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.

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.

Toyota - Corolla :: Check Engine Light On / Small Evap Leak

View 5 RepliesPrius (2004-09) :: 2006 - Check Engine Light - P0420 Code / Air Leak In Exhaust
So today my CEL came on. I immediately looked at my mileage and I was EXACTLY at 500m past my oil change the other day. I checked the dip stick and lo and behold, it was about 3/4" past the full marker. I took it back to the oil change place and had them drain it down to a good level.
I had driven from NH to NY this week. I filled up my gas tank on my way home from NY. Gas cap was on nice and tight for sure.
The code is still on (not sure how many miles or drive cycles is required) for something to clear. I figured it was perhaps due to too much oil added. I decided a few hours later to take it to AutoZone and grab the diagnostic code. It's a P0420 code (Cat System efficiency below threshold: Air leak in exhaust before rear HO2S, AF Sensor Error, Fuel System Fault, Faulty Catalytic Converter).
Ford 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.
Prius (Gen 2) :: Check Engine Light Has Been Going On And Off - Evap System?
So, I have a 2009 IV, and it has about 60,000 miles on it. It's still has it's Toyota Certified warranty.
The check engine light has been going on and off for about 3 months. I hooked up my scan tool, and it says there were a bunch of codes popping up for the evap system. I did the obvious repair and replaced the gas cap (with a Toyota cap), and that worked for a few weeks, but the light came on again.
Since it's under warranty, I took it to the dealer and it turns out the vaccum switch (or maybe pump) for the charcoal canister was bad.
Struck me as a rather strange thing to go bad on a relatively newer Prius.
Anyway, had the water pump recall done while it was there, and hopefully all is good now.
Lexus IS 2014+ :: Check Engine Light Came On - EVAP Error
After only 1k miles after purchase my Check Engine light as come on. P0440 and one other (left the paper at work)
I haven't overfilled on Gas, the Gas Cap is completely on (2 clicks), and I haven't OVERLY pushed the car either haha.
The only update was replacing the STOCK filter with K&N Drop In Filter.
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 RepliesAccent LC (2000-05) :: Check Engine Light Code P0422 / Slight Valve Cover Gasket Leak
I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.
Santa FE SM (2001-06) :: 2004 - Check Engine Light Is On / EVAP Canister Solenoid
I have a 2004 Santa Fe 2.4L the check engine light is on and says about the evap canister solenoid. I am trying to located it but I can't find it. So, where would it be located at so I can take it apart and where is the Canister located as well...

Prius (2001-03) :: 2002 Check Engine Light Codes For EVAP System And Misfire
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
Toyota - T100 :: Check Engine Light On Due To Faulty Emission Evap Control Pressure Sensor
Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.

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?
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).

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 RepliesFord - 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 ?
