Good explanation. I ran into a similar problem on my 2010 Chev Silverado 1500 pickup. Had the check engine light on. I hadn’t had the truck too long. Bought new. Had the dealer check. They told me I basically had a tiny vacuum leak. That they reset and cleared the code. Me being from old motors asked that there wasn’t a serious oil pressure issue. They said no. That your alright to drive it like that. Said that minuscule leak to find it would be like looking for a needle in a haystack. They said if it comes back up bring it back and they’ll dig further. Wasn’t very long and it was back. Didn’t go back. Drove it like that a long time. Ran into other issues way later on. Local guy fixed those. Then with this he had a diagnosis tablet but started first looking that the gas cap was sealing. I said it’s almost like I smell gas when I fill up and I questioned if the feed in tube was cracked or something. Anyway he cleared it and it was right back. With what he could on the tablet we then changed the vent module. Had to cut the hanging spare down as it was located above that under the box. Got that changed. He said that was stuck open. He cleared the fault but at the same time took my hand mirror to try look at the fuel pump and sending unit that sits in the top of the tank. He said it looked like it was wet. I had it maybe a few days and the same fault. Well this next job just like you have here; getting to and pulling the fuel pump/sending unit will cost you plenty in a garage. Some people have been known to cut a hole in the box to get at it. Well he took and dropped the tank. Found the plastic flange that is on the unit, that sits against the tank when it’s dropped in was cracked about half way around. Saw the pics. Got that removed and replaced. End of check engine light issues.

You mentioned a circuit problem which can be technically correct, not so much a wire problem as a component electrical failure, my GMC Library shows a clogged Vent Filter and a Fuel Tank Pressure (FTP) Sensor for this code. I hope yours is different so I can add another repair to my Library, still watching......Well, no luck today. I wish you would have at least retested the sensor signal pin to verify a voltage change and the correct voltage that should come from the FTP at static atmosphere pressure, the bad sensor showed 0.25V if I am correct. If you perform a test procedure on a bad part, please follow up with the same test procedure on the NEW part as well so we all know what a good test looks like on a good part. We also do not want to waste our time to bolt up the fuel tank in this case just to read the scan tool and notice a problem with the new part, now we need to drop the tank again, order another new part, etc, & do the proper test procedure again before bolting up the tank, YES, PLS. Many of us simply don't fully trust the scan tool so we like to back up our testing with direct voltage testing at the sensor which you did half of the procedure. Thank you for all the videos that you produce, very much appreciated. SMA listed it as a GMC and Chevy, its been highlighted in my library to move it to Chevy only, your video will go in GMC LOL, kzfaq.info/get/bejne/aryRpraEvqjFnGg.html
@KITS_Auto_and_Truck_Repair9 ай бұрын
@DuaneDonaldson Good point but for me the voltage change on the scan tool's Fuel Tank Pressure sensor Data Pid after replacing the sensor was enough evidence that the problem was fix, the voltage went from 0.2v to 1.5v I believe!
@DuaneDonaldson9 ай бұрын
OK Brother, but I would verify the scan data before bolting up the fuel tank, love your stuff. But for training, I would measure volts since we all know scan tools are not 100% trustable. I just watched a video today, APPS scan data 0V, scope at ECM proper volt sweep, car drives ok, BAD ECM not calculating APPS data to the scanner so ECM logic also not fully trustworthy, no worries mate.@@KITS_Auto_and_Truck_Repair

Soooooooo what I'm asking is can I just change the part since it's telling me that it's one are the other, most likely it's the one by the fuel tank. Only because I don't have all the tools you have. ( So can I just change the part myself ) Thank for giving us understanding to this.

Hello Deo, I learned a lot from watching your video! I’m researching how to fix my P0446. On my initial scan of my vehicle it said it has “excess vacuum” and well it tends to spit gas back out when fueling. Would that be because the vent valve is bad? Would maybe need replacing? Would love to hear your opinion
