I have seen too many videos from others that are either too long because they dwell on useless information or others that are too vague and don't offer enough information.

I thought your video was very educational, to the point and covered everything in a short amount of time. This is an excellent video, IMO. Congratulations and thanks for what I consider to be an excellent presentation. Also, I use a laser pointer and it has enabled me to find leaks that I may not have seen without it.

Great info, thanks. Maybe someone can answer this. My understanding is the entire purpose of the EVAP system is to prevent gas fumes from going into the open air, ie outside the tank. And in fact those fumes are trapped and drawn back into the engine through the purge solenoid, and burned like fuel. Which was the first thing referenced in the video. So why is the vent solenoid in the Open position? Thanks.

[@Badwolf6466]

Good job. I refill my machine with baby oil. A lot cheaper and smells good. Another thing is I bought a smoke machine for smoking intakes for vacuum leaks. Much cheaper than a evap smoke machine. You just have to add a inline check valve so gas fumes cant back flo into the machine. And test the check valve before each use.

[@blastforyou]

Hello Mike,I have a 2010 F150 4.6 that has error code 466 and 455 and when I checked the Evap vent solenoid by applying voltage from separate battery source it functioned normally. When I checked for reference voltage at connector with key on engine off i had 0 volts.I checked the purge solenoid connector and had 12 .15 KOEO. Both of these sensors should have 12.15 volts from parallel connection (same green wire color)when key is on and PCM controls switching thru ground side. This failure of canister vent would also explain the 455 (gross leak) code wouldn't it. I am right to just focus now on looking for break in circuit. Thanks for great video.

[@ChevySS1968]

Thanks for the vid! I'm confused about the vent solenoid. Why is the vent solenoid 'open' with engine off? Do you mean it's open to the air? That would defeat the whole purpose of the EVAP system, lol. Or is it simply open to the EVAP system? And if it is open to the system, wouldn't you want it that way for the test?? I've got my new smoke machine coming tomorrow (8/29/2022), so I want to do this right. This dang P0442 code is driving me nuts!

[@GoTechTraining]

Hello, The vent solenoid is open unless the vehicle is testing the system for leaks. This is because the fuel tank needs to vent with the expanding and contracting associated with temperature change. This ok be cause all the venting must first go through the charcoal canister to be scrubbed before entering the atmosphere. The system checks for leaks because if there was a leak, hydrocarbons would be able to vent from the tank without first going through the canister. To smoke test the system you must first close or block the vent solenoid off. I hope this helps and good luck finding you leak. Ryan Wilsing, Technical Instructor

Dirty or clogged canister? Should I just clean it out? Clean the sponge/fet etc? What will help my low/rough idle? That’s what I’m trying to fix. I’ve seen that if the purge solenoid on the canister doesn’t close to cause combustion, it will cause a low, rough idle 🤷‍♂️ It only needs to go up 500-1000 rpm to be completely smooth. It’s idling just around just around 1050 instead of 1200/1300 (1250 is my target) 🤷‍♂️ Tia.

GREAT VIDEO!!! The hardest part I find using a smoke tester is closing the system. I don't own a snap-on Solus... That is yet.. So my daughters car has the P0456 and P0457. Ride is a 12 model Avenger with the 4 banger engine. Moving past the typical cap I've checked the following. 10" of vacuum holds indefinitely on the purge solenoid. When applying 12vdc on and off she opens and closes and holds vacuum as it should. Next, I visually checked the seals inside of the evaporative pump. Nothing out of the ordinary? Reassembled everything. My smoker is mineral oil based and has been my go to tool for engine sealing and is very effective. My question is how can I close the system on a 2012 Avenger to accurately perform the smoke test?

I have a 2005 Honda Pilot that doesn't pass the EVAP self test. Using a Launch Scan tool. But I'm not getting any EVAP codes. My FTP reading when the engine is off is a -0.10 hg. Once the vehicle runs and I monitor it, the pressure goes up to about 0.29hg. The only code I have is for a p0172. Is it common for EVAP issues to.make an engine run rich? I've ruled out bad 02 Sensors (replaced already) and Injectors. Thanks for any input. My Temp reading at ECT 1 is at 183-185 F. Should be at 195. I did get an intermittent p0116. I will be replacing my thermostat since it's inexpensive. I don't know if that's also contributing to my issue.

I've replaced that exact purge valve solenoid for 2016 traverse twice now. Same result for both times, engine light will stay off for a few weeks and then throw the p0496 code again. Any ideas/recommendations? I haven't replaced gas cap yet, guess that would be the next cheapest. However, what would cause a new purge valve solenoid to work like it should for a few weeks and then get stuck open?

Need some guidance here, I did a smoke test for vacuum leaks on my Ford and one of the places smoke was coming from was the vent holes on the bottom of the diaphragm part of the egr. The smoke isn’t coming through the little vacuum line though, because that still holds vacuum and opens and closes the egr properly. The smoke is coming through the intake side of the egr. Further investigation showed that I could suck a decent amount of air through the egr even when it was closed. Anyone know if this is supposed to vent this way? Any guidance or advice would help a lot
