate. A very slight acceleration will get the vehicle moving, but anything coming close to normal gas pedal pressure causes immediate stuttering and/or stalling. Check Engine light came on when problem started yesterday.
Where is the EVAP System Canister Vent Solenoid? I bought a code reader after beating my head against the truck all afternoon and got code "P1451 EVAP System Canister Vent Solenoid Circuit Malfunction". My Haynes book says on the left side frame rail... can't find anything along there that looks like it (based on picture from Rock Auto for replacement part) and found some people online talking about it being in the engine compartment on the passenger side...
Just crawled all over the truck and I think I found the charcoal canister, but couldn't trace it back to the vent solenoid... There was something right next to the canister, but again, it looked nothing like the replacement part listed on Rock Auto...
Ford Super Duty (1999-2016) :: 2009 F250 - Code P0442 - Minor EVAP Control System Leak
My 2009 F250 5.4 was throwing code P0442 - minor EVAP control system leak.
The first time it happened, the guy at the parts store checked it out, reset it, and said if it comes back, try replacing the gas cap.
The second time it happened, same thing.
I bought a Stant cap at my local parts shop, and had them reset it again. I don't like the Stant cap since it does not fit the retainer correctly, but it sealed fine.
However, the same code came back.
It took a smoke test to identify a leak from the vent tube on top of the fuel tank. The tube was replaced today.
If the code stays gone for a few hundred miles, I'm going to switch back to the original gas cap. I want to make sure the leak is gone before I change anything.
Ford Wiring/Electrical :: P1451 Code - EVAP Control System Canister Vent Solenoid Circuit Malfunction
I'm not too knowledgeable about wiring and electrical systems. I'm getting a P1451 code (EVAP Control System Canister Vent Solenoid Circuit Malfunction) on my 99 4.2. I've read that it could be a bad solenoid, bad wiring, or a blown fuse. So far I've;
- checked (and changed) the related fuse
- checked the wiring for damage at the connector
- checked voltage at the connector (12 volts)
- checked the resistance at the solenoid (around 60 ohms)
- actuated the solenoid with a 9V battery (can hear it opening and closing)
I haven't had a chance to check the wiring all the way back up the frame to yet, but I noticed that the ground at the trailer wiring harness has broken off the frame. Would this potentially cause a fault in the upstream wiring? I'm going to slap a new connector on and bolt it back down anyway, but as it's Labour (Labor) Day I'll have to wait for the stores to be open tomorrow.
Prius (2004-09) :: Multiple EVAP Codes - Canister On Top Of Gas Tank Is Bad
I took my 2008 prius with 183,000 miles in last week to have recall work done on it. they did the following:
1. Accelerator pedal recall
2. Steering shaft recall
3. Hybrid Electric water pump recall
The following day when I start my prius my check engine light comes on so I figure it was something they did on the recall work. I do have a scangauge, and the only code that showed on it was a P1304. I took it back to dealer today, and was told that it had multiple EVAP codes, and that the canister on top of gas tank is bad, and will need to be replaced. They said it was full of gas. They asked me if I stopped fueling car when pump shut off? I told them I always go to next whole dollar. They said to always stop as soon as pump shuts off(but on some pumps they shut off like crazy when pumping gas), I told them to just clear codes, and I would get back with them if I decide to have canister changed. So far check engine light has stayed off ( dealer is about 100 miles away)

View 2 RepliesFord - Explorer :: 1994 - Missing Connector For EVAP Canister
I'm converting the automatic in my 94 explorer to a M5OD-R1 five speed transmission. I got the manual wire harness from the donor truck and it plugs into the existing connectors, but it's missing a connector for the evap canister. Should I just use the automatic harness and modify it to bypass the clutch safety switch and wire a switch for backup lights? Or use the manual harness and wire the evap canister to the ecm? I'm not much of an electrician, just trying to find the correct way to do this so the truck runs good.

My CEL came on and I took it in to dealer. They replaced the EVAP line and purge valve. My CEL came on again that same week and supposedly it detected a small leak (sporadic, same code as previous), they ran test and did not detect any leaks. They finally told me that I might have to replace the canister if CEL comes on again for same code.
View 3 RepliesChevrolet - Silverado :: 2009 - CEL Came On For Code P0442
The CEL came in on my friend's Chevy Silverado .....so he took it to the dealer for diagnosis/repair. After paying for the diagnosis and repair (supposedly he needed a new gas cap) he was good to go. A few days later the CEL came in. I have a code reader so he asked me to check the CEL code. It's P0442. The same code that the dealer sited. Since we know it isn't the gas cap what are the other most likely suspects? He says the truck runs fine. No drop off in MPG, no misfire, etc.
View 2 RepliesCamry :: Error Code P0442, P0442P And P0456P
I've been getting P0442, P0442P and P0456P on my 2005 Camry 4 cylinder standard since about December 2011. For some odd reason, lately P0456P stopped when scanning when the CEL comes on again after erasing the code.
There's no symptoms of any problem so I think it's likely to be some small leak in the evap. Looking at my gas cap, it's a little dirty, but I don't see any cracks or damage, and I always make sure to fasten it on tight.
I have emission test coming up soon. (Actually this happened for 1st time like about 4 years ago when the car was under warranty. The dealer simply said that I didn't fasten on the fuel cap right, and erased the codes and sent me home. After about 4 years, same codes now that the warranty has expired....)
Avalon 2005-12 :: CEL Error Code P0440 Error Code / Charcoal Canister Replacement
So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.
