Chevrolet - Equinox :: Check Engine Light Is On For Evaporative Emission System Leak Detected
Aug 10, 2014
I 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 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 ?

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?

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.

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 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.

1997 Lincoln Town Car, We had an accident three years ago in which the right rear wheel was destroyed and the axle bent. They were replaced. . Shortly afterwards the check engine light (emission leak) came on. My local mechanic thought he found and repaired the problem. It came on again. We changed the gas cap. No dice. The local Lincoln dealer did a smoke test and decided the problem is the SOLENOID ASSEMBLY CANISTER VENT. But the part is obsolete. An after market part did not solve the problem and neither did a used part the dealer installed. The car operates normally but I won't be able to pass inspection.

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.

I 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?

Our 2008 Equinox with roughly 90K miles showed the "service stabilitrack" warning on a Friday, next day light was still there now paired up with "check engine" light. My husband did something to the "stabilitrack" button which made both lights go away for a couple of days. Then both of these returned. Took the vehicle to the dealer (we always do for service, we just don't know some good mechanics in our area and so far we had not had any major issues with the vehicle).
They tell my husband it is the EGR valve that supposedly needs replacement and that the reason it got to be bad is because we failed to maintain / clean the fuel injectors so those need to be washed / cleaned / serviced too so that the whole issue is resolved. No mention about the "stabilitrack" thing at all. Due to our needs of the vehicle and our lack of cars knowledge we agreed to it without looking into it further.. Lights have been off since that and we didn't think much of it.
But then this weekend we got this "recall" letter in the mail for that very same vehicle... talking about the "check engine light" being the issue and an apparent leak of gasoline (via odor or visual leak)... Maybe these are totally unrelated ...
I checked the manual for the recommended maintenance and nowhere there is mention of regular maintenance needed for the fuel injectors.. I looked online and while there seems to be varied opinions most of them agree that is something not needed; neither it is the EGR valve replacement... so now I am really wondering! Was it all for nothing? And how is one supposed to know this. Is the "check engine" light enough of an issue to maybe think this was the right thing to do?

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?

So mad today. Check engine light came on, plugged in my scanner, got P0441 EVAP Emission Control system Purge Flow Fault and P0455 EVAP Emission Control System Leak (Large).
8-month old '13 TCH XLE is getting a check engine light already.

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.

I 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.

I have a 2007 Camry V6 with 49K miles. Yesterday the Check VSC System lite came on along with the check engine light and picture of a car with tracks behind it. The car runs perfect. The engine is smooth, no misses, and no other signs of any kind of problems. My wife drives this car about 6K miles a year. Took it to AutoZone this morning to check the codes. The first thing that came up was Fuel Injector Pressure Regulator. Then codes P0301,02,03,04,05,06 each saying Misfire Detected. Also code P0352 Ignition Coil B Primary / Secondary Circuit.

I have a 2006 equinox with 74000 miles that consumes up to 2+ quarts of oil every 2000 to 3000 miles between oil changes and the water in the fluid section of the car drops about one gallon of water thus causing the car to over heat what could be the problem. The engine light always comes on when i have more or less then 1/2 a tank of gas. The manual said this could be the gas cap that is producing the problem and is there a solution.

Went in due to the check engine light coming on and found out I had a oil leak in both oil cooler lines they wanted to charge me 350 per line and 200 for labor which brings the total to 900. Are they over charging me if not is there a cheaper fix for them? 2007 impala 3900 v6....
