Kool info to know your video is educational since the dealer missed that they probably Dident put it on a lift

[@hestheMaster]

If you have a similar problem go to a shop that will perform a smoke test. They put a connector that matches your gas cap and fill the system with smoke. Believe me you will see where the littlest leak is! Ofcourse you should visually check for obvious things first as the smoke test is a final and possibly costly resort

[@thewiz8073]

The problem may not go away instantly after repair because the computer will need time to decide that there us no longer a problem. The way around it is to disconnect the battery for 20 mins and then reconnect. If the problem is truly gone the light won't come back on. Do you know if it's had to to reset, or if they disconnected the battery. Just a thought.

[@autobotavengerfireballxl5339]

Lucky yours was in an easy spot my leak was on top of the tank

[@JustbeingSheShe]

My 2007 is doing this. We have inspections here in my city and I failed because of it. I changed the gas cap and it still came back on. I'm going to look underneath it in the am to see if that cord is unhooked (hopefully the 2007-2017 model is slightly the same under there). One dealership "fixed" the problem and the light came back on so then I took it to Dodge and they said I need a new tank because of the line going to the tank. They said they can't repair the line because the tank and the line is one solid piece, but get this,,,,, that's what the dealership before them worked on. Idk who's lying so I'm trying to figure it out for myself. Thanks for this info.

Definately get another opinion from an independent mechanic. Or maybe even utilize justanswers (I am not affiliated with them in any way) but I have used them on multiple occasions for times like this and they have helped me out and saved me money.

2011 ram 1500, I bought the new gas cap, also a emissions thingy, ,Ram gas cap alway had an issue with refueling, like the filler neck wanted to pull away fro the truck, I guess that wore down the clip so it wouldn;t lock the line together, I would get under the truck hook it back together, and disconnect the battery for a few hours, and the code was gone,finally decided to replace the line it self, 15 bucks at the dealer, little clip is prob 50 cents, but the upper portion of line is where they get you...It' called the fuel vapor recirculation line, or as I call it bullshit California smog control...

After replacing all those items did you disconnect the battery for 20 mins to reset the light. I've heard others say that the light wouldnt reset on it's own after repairs, but after a 20 minute disconnect it didnt come back on. It's worth a shot.

Great video! So I have a 2016 ram 1500 with a po456 code. When I go to start it there is a very high rev then idles down with no fuel smell So I scanned the code with a small scanner from autozone that suggest the canister purge valve im not sure how accurate this is. Before changing it what are the chances that it is the leak detection pump?

[@thewiz8073]

It's possible I suppose. It does sound like more of an actual vac leak. Have you check your vac lines? I suppose a bad gas cap could cause this issue as well especially if you are noticing the issue mostly after filling up.

Do you have to clear the code for the gas cap light to go off? or will it go off on its own?

[@thewiz8073]

If you disconnect the negative battery cable for 20 minutes it should clear the code. If the code comes back after roughly 50 to 100 miles of driving then that wasn't the issue. If you don't clear the code it will just take time for the computer to realize the issue is no longer and should clear on its own.

Hey sorry for the delay, I've had some health issues. I did not have any of those issues with my truck. If you havent already, I'd check other simple things like fuel filter, air filter being clogged, fouled plugs, or possibly a failing fuel pump.

[@hestheMaster]

A leak detector pump that fails in the closed position will cause this. Check it out first before getting a new fuel pump.

Ram 2014 5.7 1500 gas cap light came on this a.m. really hoping its that little clip...cause im not sure where that white sensor is that you showed at the beginning....and whats the worstcase scenario for driving like this today or next few days with the light on..?

[@thewiz8073]

The leak detection pump, also known as the EVAP system integrity module (ESIM) is generally located at the rear of the fuel tank on top of the tank. Not sure if this is the correct model for your year but it will look similar to this. www.summitracing.com/parts/MOP-04861962AB. Is it OK to drive? If this is all it is then yes it's probably fine, but I can't really make that determination for you. You can go to Autozone and have them pull the code that is causing the error and then you'll have a better idea of what the actual problem is. But, being a RAM and the gas cap light, it's likely that it's one or the other. Hope this helps.

Both very simple if you are mechanically inclined. It is advised to always disconnect the negative side of the battery cable prior to doing work on the fuel system and always wear standard protective gear.
