The shake test is not how you determine if this module is faulty. You test it for an open/closed circuit. It should be "open" with no vacuum or pressure present. With the module disconnected from the vehicle and in the upright position, connect your multi-meter probes to the two pins in the connector. Set your meter to Resistance w/sound and cause a vacuum on the small tube and then a pressure on the large port using your mouth with light pressure. You should hear the internal parts move when you have enough pressure and vacuum. If your meter doesn't beep for both then the module is bad.

So true I bought three mopar and all rattled hahaha

[@jakegrock3827]

I love how there was no unneeded bullshit. You stayed to the point and didn't ramble on about some stupid irrelevant shit. Good job.

This was the quickest fix I’ve done on my truck. This video was great straight to the point and showed visuals!

You are very good at how you present the information and troubleshooting. I enjoyed the humor, but more the visual guide, and even how to remove the items.

[@timkuhn-bv1pr]

Bought two of these from local NAPA store and one from Amazon…both from NAPA rattled when I took them out of the box. Amazon delivered a none rattler and just installed. Replaced fuel cap also. Light remains on…hoping it goes off tomorrow. Thanks for the info.

[@JakeLewis02]

Any luck? I did the same thing. Check engine light turned off, gas cap light stayed on. Today check engine light is back on.

[@dougeisenhard6816]

My Napa one also rattled. Did the code light eventually turn off

[@WeThePissedOffPeople]

The one i got from auto zone rattled as well and a month later my gas cap and check engine light popped back on.. ordered a new 1 so hopefully it doesnt sound like a baby rattle..

[@Mark-sw8kp]

I've got the same problem I put two on also any new ideas yet?

[@pzpinkslip123]

Does the check engine light cause a sort of limp mode? I just replaced my gas cap this is next. Truck is definitely running lean. Maybe the engine light or maybe caused by the leak. Either way thanks for video.

[@busta981]

How long does it take the code to clear? I have this issue and the duralast part seems to rattle. Confirmed this with a different autozone that had the same part.

[@user-vr3dm5rs2v]

I have a 13 ram 1500. Replaced fuel cap and evap valve, light still comes on. Upgraded my fuep tank to a 32 gal now because it was pumping at the gas stations. New fuel tank solved the fuel pump issue but gas cap light continues to come on. Possible charcoal canister?

[@geoffboyd]

What does this issue cause the truck to do improperly? I understand how to fix it but is the only issue the light on the dash or will it effect performance, gas mileage, or gas leaks?

[@drake3362]

I did shake test on new on and it rattled did I get a faulty one?

[@ToyStoogesVending]

I have a 2017 dodge ram truck. gas cap light on and after driving it when parking it i smell fuel so this is the problem?

[@markpolakovich6697]

I replaced mine and still get that same annoying light on my 2014, it seems like it does it when the full tank gets to around 3/4 full….suggestions ?

[@jammalmurrell8991]

My set up is different I have a 2015 lamarie 1500 my gas cap light on and I watch few videos and my under truck is different from the trucks I seen on KZbin videos

[@brentblackburn263]

I got the p0456 code on my truck and when I give it gas I hear a whistling noise any thoughts on that?

[@richardcardenas4876]

Good afternoon, I hope you can help me with this issue, I got the same message and code and I replaced the Evap Valve, lights went out but after a few weeks the engine light came again with code P0455, I was wondering if you have replace the purge valve or something else to fix this code, thank you in advance

[@miltfreberg9582]

After changing the valve and clearing the codes out, I still had to disconnect the ground from the battery for about 5 minutes before the light went off

[@SethTheSpeaker]

Replaced cap (with a dodge manufacturer) and evap valve. Check engine light and cap light still on. How long did it take for everything to reset?

[@danielserrano9443]

Try to do what he demonstrates in this video, or get a obd-2 scanner autel brand is good you can get a used one.

[@amazingrazin]

FIxed mine by unhooking the battery and hooking it back up.

[@cappyjpadgett]

Is that towards the front or rear of truck?

[@z31freakify]

Just bought 2 new ones and both rattle, only difference is the old one has a sound like broken stuff when holding the plunger inside. The new ones rattle as well but when holding the plunger there's no broken sound. Are the new ones supposed to rattle as well?

Did what you said, but the new one rattles! There is a cylinder that slides back and forth so not sure if the old one was actually bad.

[@Robert-vv9yg]

Mine did rattle as well, the new one. But I replaced it and it fixed the check engine light. I wonder if the oring was leaking. the old oring was flat. looked more like a flat washer..I might check the old one with the new oring just to see if that was the problem.

What if you change this part and the light is still on, even after disconnecting the battery for 10 mnts?

I changed my gas cap and the leak detection valve and my light is still on it’s been 2 days could you help me cause I don’t want to keep throwing parts at it also was I supposed to grease the o ring that can with the valve?

I'm having the same thing. I changed the can now the cap light is on truck won't start when it does it idles terrible

Check those tubes, a squirrel chewed a hole in mine right over the fuel tank!

I have purchased two of these and they were rattling brand new out of the box. installed one anyway and my gas cap error was gone, but just for a short while and the error message is now back. I wished this would have worked.

[@bamaman6959]

I had the same thing but I change the gas cap first and the light went off so I did not buy the other part

Same here. Not sure what the fix is and I need it now cuz I have to pass emissions in 2 days. So fing stressed over this small but huge problem

[@bigdaddyshouse]

Hey William, the system runs checks periodically and it will eventually go off once it sees that it's working. For my fuel cap light, I think it took two to three days before it shut off and it took about 2 weeks for my engine light to shut off. hope this helps Thanks for watching brother
