Hemi Ram 2500 & The Dreaded Check The Fuel Cap Light

[@clintprice2123]

Eric, your ability to get to the root cause of electrical issues is second to none. You’re too humble to admit it so I’ll state it for you. If only there were Eric O’s all over, the public wouldn’t be firing the expensive parts cannon often.

[@johnlarkin549]

Theres only one way to become so great! Knowledge passed on from a parent(in Eric’s case or a good teacher and a good memory . But your 100% correct Clint 👍 have a beat dayand don’t forget to leave your comment! Oh you already have I’m replying 🤣🤣🇦🇺

To help others, I had this issue with my 2012 Ram Power Wagon. It drove me nuts because I really need my remote start to work. I replaced the gas cap (no luck) and I replaced the Evap Canister (no luck). The check engine light would pop back on within a couple minutes every time. Turns out that if I give it the recommended amount of clicks on my gas cap, the check engine light will come on, but if I only click it only once or twice it will not come on. My issue has been fixed for a few thousand miles now by only clicking the gas cap twice each time I fill up. I'm not sure why it works but it definitely works. I found this out accidently, I haven't found any other people with the same experience. Give it a try before pouring money into it.

[@teacfan1080]

I had the lovely P0456 (very small leak) code about a year ago. Gas cap was on. Decided the most common fix was a new gas cap. Sure enough, that fixed it. The seal on my old cap was just simply shot. Finally a cheap repair, only $10!

[@richardpayne7851]

I put a plastic bag over my gas cap to test the cap and then screwed it in to the tank, light went away almost immediately. Of course that was after I had replaced the purge valve and ESOM. But it is a good quick test for the cap.

[@delano62]

Gonna give that a try next time my Ram throws the code. Good idea.

[@wallingj68]

I was thinking Pa's and thought Pennsylvania, but then I thought of how they drive, and then I thought of other body parts, and then I thought, I don't think I want my lips anywhere near that, so I ended up grossing myself out and just watching the video's. Please don't burn out to keep the YT overlords happy. If you need to have extra support somewhere else, please let us know.

[@Stover1928]

For a guy who stated at the begining of the video that you don't work on many of that type Chrysler product you sure know your stuff AND can splain it in language that makes sense. Looking forward to part 2. Thanks for teaching!

[@johnsamuelson3234]

Eric O is on fire with the videos!!

[@DistinctOgre]

You always say if I can do it, you can do it, but we don't have the data you have. Computer data, and even more importantly experience data. Keep doing what you do man. You've taught me a lot.

[@jeremyscott2243]

Just a heads up, on chrylers with the wiitech you can go under misc. functions and do a small evap leak test. It's an automated test that's helpful to point you in the proper direction.

[@williamgagnonroadboxservice]

See you in part 2 And Thank You for showing and explaining the system

[@curtgomes]

I got a purge code on my old Toyota truck. I am a DIY shade tree mechanic, at best, and not really familiar with technical issues around these evap systems. After reading a little, I found it was suggested that the gas cap might cause my issues. A new gas cap from Toyota was pricey and I wasn't sure it was even the issue. I bought a cheapo $5 Stant universal replacement. I removed the rubber gasket from the Stand and replaced the cracked one on my OEM (27Yrs old) gas cap with that. Problem cured. How lucky can you get? Eric, thank you so much for these great videos...

[@edchenal821]

Your patience always seems to pay off. Good video.

[@NskLabs]

8:55 Small tip if I may, I use a plastic syringe for similar tasks. Put a rubber or some plastic cone on it and use as a pressure/vacuum source for testing, plus it is useful for small liquid removal and water lines decongestion tool.

[@DiversifiedMachinist]

Yes, I will wait on the follow-up. I have an '05 2500 PW with a similar problem. I'm sure it's a leak as it only happens when the fuel tank is low. I'll wait and see what you find before I continue. Thank you for this

[@funnypranker34]

Oh boy, I replaced the same thing on a 07 dodge charger that had the same gas cap code and that actually fixed the issue

I recently started at dealership but they don’t have me doing electrical diagnostics yet I’ve been there a couple weeks and they have me doing mostly nuts and bolts stuff I guess they are working me up to it

[@spelunkerd]

These systems always seem to be a little more complex than I expect. I wish service data was a little more explicit regarding how each of the valves work. Even the pressure of a smoke machine can close valves that you may expect to be open.

[@SouthMainAuto]

In all fairness Chrysler OE info on the ESIM system is pretty good and very detailed. I have a "brief" understanding of how it works with out the need to go back and read the nitty gritty details so I hope some of my ignorance doesn't make you think they don't have a detailed explanation. Just for me, sometimes during the diag certain details are not needed. If I was digging deep and not satisfied with my findings, it would be at that point I would jump into service data to find what I needed. Does that make sense?

[@uenragedbro]

@@SouthMainAuto did that change as you got more experienced?

[@noelcastle3986]

Great to the point explaination your a great teacher . Interesting to see the outcome of part 2 .. The switch may have been leaking the fuel vapours near the plug receptacle causing the crusty connection.

[@toddw.9845]

The fuel tank pressure sensor is used to set purge system codes and the esim is used for leak detection.

[@The98deville]

IMO the top 3 car guys are Eric O, Pine Hollow Auto Diagnostics and Rainman Ray

[@SedatedByLife]

What always bugs me with manufacturers who use a gas cap for a light when typically it isn't a gas cap problem. Usually an evap problem from the fill neck down. When I worked at a Chrysler dealer, most of the time it ended up being a rusted out hose clamp causing vacuum leak or just rust that finally ate through a steel component to the tank or a purge issue that the ecm didn't catch. The gas cap was usually the last thing we encountered as the culprit. It makes a customer spend the money on stuff they didn't need before getting to the actual problem

[@DeweyCheatumNHoweLLC]

Ooh, a cliffhanger, like in the Perils of Pauline!

[@oh8wingman]

Pa stands for the metric pressure system using Pascales. 1 Pascal is equal to 0.000145038 PSI. For a quick conversion to PSI divide the Pascales by value by 6895. 73/6895 = .0106 PSI.

[@ronwade2206]

I "had" a two year old, 2014, Chrysler 200, it had the same light on. Only the expensive Chrysler gas cap would turn off the light. That was the first of several, simple items where parts cost way more than they should have. Did I mention I had it with this car? So, this will be my last Chrysler product, ever!

[@brianhume4743]

Nothing worse when the doctor says I'll have to back probe ya!

[@waiting4aliens]

I have a ram.The company attitude seems to be "Well that barely qualifies, how can we slice a few more cents off of it." They are OK as occasional use vehicles after they are seven years old, but may the gods show you kindness even if you have a technical background if your living depends on them.

[@bugdog9]

Awesome...move to Tampa bay..we need you you here...

[@murphymmc]

Eric, nice work. Your brain follows the pathways which few of us see as clearly, if at all. Your explanation of the systems makes perfect sense, until someone like me takes off on that trail. Then you get the perfect picture of "a cow lookin' at a new gate", that would be me, temporarily.😂

[@PMELKUS]

This is the same problem I'm having with 2013 Dodge Ram. Frist, thing I check was the gas cap which look good, I clean the 0-ring and put a bit of lub on it, clear the code but light came back on. Thinking no more than it cost I would just replace the cap with a new OME one but no joy. As of this post I have replace both the Purge valve and the ESIM with OEM parts but so far no help. If I live up there where Eric dose I would just let him have it.😉

at school ..we had a teacher who spoke quieter than the others ... when asked why .... " so you have to pay proper attention "

[@mistermr2147]

Pa is Pascal, it's the SI unit for pressure ( like how Kilogram is for mass, Kelvin is for temperature, etc.) I don't know why Pressure has so many different possible units (Pa, atm, Torr, mmHg, psi, bar, etc.) But it gets pretty damn annoying. Hope this helps.

[@jeffryblackmon4846]

Not to mention trying to convert from one unit to another!

[@scottmccambley764]

Replace the short right angled hose on the evap pump valve or try to put screwclamps on both ends of the hose to seal it better. From experience it is seldom the gas cap, or the evap valve itself. But that hose is exposed to all elements under the truck.

[@robertrpenny]

EO, 1 Pa is 1 Newton force per square meter in the SI system of metric units. 1 psi is 6895 Pa , so it's a very small pressure

Pa is a Pascal, SI unit of pressure. 1000 of them is one Kpa, and just under 7000 of them is 1 psi

[@falloutguy8878]

Cheers dude for the great video? Your funny Mr O love watching your videos you make me laugh with your funny ways and saying.keep safe dude 🙂

[@notrut]

That rear body conversion provided a hint from the start?

[@lancecorey6582]

Pa stands for Pascals. 1 atmosphere is 101300 Pa. The weather channel would report this as 101.3 KPa.

[@huzudra]

I have seen so many intermittent failures on the Chrysler ESIM system, it's very frustrating. Usually the little weighted plunger getting a little stuck sometimes or just not riding smoothly enough or the contacts for the switch failing to operate properly or the connector on the ESIM failing due to corrosion intrusion along the sealed seam of the plastic halves. Thankfully most of the time the ESIM is in stock at the dealer, it's not terrible expensive, and it's easy to change so if the customer wants to parts cannon it the risk is fairly low.

Pa is pascals. It like bars. It measures the pressure of a gas.
