Ford Ranger / B-Series :: Occasional CEL Indicating Code PO442 - Small Leak Detected?
2001 Ranger-4 Liter-169,000 Odometer Miles ... Over the past year I would get an occasional CEL indicating PO442 Leak Detected (small leak). I would simply erase it. Now it's occurring more frequently at approximately 300 odometer miles.
There must be lots a places for a small leak to develop. But, I am thinking that there might be one or two places that are somewhat common.
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 ?

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??

P0456 - EVAP System: Very Small Leak Detected
Touareg :: 2004 VW V6 - Code P0456 / Evap System Very Small Leak Detected
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.

View 5 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.
Golf IV / Jetta IV :: Codes For Random Misfire And Small EVAP Leak Detected
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?

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.
View 12 RepliesFord F-150 (2009-2014) :: Check Engine Light Came On - Small Evaporative Leak Code
I have a 2009 ford f150 4.6l 3v v8 standard cab with about 53k miles on it.
Recently the check engine light came on so i went to autozone to have the codes pulled for free, it says i have a small evaporative leak.
They said may be the gas cap, but the thing is, i have a quick fill cap that came in stock with truck so the gas cap isnt even needed.
I've looked under the hood, and noticed that there is little pool of oil on top of the valley of the engine on the passenger side of the engine, could it possibly be the PCV hose that is bad and be related to the evaporative leak code? or its unrelated and i have a bad gasket for the valve cover?
It isn't affecting the performance of the engine,.. yet. I have a road trip for my work coming up very soon and i wanted to try to fix it before then.
Ford Ranger / B-Series :: Check Engine Light Came On / Code P1443
I have a 1997 Ford Ranger and my Check Engine Light came on a while back. So I eventually bought a scan tool and I'm only getting one code which is P1443. I've looked at both my Chilton and Haynes Manuals, my Ranger manual itself which is pretty useless for this problem, and I've been searching the internet like crazy.
From the threads I have read here it doesn't seem like a hard problem to fix yourself, and it seems like if you take it in anywhere they will charge you an arm and a leg to work on the EVAP system but it's an affordable do it yourself project.
I just don't know where to begin though, I see people talking about buying the complete set with hoses and the canister and sensor all together but I can't find all these parts. Where do I begin to repair the EVAP system?

View 12 RepliesFord Ranger / B-Series :: Check Engine Light Started Blinking On And Off - Code 327 / 328 And 334
I've got a 1992 Ford Ranger 2.3L with about 240,000 miles on it. The check engine light started blinking on and off pretty regularly so I pulled the OBD1 continuous memory codes and came up with this.
327 - EVP/EPT circuit below minimum voltage
328 - EGR closed valve voltage lower than expected
334 - EGR closed valve voltage high
I can't say these codes mean a whole lot to me besides I've got issues with my EGR valve and possibly the EGR valve position sensor. I was thinking I'd start by replacing the EGR valve.

Ford Ranger / B-Series :: 2007 - Check Engine Light Came On - P1633 Code
My check engine light came on the other morning after a rain storm. I took it to Auto Zone and they put their reader on it and come up with P1633 code. (Keep alive memory (KAM) voltage low).
The next morning the light was off. Couple days later it rained again and the engine light came back. Took it back to Auto Zone and checked it again to make sure it was the same code.
Seems like something might be getting wet unless its just a coincidence that it was raining each time the light came on.
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.
View 5 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?
