Make sure the line from the canister to the purge valve isn't cracked or has a hole in in. You will still get the code. Perform a visual inspection of the line .
to reiterate, the Jeep is a 2004 Liberty, 6 cyinder engine. the gas cap and evap purge valve have been replaced, no other codes show when I check the ignition. Just P 0441. I have visually checked the lines and no visible cracks anywhere. The purge valve was checked before replacement and it wasn't holding any pressure after testing it.
Thank you for the lesson. My car has an purge valve, but it is a straight tube from canister. Canister itself has no sensors and the tank has no sensors also. It is an 2003 Skoda very basic. Now I have the p0441. I can only imagine an defective purge valve. But how the ECU knows that it is defective? It measures the output current to the solenoid?
Great to watch your videos. I've cleaned out the p0441 code and i replaced the purge valve and cleaned the gas cap as well, but still get the code p0441. I'm driving skoda Superb 2.0 2011
Hi Gabriel, please try looking for any disconnected or damaged wires within your EVAP system and repair/replace it to see if the issue will continue to persist.
2007 Toyota Sequoia check engine light lit up and the other lights as well. Gas cap has been changed, gas cap always is tightened correctly. Now I am told that the Purge Valve is making the check engine light up, nothing to do with the gas cap. The Purge Valve will cost $350-$500 to replace next time the check engine lights up. ~ Fort Smith Arkansas
Yes, that's the most common cause that triggers the code. We also suggest checking if there's an issue with the related wiring, vacuum line going to the purge canister, purge control solenoid and if there's a vacuum leak.
Hello, do you still get this code when its tightened already? Check also the other factors that triggers this code like: purge control solenoid, wiring issue to the purge solenoid, vacuum line going to the purge canister, and the vapor canister purge valve.

Hello Steve, I have 2004 Lexus Is300 that has error codes P0441, P0442 and P0446. I brought it to a mechanic a few years back regarding these codes. Would like get advice and see if this can done by myself before bringing the car to a shop again. Thanks
I have a 2021 silverado with evap pump underperforming code. I have replaced the valve solenoid but still getting the light. This truck doesnt have a gas cap. What could be my next step?
I have 2006 Toyota Avalon just did my emissions and failed due to codes P0333 knock sensor circuit high bank 2 And P0441 Evaporative System Incorrect Purge Flow I changed the gas cap 3 years ago and didn’t fail my last emissions test Any advice?
Hello, a stuck PCV, short circuit (in the feed circuit), or a faulty purge solenoid could be triggering the codes. Kindly have them checked and fixed to see if the issue will still persist.
Just got the p0441 code 3 days ago and gas cap is fine and when I did the canister purge valve test, I started the car and disconnected the hose and there was no suction at first but after about maybe 4 minutes, suction sound came on very strong and loud, so do I buy a new canister purge valve ? I'm just a little confused because there was no suction until the car warmed up. BTW this is a 2008 Toyota corolla le.
@@nondainc . I'm thinking that even though it seems according to a few different tests I did on the purge valve that it does open and it closes if I turn off the car and restarted again but once I'm on the road driving up and down once the valve opens it could be that it gets stuck open and doesn't closed again until I turn off the car, I wish someone would explain if the valve is supposed to open and stay open while driving or is it supposed to open and close according to what the computer feels the car needs, because I'm suspicious that once it opens stays open and doesn't close until I'm done driving???
I got the code “GASCAP” on my odometer, then my check engine light came on and I got this code when I scanned it at the auto parts store. 2014 Chrysler 200 LX, do you think cleaning out the gas cap is most likely what I need to do?
2005 Lexus ES 330 I have the same codes I replaced the gas cap check engine light is still on ima drive 100 miles if it doesn’t go away then ima think it’s my evap canister 😅
I've replaced the gas cap with a new one, I've replaced the evap canister with a MOPAR new one. Still the P0441 comes up. I have to have the car inspected in July for emissions and register, what else can I do ? Haven't done the 'smoke' check yet. Hoses look ok. I know about the cycle of the mileage and it did the light after 225 miles there must be something else wrong. What can I do ?🙁
I've cleaned out the gas tank, I've replaced the gas cap and the purge valve solenoid about 3 times, I still get the code p0441. I am starting to believe that I can have a leak or it's the back purge valve. Help?
@@nondainc That’s not just an opinion. I’ve found several videos that say ESIM failure is extremely common in Chrysler vehicles. It’s also exactly what came up from the Autozone printout when my 2015 Chrysler 200 scanned and got the P0441 code.
@@nondainc I’m almost 100% sure my gas cap is good, and I already changed the purge solenoid. I’m going off of countless videos about Chrysler specifically since my check engine light came on literally the night before I was going to smog it and renew the registration. I’ve literally spent hours searching for causes of this code. What I’ve found is: 1. Gas cap 2. Evap purge solenoid 3. ESIM 4. ESIM canister (which seems to be a less common issue).
Ok I just got this code 3 days ago on my 2008 Toyota corolla le, car was running fine and suddenly as I got on the freeway and accelerated to get to speed 70mph the light came on, I got home and used my scanner and noticed this p0441 code I erased code and the following day as I drove it for 7 miles on stop and go traffic I got on the same freeway and check engine light came on again as I accelerated to 70mph, so I ran into your video and I knew my gas cap was perfectly fine, so I did this test on the canister purge valve, the car was parked so it was cold so I started the car and removed the hose to see if there was any suction and no, no suction at all but after a few accelerations t heard this noise and sure enough there was a lot of suction, so my question is, is it normal that when car is cold and you start the car that there's no suction at first and once car starts to warm up suction sound comes on very strong and loud, or does this test that I did confirms that purge canister valve is failing ? I'm just confused because there is no suction when I first start the car until it gets warm ? I love this car and I rather go to my local Toyota dealership and get the oem part.
@@nondainc. I already tested the purge valve and it seems to be working fine, but I don't know if is supposed to stay open all the time after the car gets warm up and you're driving several miles, I do food delivery with Uber eats so I drive for 6 straight hours stop and go traffic constantly turning car off and on and the car seems to be running fine, I haven't noticed any performance loss, I'm going to wait a couple of days to see if more codes come on, I already checked the rubber hoses and they're not cracked but I noticed the front part of the hose that connects to the valve and to the canister is totally dry and very stiff and the clamps are not doing anything I can remove the hose very easy and I do see the front part of the face of the hose little cracks, I'm thinking that could be the problem a small amount of air getting into the system because like I said I the clamps are not doing anything to make the hose tight and from my experience from a few old Toyota camrys I had in the past this little hoses are extremely tight and difficult to remove so that could be my problem. But because I don't have time to experiment I'm just going to take it to the mechanic to have it diagnosed so they can fix the real issue is probably going to cost me more 1000 dollars but buying another 2008 corolla would cost 10,000 dollars and there's no guarantee that it will actually run better than the one I have right now.
As you can see in the video we have uploaded, it shows there that we sprayed the WD-40 cleaner just on top of the tank and on the Gas Cap and dry it immediately with a dry cloth. It won't if you will spray just a small amount only on the right spot just to give it a good cleaning nothing will happen.
If you’re really concerned about the WD40, parts cleaner dries quickly and doesn’t leave residue. I wouldn’t use it on the gas cap, though, because it can dry out the gasket.

Is the fuel pump leaking? Did you do a smoke test to see if any of the lines are releasing the smoke?
This is such a great video! Very detailed. I have no idea in cars and I think my engine light went off after following this video! Thank you so much
Thank you for your feedback, Sullu!
One of the reason could also be the absorber (not only canister purge valve), which is a part of the EVAP system.
Hi Pavlo, thank you for sharing your opinion!
where's the absorber on a 2004 ? I didn't know about that being an issue.

What if you had the code p0455 replaced the purge valve sensor then 200 miles later now are getting the p0441 code?
The common issue is charcoal canister not cap or valve
If you don’t have a scanner how long till the light goes off?

Hi Benedick, since you are receiving multiple codes, we suggest getting your vehicle visually inspected by your local mechanic for further diagnosis.

Would the purge valve make your idle high and rumbling and could even shut off your car?
Hello, a stuck open/ not fully closed purge valve would cause a small vacuum leak that results to rough, poor acceleration or high idle.
