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.

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.

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 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....)
Volvo :: Getting P0442 Code Periodically - Wrong Evap Canister?
I've been getting a P0442 periodically from my 97 850 wagon (base, no turbo). I've replaced the gas cap, the electrical part of the ignition switch, and all the deteriorated rubber vacuum-hose couplings I can find under the hood, but I'm still getting the code. I want to inspect the hose couplings at the evap canister, but there doesn't appear to be any way of getting to them other than removing the canister from under the car. Is there any other access to these?
Also, I've got VIDA running on my PC, and even though I've given it the VIN, it shows me the wrong evap canister in the parts diagrams. It shows the cylindrical canister, but my 850 has the rectangular canister. Where I can view accurate diagrams showing the evap components in this car?
Santa Fe (CM - 2007-12) :: 2009 - Error Codes P0464 And P0442
My wife has a 09 Santa Fe and we were getting code p0464 fuel sensor circuit intermittent. I changed both parts that need replacing. After about 20 miles now code p0442 small evap leak detected. I can only assume that it is coming from the fuel sensors that were replaced. Is there anything that I could have screwed up on?
View 1 RepliesGrand Prix :: SES Light On / Small Emissions Leak - Code P0442
About a month ago I had my SES light go on and I took it to the auto parts store and they said it was a small emissions leak. I am not sure of the code though. I took my car to the shop and they said that a sensor that had something to do with the exhaust was bad or unplugged.
My SES light came back on about about a week ago and I had it tested and it said the same thing. "Small emissions leak" This time I got the code and its P0442. The shop is closed today and tomarrow so what and where the sensor is located? Or if its the same thing?
Passat (B6) :: Evap Small Leak Intermittent Code P0442 Strikes Again
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:

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??

where best place to start looking for what's causing p0442 code on my 2005 rx330? and its not the gas cap... also have a "c" code identified for the VSC light, states that its wheel speed sensor. evidently wrote the wrong code down, i had it listed as a c1290 but in looking them up i couldn't find that one.
View 6 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.
Camry :: OBD Code P0442 - Small Leak In Evaporative Emission Control System
Got an engine light on today and had it checked at Advance Auto. It is P0442, "small leak in Evaporative emission control system". One article I read said to remove and retighten the gas cap, clear the code then see if it occurs again. If it does then replace the gas cap with a new OEM cap, and try clearing the code again to see what happens, as a first step in the troubleshooting process. I retightened the gas cap, but don't know how to clear the code and turn off the engine light.
View 3 RepliesPontiac - Grandprix :: 2002 - Service Engine Soon Light Has Been On / Code P0442 And P0128
Got a 2002 GT with the NA 3.8 and 150,000 miles. The car has pretty much sat for the past 6 months, driven very sparingly. If it's been sitting for a while (like over night or longer) it will start no problem. If I turn the car off for a shorter period, it will crank but not fire. It will start only if I pump the gas as I'm turning the ignition.
In addition, on occasions it has died while at idle or coasting to a stoplight. After it dies it will fire back up no problem.
Fuel problem perhaps?
The "Service Engine Soon" light has been on for about a month before it started acting up. I had the codes checked at AutoZone and it came up with P0442 and P0128.
Ford Super Duty (1999-2016) :: Code P0442 On 2003 V10 - Purge Valve Solenoid?
CEL turned on this morning heading to work. Truck drove completely normal with no signs of altered performance.
Stopped by Autozone after work and they checked it with a code reader.
Came back with P0442 - "Purge Valve Solenoid"
Part sold with or without bracket.
Is this a common part to fail? How can I be sure it has truly failed? Is it acceptable to reset CEL and see if it fails again? If so, how do I reset? Where is part located?
Ford 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.
