2009 Impala, 50000 miles, runs good, however service engine light is on with a DTC showing P0455, "Evaporative Emission System Leak Detected, Gross Leak/No Flow". Are there obvious things I should search out or has there been a common problem in the EVAP system on this make and model that would pinpoint the leak?
View 19 RepliesI have a 2008 Chevy Equinox, and recently I noticed a gas smell...I saw Chevy had a special policy to replace the fuel pump module, so I took it to the dealership hoping that would be the problem. Fortunately it was, and they replaced it for free. I got my car back Thursday afternoon, drove it Friday, and it sat yesterday without being driven. This morning I drove to the grocery store, and on the way home my check engine light came on. I have an ODBII scanner, so I plugged it in and got this code:
P0455: Evaporative Emission System Leak Detected (gross leak/no flow)
So I was wondering: (1) what is the cause and/or solution to this problem, and (2) is it possible the dealership caused this problem when they replaced my fuel pump module?
It seems awfully coincidental not to be related to the repair, since it is a fuel system problem, but I don't know enough about cars to be sure...
I have a 2006 Mitsubishi Lancer and CEL is on, I got the code checked and its showing P0456 ("Evaporative emission system very small leak"). They recommended that I replace the gas cap, but I already tried that without luck. I have heard that the tubes in the system go bad and need replacing. I know some are located behind the back wheel but I wanted to give the ones under the hood a visual inspection so I have some clue when I take it for a repair.
My trouble is that I don't know what tubes I'm looking at! But I have some pictures, so at least we have that!
So the first one is zoomed out of the engine (obvious right?), just so you can see where everything is going. The hose I'm suspect of is the one that's to the left of the motor oil cap, the one I'm holding in the second picture. If you can see it, there's a split running down for about 6" -10"
What I'd like to know is did I assume right that this is (at least one) of the hoses causing my trouble with the evap system? And if it's not, which ones should I be checking out?
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.

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?).
I own a 98 f-150 5.4 with 70,000 miles. I get a check engine light (code p0455-large leak detected in evaporative emission control system).
Replaced the gas cap with an after market 'stant' ( I believe was the manufacturer) brand. The check engine light went away for 4 days then came on again.
No obvious vacuum line leaks.... Puzzled.
I have some codes on my ranger 2000 here goes
P0141: o2 sensor heater circuit malfonction (bank 2 sensor 2 )
P0455: evaporative emission control system detected (large leak)
Now I will need to get that fixed cause I don't know where to look and what to look for ... For the leak I know there is a big crack on the plastic where the gas lid is could that be it ?
We are selling the girlfriends 01 Passat. I pulled the codes tonight for a long standing check engine light knowing it had one of the 02 sensors bad. Here are the three codes I received from the scanner:
P0130 - 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0455 - Evaporative emission control leak detected (large)
P0441 Evaporative Emission Control System Incorrect Purge Flow
So is it one thing causing all three or are there common things to look at. We can't really afford to go replacing all the emission system sensors and hoses etc. in hopes of finding the right piece. Gas cap is screwed on tight and codes were cleared a couple times to make sure.
The check engine light on my 99 Camry went on at about 180,000 miles. My mechanic checked the code and turned up an EVAPORATIVE EMISSION CONTROL SYSTEM INCORRECT PURGE FLOW He said this could be any number of things,including the need for a gas cannister or some type of valve. What does this mean? How do you determine exactly what the cause of the problem is? What are the likely fixes? Will Toyota be able to better determine the cause than my personal mechanic? What are the best options?

View 2 RepliesI have an 07 Impala. Just recently, the engine light came on. I contacted OnStar who did a vehicle diagnostic and told me the problem was the emission control and further told me I should tighten my gas cap which might take care of the problem. It didn't. How important is it to take care of this?

View 7 RepliesI have had issues for over a week now first problem check engine light not sure of the code but the mechanic said it was the spark plugs and vaccum leak hose (which I knew about the hose). $205.00 later replaced all 6 plugs and hose. Now today on way to work I'm getting that hesitation when in lower gear such as stopping and then accelerating it jerks some it was doing this alot before replacing the plugs.
We did a diagnostic code reader and it said the code P2402 I did read it could be my gas cap which I don't have a dealer gas cap on there now I did about 1 yr 1/2 ago but got a lock key gas cap instead. I have been doing some reading I would need to replace leak detection pump which apparently costly in repair.
BTW car has 119,000 miles I commute far from work 5 days a week. My car is very important part of my life! I did also read someone stated there was a recall on Mazda 6 wondering do I need to call the dealership to see if this is actual recall and I can cross my fingers get this fixed on them.
2008 with 165K. I had the fuel pump replaced then started getting this code. Garage said they did a smoke test could not find any leak. I then replaced this part (CCV #31453-3K500 / picture attached) I still get the code.
View 2 RepliesNew owner of a 2003 1.8TPassat (29,000mi) as of the last 2 weeks and have just had my MIL come on. Scanned it at home with my Actron CP9125 scanner and got this code (P0455) which reads in the scanners manual as "EVAP Emission Control System Leak (Large)". Didn't know if this was a generic description of the code or VW has a more specific definition. What precisely this is in reference to, gas cap, vacuum hose????? Or what VW's actual description of this code is?

I have major oil leak which starts leaking when the car is running, i cannot see from the top and when i am underneath the car , I cannot see far enough up in the there to see where it is leaking, It is not coming from the seneding unit or the oil pan,,when the car is running it just pours out oil.
View 3 RepliesI have had to disarm my alarm system in my 2003 Impala (done via the radio) due to what appears to be a flaw in the system. It is telling my car I am trying to steal it and thus it won't start. As soon as I turned the "alarm" system off the car started right up. From my research this seems to be a consistant issue with this car. My question is by switching off the alarm system, am I doing any long term/short term damage to the computer system/car? I have a scheduled appointment for later this week with the dealership, but from what I have read on line (going back to 2007) the car maker is aware of this glitch and has not been responsive in fixing it without being paid. I bought a warranty when I got the car back in Dec of last year, but not sure if something like this would fall under it's coverage. If just keeping the alarm system turned off allows me to start and drive my car without damage, unless they plan on fixing the glitch for free I can't see spending the hundreds of dollars I am reading it will take to fix it.

View 7 RepliesOk so my car kept overheating and I saw I had a small leak from the gasket on the water pump. I replaced the water pump and gasket but then it would zoom straight to overheating. I then assumed it was a stuck thermostat and replaced the OEM with a fail-safe thermostat. After topping off fluid and leaving the radiator cap off until I saw fluid running through it took it for a drive. The temp began to climb to overheating but dropped just as it was getting to the red and then began to fluctuate. Finally heat came through the car climate system and all was good until I had to come to a stop. It seems that whenever I have to stop at a light the temperature rises to overheating.
View 9 RepliesI 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.
