He's competent and a nice guy. I met him in Chicago as he was staying at the Fairmont Hotel, as I was, for the first Automechanika. Sadly, however, I go to sleep when I watch his videos.

He who can turn madness into a method should be well celebrated. Best of all is showing methods of trouble shooting; the starting points or what to tackle first and how to work one's way through the complex technology that has become the modern automobile. Great stuff.

[@knobrush]

My father's 2003 Town & country had the same codes. I did a quick visual inspection and found the hoses attached to the purge solenoid were brittle/cracked. I also checked the gas cap and the o-ring on the cap was brittle too. $2 worth of vacuum hose and an $18 gas cap fixed it.

[@edgerrr]

Checking the easy thing first paid off for me and my 2015 Dodge Charger (with the mid 5.7) where I could tell the purge valve was open by simply using my finger (while the engine was running of course). Banged the valve on the manifold a few times thinking the solenoid assembly might be stuck, sprayed a tiny bit of WD-40 in there and when I started the engine again, no vacuum! Keep up the good work Eric and Co.

[@steverandall5814]

Another clearly explained diagnostic video. You have a gift for simplifying the complicated so anyone can understand it. Thanks for doing these videos...keep 'em coming!

[@SoCalSlaughter]

Love all your videos. Been binge watching all of them. I enjoy more the diagnostic side instead of just parts changing or How-to just change parts. I own 5 vehicles, so Im always working on them on the weekends. Watching your stuff has shown me new ways of finding problems. Example, I have a 90' Suburban and its had a O2 sensor code on and off for years. Before I'd just change the sensors out. But this time I broke out the ohm meter and found the ground was pulling 1.7ohm at the ECM and causing the light to trip. I fixed the ground, now reading .2 and the light has been back. Thanks for all the great content!!

[@georgecolbert3247]

You're right. Unplugged the purge valve wire on the 05 Ram hemi and turned the connector so just the engine vac was connected. Checked it and it's pulling some vacuum right through the valve. The service manual says it vibrates 5 times a sec, so it makes sense that the seal inside is bad. Great video, thanks, that saved a lot of time!

[@RangleRiot]

Thanks for putting this together...solved my issue on an '08 Caliber. Total cost: $11.00 from junkyard.

[@adamtrombino106]

I had a Caravan come in last week with the same codes. Previous shop put in an ldp, replaced most of the rubber hoses, fuel cap and neck, and were looking at the tank or canister next. Total parts cannon. And just as you showed, the purge valve was the problem. It took time but it would intermittently internally leak vac when commanded off. To the shop's credit, they did smoke it and found nothing. I used a simple Mighty Vac with a gauge on the output port, and sometimes after about 5 mins the purge would start to leak down. Sometimes it wouldn't. It seemed to depend on how much vac I applied. 14-16 it would hold all day ( ok, I exaggerate, but for an hr) but above that it couldn't. IMO I would not use aftermarket purge valves on these systems. They just don't last. Buy the Chrysler OEM.

[@livalittle100]

Thank you for making these videos. Most of us like all the kinds of videos you make, circuit diag to engine swaps, We love it all!

[@stu110213]

Hey Eric! Keep up the great work love your videos!

[@stevenrice47]

I'm a moper man. I've owned 17 Chrysler in my lifetime with 9 currently owned between my dad an I. Every modern Mopar I ever owned have had an issue with the purge valve. The issue with them is cheaply design solenoid will bind in the housing due to gunk build up. They can be cleaned with brake cleaner but that will only last for a few weeks. Since the valve is just $25 bucks pop, it's best to just replace it with a better designed aftermarket unit.

[@LynxStarAuto]

The aftermarket ones are even bigger junk! And if you have a Gen 3 system in a Chrysler, aftermarket purge valves don't even work properly on those systems out of the box. You need to go OEM, or it will continue to set ghost codes and drive you insane.

[@jamesterrill1938]

Thank you for posting that link and for your vid. Even though my vehicle isn’t a van but I’ve been plagued with the EVAP codes for a while. Hard to really see sometimes what’s happening without a good scan tool. Thanks again for this “quick tip”. I’ll give it a try on the Jeep from Hell at the beginning of the week.

[@nismo2070]

Great video! I used to inspect cars in upstate NY(Plattsburgh) ten years ago and evap failures were a big problem. Especially with all the salt on the roads up there. Of course I could get most of them to pass by clearing the code/codes and running it with a full tank of gas. It would run every monitor except the evap, but would still pass ;)

[@SouthMainAuto]

The only problem with that is you don't fix the car and make zero dollars on a repair and the engine light remains on.... It is similar to people who delete diesels. They only do it because it is easy and they have no idea how to fix them. Don't you think it would be more beneficial to your shop and your customers to just fix the cars the right way?

[@KCautodoctor]

​@@SouthMainAuto @nismo2070 had to move to a state (Oklahoma) where there is absolutely no vehicle safety or emission inspections, since he could not make a living in NY State giving away "repairs" for 1/10th of what it would cost the customer to fix correctly.

[@nismo2070]

@@SouthMainAuto Absolutely! I did that as a last resort for good customers that were strapped for cash. We did end up repairing it properly, just after they got the sticker. Yes, I know it's cheating, but some people just can't afford the repair for months.

[@nismo2070]

@@KCautodoctor I didn't "have" to move anywhere. The cost of living was getting out of hand in NY. My income DOUBLED by doing that and the cost of living is very low here.

@@nismo2070 amazing what happens when you properly charge a customer for the correct repair and not try to "patch it" just so they can get their legally required emissions inspection sticker. You are the one that was bragging about getting around doing a proper repair.

I got these two codes on a 2002 Caravan, come to find out, there was a technical service bulletin on this Leak Detection Pump (along with code p0456). Thank you for the video because parts of these bulletins are not for the average person.

[@pyro323]

I used to work at a ski resort and my boss at the time overfilled his Chevy 2500 and since then it wouldn't take only a few pennies worth of fuel. What happened when he over filled his gas tank was the fuel ended up flowing into an evap solenoid (on the back of the gas tank) and blocking it from opening so air couldn't escape when filling the tank. Once the solenoid was replaced he could fill up his tank again.

[@BoerGuy]

Clear, concise, well explained. Just WOW!

[@jdtractorman7445]

Sometimes when purge solenoids go bad it causes an extended crank time after fueling the car with gas because the fuel vapors go into the intake and create an overly rich condition.

[@Blazer02LS]

That happens when they stick wide open, usually. In this case it's more like a tiny leak in the valve.

south main auto.so was it the purge control valve?????

[@williegillie5712]

Add the TIPM to the equation and you got yourself a mighty fine vehicle to drive.

[@jakeaustin9894]

Don't forget Chrysler's infamous bad grounds and poorly located PCMs.

[@ProductsOfMorticians]

Well, South Main, you failed to mention what you/you tell your customer to do after the new purge valve is installed. The customer may still see an engine light on or may be detected when going to get his inspection sticker (which failed because of the valve/0456 error). What's next to do? What do you tell your customer to do to be able to get the sticker??

[@tdhodroid]

Keep the tips coming!

[@vlstyles]

Definitely on GMs..Gross leak check the Purge Solenoid. The pintle does not move even though the coil in the solenoid is "good" (there is voltage drop), so the PCM assumes there is a leak because no fumes are drawn into the intake (no vacuum present)

[@Discretesignals]

Some GM models had a purge flow sensor that would detect if there was no purge flow when the purge solenoid was commanded opened. The most important thing is to know the system your troubleshooting. One of the hardest for me is Toyota/Lexus evap systems.

[@jeffreymurdock8366]

Another common problem on dodge/Chrysler Van's is a evap canister leak code. Those hoses going to the evap canister are held in place by plastic clamps that dry out and become brittle and in the end fail causing a small leak. Cant tell you how many of those I've fixed. I started carrying packs of clamps in assorted sizes just for that reason.

When you used the vacuum gauge, you unhooked the bottom hose and placed the vacuum gauge there? Sorry if its a stupid question?

So In this scenario under mode 6 test it would pass the engine running test but fail the key off test..am I correct In this thinking. Thank you for taking the time to explain knowing how exactly the system operates makes it so much easier to understand.

Hello Eric, I've been plagued with this po456 for a while now on my 2006 chrysler T&C. Found a broken hose clamp on the charcoal canister. Light went out only to come back on months later .Smoked it and can't find nothing but when I fill this 2006 Chrysler T&C up I got gas leaking out the top of the gas tank sending unit . Could this be where the small evap leak is and if it is why don't I see any smoke coming from there? Hope you or anybody else answers.

I have a 2006 Town & country I had a PO455 code, but the day before the code came on I smelled gas fumes through the AC vents. could smell the fumes when I opened the hood so I tested the purge valve with the vacuum gauge it worked but it did not open all the way with very little vacuum, I hit it with a rubber mallet it opened all the way, put on a new one problem solved.

Hi, Eric. I don't know if you reply to viewers or not, but here I go. I have a turbo civic 2018 with 21k miles that sat for a year due to me being overseas. A week after I started driving it, I noticed both p0455 and p0456. I tested the purge solenoid in the engine bay, and that's fine. My next guess is the canister vent valve. The gas tank is capless, so i lubed it well in case the seal wasn't closing. Can you help me out?
