I only replaced the fuel filler cap on my 2002 model Holden Commodore because it was an obvious fault, the O ring was split on the cap.
It runs the 5. 7 litre Chevrolet LS1 V8 engine but Holden didn't fit a fuel tank pressure sensor so the P0442 code is not applicable to my car.
Instead I got just a P0171 (not even a P0174) code which is a lean code, it's the only other obvious leak since I replaced all of the vacuum hoses & I had the inlet manifold off to do a hydraulic lifter change, so all of the seals & gaskets have been changed.
I replaced the purge control solenoid valve pipe with a piece of fuel hose because the old plastic one just vibrated & wore out in 2011.
In my car, the only other part other than the MAF Meter clamps which would leak air is the O ring around the fuel pump sender unit.
Yes, I've been looking into making my own smoke machine out of a jar of baby oil & a soldering iron!

Hello from Finland! Nice to have that smoke machine. Here is my trick how to find leak in EVAP system. Hook your scan tool to monitor fuel tank pressure sensor and use compressed air to find leak. Just blow the air to different components and when you see action on pressure sensor signal you find the sweet spot.

I just dealing with evap stuff for the first time on a friends Suburban. In this case its a p1441 flow during non purge. I assume its seeing the tank pressure go down with the purge valve closed. I checked the purge valve and it flows slightly when I suck on it, so we are replacing that first.

Non popular codes are Evap here in SoCal. Everyday occurrence with you. Great Video! It's 11: 40 PM, I'm sleepy, it's bed time! Your smoke machine's fantastic! What happened to the one from Redline? Or am I so tired I don't recognize it? Hi Mrs. O, great ending of this video with you in it!

I was watching a video of you about 2 years ago and you looked like you had no clue about the scope when working with big E (Ivan) and now you look like your ready to teach a class is it really that easy to learn and understand I'm just starting out and just wondering

Thanks for posting this. I know this a problem with my 2011 Colorado. I smell the fumes and have the same code. I wonder if this can also be causing my fuel system to lose pressure when sitting causing longer than normal crank times

ERIC. FABULOUS NEWS!
Ivan is going to Krown Dec 12th!
I hope he films it.
Think if every body Krowned, Fluid Filmed, Rust Checked etc etc Your Choice of Used Cars would be so much better.

Is there a scan tool that you can do everything on? You use a red one and this one is there a reason why you have both? I'm looking to get a scan tool that does everything or mostly everything

I just fixed this same problem on my 05 Colorado, rotted out the ring and tabs on tank. Replaced with after market ring kit, thanks for the video
