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 ?
New 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?
View 3 RepliesGot 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 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...
CEL came on after a couple of driving cycles showing code P0456 (evap emission control system very small leak detected)............. car drives fine has good gas mileage.....

View 2 Replies2009 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 RepliesWe 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.
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?
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 5 RepliesCheck 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).
My 2.5L is throwing a check engine light with only 5000ish miles?!
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 have an 06 sonata 2.4l--last week the CEL came on so I took it to my mechanic and he said it was p0455 which is a large vapor leak in fuel assembly. We tried tightening the gas cap and resetting the code with a scanner but it came back on a day or two later. I have never overfilled my tank and i do not smell gas anywhere. the only real symptom (maybe non related)is my speedometer , it works but it is just a little slow to react when increasing or decreasing speed.---my gas mileage seems to be normal.We got under the car and looked around and couldn't notice any obvious tears in any lines -- should i try buying a new gas cap?--I was thinking it may be speed sensor but my mechanic said if it was the speed sensor , my tranny should be shifting funny , my trans shifts fine. I am at a loss and don't want to have to go to dealer with this.
View 12 Replies2009, 89K miles ... As title states, check engine light came on today and after the codes were pulled, I got P0496. It was referred to as "Large EVAP system detected". I'm guessing this may have something to do with the fuel vapor management system but not sure what's a sure bet to check.
View 6 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.
Threw this code p0442 evap emission control small leak. I see its a popular code to have....
View 14 Replies2008 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 RepliesHas a P0401 code EGR unSufficient flow. Ive read several things that it could be, from a DPFE sensor to the EGR valve it's self our that the port going into the TB could be plugged. Truck drives fine does not have a miss or anything noticeable when driving other than the CEL, trucks a 4.6 with 200k on it. Forgot to mention it sometimes gets a P0455 code but i assumed that is gas cap. or could it be related?
View 7 RepliesIt 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?
