Dude, I'm two years late to this, but I had an evap leak. Couldn't trace it, tried smoke and everything. Change the purge valve and still had the issue. Lived with almost a year. Turns out, the purge valve I replaced the bad one with was defective.

Your videos are awesome! I'm a female who likes to do things by myself and work on my truck myself and I've learned so much from you and I've been able to fix my truck and get it to pass emissions thank you so much keep them coming cuz I'm still wanting to learn

Great vid. Some of the things you may consider are: 1. Set of cheap multi tester leads for applying power to a solenoid, just easier to control. 2. Q-tip 👍great for getting out the moisture great job. 3. Dielectric grease to lubricate the solenoid power connector, easy reseal. These are cheap and work miracles. Great job!

Hands down the best DIY mechanic on the net! Thanks!

Thanks for this video, I have the same truck model and year and following these steps fixed my problem. You also did a great job wording it out simple and clear down to the point...

Thank you for your videos. Thorough,Easy to understand . Spend the least amount of money. Keep living the dream.

Jam up video. I get these codes when it seems that the weather starts changing. I too changed the cap that I actually have a few extra laying around. I now have another thing to check out next time it throws that code, excellent video. 2002 Dodge Ram 1500 4.7 3rd gen. My truck is great just has the piddly little issues the 3rd gen seems to have. I can usually look in dodge forums and figure it out, but your vid was straight forward and helped me out greatly on this reaccuring issue. ✌️

Gotta be in Corpus with all that wind! Excellent to the point video brah. Thank you.

Firing off the parts cannon is not usually a good method, but I wouldn't say you fell victim to the gas cap. It is a cheap part, and I think it is worth it to try before digging deeper (time is money too). Also, on an older truck, the gas cap is probably towards the end of its life in regard to sealing. You did right trying the gas cap first, in my opinion. Another great video, ty

Wow great video bro I was having the same problem and I had no idea other than the gas cap. Thank you man

Great video! Going strong, get 500,000 on that truck!

Thanks for the video , well done & easy to follow

Like the vid. I got a 04 dodge about 5 months ago and I just got that code. Just a fyi bud. Ok I'm a industrial machinery maintenance mech. Tech 42+ years. I Work on a lot of cnc grinding machines that have coolant running on them.Water does not effect dc voltage as in shorting like on AC. You can put lines on your + - battery and stick both into a bucket of water and nothing will happen and you wont get shocked. That's why vehicles and machines like grinding machines control components that are exposed to the grinding coolant are dc voltage. Water is not a good conductor of electricity. Especially with DC. but Will cause corrosion after a period of time. Again just a fyi. But thanks for the vid I'm changing my canister not that much money.👍

Nicely done

Thanks brother gonna have to try it! I will let ya know!

Thanks for the info!

You are the man thanks 👍

Good job amigo 👍

More likely to be the nvldp natural vacuum leak detection pump. But the MOST likely is a cracked vent nipple on top of the fuel tank. The custom fix is a hinge roller pin to stabilize the broken nipple and covered with JB Weld, unless you buy a new fuel tank, if one even exists, $1200. Fuel tank from junkyard might work, but probably nipple is broke or about to break. The only real diag is to smoke the entire system and find the leak. For emission testing purposes you can fill the tank and clear the code and do a drive cycle. The evap code sensor is inoperative as long as the fuel tank is over approx 90% full. Also, on the federal IM test, you can have one module not ready to test as long as the mil isn't lit.

Very useful video! Thanks.

Thanks for your video, I got same problem.

The OLD GLAZIERS SAY GO LAY SOME PIPE. Inside joke. Great Videos brother.

I just had this exact same code. New gas cap installed but there was surface rust on the opening that wasn't making a tight connection, cleaned it replaced the cap no more codes. 😂😂

Thanks bro!

If it's not the purge valve try the charcoal canister above your fuel tank. If it rattles when removed it's bad.

Awesome

saved mesome money! Thank you!

got a Dodge Ram 2011 V-6, only 73,000 miles, so I got the P0456 Code, and I saw some videos, I decided that I would change the Evac Solenoid first, why? Because a lot of the videos have one thing in common, they changed out the Evac Pump first under the truck and the engine light came back on the dashboard. . I just took off the battery, and I un-screwed the bracket, and I took off the 2 hoses according to the videos that I had seen, and put the new one back on. I did buy a MOPAR Evac Solenoid because I really don't like to use after market parts, and its cheap about $35.00. Took about 15 minutes to put on, and answer the cell phone too. Been driving the truck now for about 3 days, so far No Engine Light, and if it does come on, then I will get under the truck to change the Evac Pump. No big deal. Was it necessary to take out the battery? For me, it was easier that way, gave me more room to work with. Take your time, be patient and you will be OK. Thank You.

You got lucky with a little moisture mine wasnt that issue

Bro, I had the same code on my 2011 ram 1500 5.7 hemi. Went to the smog check with the check engine light on. Didn't pass. Went home, disconnected the battery to erase the codes. Went back a week later. No check engine light, passed smog check. Didn't have to replace a thing.

Same truck. I changed the leak detection pump and the engine light went off a month and today it came back on same code msising gas cap / small leak. Should i mess with it again or try this purge part first?

What did you end up doing to fix it? Mine just started doing this a few months ago. I clear the code and it stays off for about a month then comes back on. So I’m guessing not a fluke anymore.

Are those seat covers? Very nice! Where can I get a set?

Where do your lines hook up too I know one of them goes to the throttle body but where does the other line go to?

My truck 2005 dodge ram 15000 5.7 hemi threw 3 codes, P0440, P0113, P0441....I removed the filter and washed it with a high-pressure hose and allowed it to dry in the sun for a good 2 hours. I reconnected filter and all 3 codes disappeared. However, after 4 days without the check engine light being on, I performed a self-diagnostic and code P0585 showed, but the check engine light is not on. Shit is weird and frustrating. I love this damn truck and put a shit ton of money in it. Bro, your 2003 is close to 400K miles. Have you had to replace any major mechanicals? That mileage is very impressive. I currently have 136k. Had to replace transmission once (go figure) catalytic converters, all 4 o2 sensors, water pump, valve covers, etc...

You might have a leak in the purge valve. Why not blow threw it to see if it is slightly open?

I have a 2004 dodge ram 1500 5.7 hemi , did your truck spit and putter? mine has 3 that say evap leak (very small), evap leak (small), and evaporative emission system, it doesn't spit and putter after half tank but if it goes a little below half it does that, was wondering if this is just a normal problem for these year rams? was thinking of taking it to a shop and having a smoke test done but don't know if I should just replace that part first and then go from there.

Dam bro sick 390K miles! Did u end up buying a new one cel come back? What’s the secret for having that much mileage? I just hit 211k miles on my Jeep GC! New sub!

Was wondering if that would cause severe blowback coming out of oil fill cap? I'm getting ready to cut my catalytic converter off cause I had caught fir a couple times

What’s the part # for the hose’s?? Mine is broken and I can not find it at all

So does anyone have a part number or link to the hoses that come off the vapor canister

I had the same code on my 2017 got a new gas cap and the check engine light went off Replace the gasket first and replace that part

Is that ohm reading for other years. I have an 07 that reads 15.5

Is it safe to drive if that code is showing until it gets taken to a mechanic?

Did you have bad fuel economy before u replaced it?

loose gas cap will cause that code too.

What happened I'm having the same problem? Did it come back on?

Bro you know you can turn your key on and off 3 times to get codes without a scanner don't you?? the truck is it's own diagnostic tool for reading DTC's!

The click test is not 100% accurate at all once its in the car it could be intermittent

I got 36.4

Bro go to the dealership for your parts please.....Those Aftermarket Autozone / Oreilly/ Napa/ Rock Auto all Garbage China parts that arnt worth the cardboard they are shipped in.

I got 36.4
