RAM TRUCK GAS CAP LOOSE HOW TO FIX ERROR P0456 or P0457

[@troyperezsr]

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.

[@chadjohnson7544]

So true I bought three mopar and all rattled hahaha

[@Bay_Acres]

So, my new part rattles. I haven't installed it yet because of that. I'm leary because of this video, saying it is bad of it rattles. Am I good to install??

[@fredkeele6578]

Well, I just bought one and yeah, the rattle crap is misleading. I bought because I've already changed the gas cap, and vapor solenoid, so hopefully this takes care of it.

What was the part called

[@Chepo713]

I bought mines but its still came on the gas cap on the dashboard

[@juanasn4758]

​@Chepo713 replace gas cap too. Then reset the computer. Unplug negative terminal from battery. After start the truck lights were erased for me.

[@chrisroday7128]

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.

[@mindeelediehl3590]

Thanks for this very simple and informative video - seems to be the exact fix I needed. I have an 07 Ram 1500. Filled my tank up yesterday and immediately had “gas cap” show up on my dash, then on my way back home (

[@vdrewerdv]

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

Took me longer to crawl under the truck than to take it off and shake it lol. Thank you so much for this video.

[@kevinmccliment7591]

I replaced mine per the video. For the hell of it I shook the old one and yes it rattled. I had to disconnect negative on battery to reset gas gap warning light. Thanks man $25 fix.

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.

[@chrishansen4731]

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.

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?

Just had it replaced and my gas cap is still on will it go off bye itself?

[@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
