code p0446 that's a small leak in the emissions?

Yep, when the arts are not available, (obsolete), You need to get creative.

Code: P0446 - EVAP Vent System Performance / Vent Control Fault

But since this this is a control fault I would replace the EVAP vent valve while fixing the vacuum supply, after clear the codes and the problem should be solved. Please let us know what happens.

it says evap emmission systems vent control circuit but u say change the valve to my issue is that I can't find a grommet to fit inside the back of the engine and stay it's as if there is pressure pushing it right back out but what's the name of the part you say to change as well

Yep, you have two problems you need to fix. The vacuum lines and the control valve, you can try the vacuum lines first and then clear the codes and if the code comes back change the valve as well.

the valve which one I can't seem to get the men at my parts store to comprehend anything I explain to them

This should help

ACDelco / GM Original Equipment:

214-2324 - GM/ACDelco vent valve solenoid (round filter type)
214-2308 - earlier design with slightly different filter shape

Aftermarket Replacement Options:

Dorman 911-062 - round shaped solenoid replacement
Dorman 911-075 - rectangular version (if your harness/shape differs)
Standard Motor Products 2573-05320346 - aftermarket vent solenoid equivalent

Notes for Ordering

These parts fit the 2000 Buick Century with the 3.1 L V6’s EVAP system (there were a couple of different designs over the years, round vs rectangular body, so verify what you have on your car).

Many vendors will list them under “Canister Vent Valve Solenoid,” “EVAP Vent Solenoid,” or similar names.

Let me know how it goes, Ken

the hose I'm dealing with is a part of the pcv system but it's not connected to anything other then the air filter housing and the back of the engine it has no harness or plug of any kind my only issue is getting the end that goes in the engine to stay in it no matter what grommet I've tried it just pops back out

This code is for the evap system not the PCV system, can you upload images or short video?

Code: P0446 - EVAP Vent System Performance / Vent Control Fault

, Ken

is this it because I can't find this part number online and it's the closest thing I see under my hood that looks like it

that doesn't connect to the pcv valve or it's hoses

Idk why but this phone will not let me upload a video on here

What kind of phone do you have? Also, this is the EVAP purge solenoid (purge valve) so this is what the code is for. I see a vacuum line that looks like it is taped? This will be no good, I would get a small piece of windshield wiper washer tubing at the auto parts store for the repair.

that's what I did but I taped around the ends to keep it from coming off and it's a moto g I entered the parts numbers you gave me on Amazon and it keeps pulling up parts that are not for my car they say however it did lead me to a part that is compatible and claims it will fix this code so I ordered it il upload a pic in a min cus it's got a hose connected to it that idk how to remove but the round 1 you mentioned I can't find a specific 1 thats compatible

so I ordered both these parts I believe I know the all black 1 that I asked if there's a hose that goes on that end is the right replacement part not sure it's what you meant or not and the other round looking 1 idk if it's the right 1 or not at all but it was closest in emissions that matches somewhat and Amazon said goes to my cars emissions lmk what u think

Yes, I am talking about the tube with the tape on it and the end of the video, it cant have tape on it because it will just leak vacuum. That line needs to be replaced or repaired with a small piece of vacuum line, just cut the bad part out and use the line as a splice. Thank for the video it helps. Please upload more once the repair is done, you may not need the valve, clear the codes after the line is fixed. Ken

that's what I'm saying I did replace it already but the tapes on some wires that happen to sit above that

Okay, good job, did you clear the codes and if so did you drive the car for a bit and the code stay gone? If the code comes back I would change the valve out, you can get one from rockauto

I have not changed the valve itself I got it from Amazon yesterday but can't figure out how to get 1 of the hoses of that's got a round clamp style hose on it can you help me do that safely

I did change the hard hoses and rubber ones on the old 1 already cause they had broken but not the valve cause that 1 darn connector

Can you upload an image so I can take a look?

yes I will but I'm in Oklahoma and we r in the middle of a freezing storm so soon as I can go outside for a minute wo freezing I will but it kind of reminds me of something similar to a fuel line type clamp it's plastic tho

Yep, I heard about that storm, stay safe and let me know when you can take the image. Ken

see this roundish plastic connector in pic #1 that connects to the pic #2 which is the part you said is likely the cause for code p0446 and then to pic #3with the green cap that has a black tag saying evap service port well Idk how to get this connector off and there's a open ended hole on the other end pic #4 is anything supposed to be there

Yep, the lines look better. So the EVAP system needs to be 100 sealed, it cant have any leaks so please keep that in mind. Also, looks at the O ring seals inside the corrugated line on the solenoid. This video can show you how to check for leaks on the system.

Please go over this guide and get back to us.

how do disconnect the hard plastic connector to it tho

I don't need to track down a leak I need to change this part and can't figure out how to. get the evap connector off of it to do so

O sorry, yes you squeeze the connector at the "loop" part this will release the connector without breaking it. Check out the images (below). Please let us know what happens.

I got t off. got the new on drove it got a check light again I'm going to run the scanner n see why n lyk

Okay, did you clear the codes once you where done with the repair?

yes it didn't come back on until I drove a lil bit maybe 20 min or so

So you still have this code?

Code: P0446 - EVAP Vent System Performance / Vent Control Fault

Lets check the ENG EMIS fuse in the fuse panel under the hood. This guide can help

https://www.2carpros.com/articles/how-to-check-a-car-fuse

Check out the images (below). Please let us know what happens.

yes code came back after resetting it and driving it a lil bit but can a fuse go bad or fail and be bad even if it's not burnt inside

Not really if the fuse is not burnt it is good. Can you check the gas cap seal, this is another point of failure for the sealed system. Keep in mind any leak in the gas EVAP system will cause this code as well.

I did and im not sure if it's missing or not il take a pic and send it in a min and let you tell me what you think could the cable from the gas pedal to the throttle body have anything to do with it

The cable from the throttle to the gas pedal will not have anything to do with the EVAP issue. Can you see if the pink wire to the EVAP solenoid has power when the key is on?
