Does anyone know the R and R procedure? I heard that you may have to remove the right axle which makes no sense to me. Thanks.

Anyone know the location and removal procedure? Thanks

Some LS430's came equipped with the charcoal canister, some did not. I can't specify which year or model they have been thought to be equipped on.

But any how, here is the location of the canister, and removal seems to be fairly simple.

Thanks but I have an 01. Has the Ultra package and the canister is in the rear. Getting P0446, 0441, 0440 and smells like gas at rear of car. Has 230,000 miles on it so sure the charcoal is saturated. I'm told it is above the right rear axle.

I have the same issue with my '02 Ultra so advice on repair is appreciated...

There was a post here yesterday with pdf diagrams showing the step-by-step R&R procedure, but it must've been removed.

Gotcha. Here's the diagram for it, maybe it helps out a little. The charcoal canister is part # 77740.

Good luck.

Some procedures I found in my manuals, hope they can lead the way for you.

Looking through those diagrams sure looks like you need to remove the axle to get to the filter. Sounds like a fun job. I could probably verify that when I have my car on the lift this weekend installing my RUCA.

The post by rkw with attached pdf R&R (before it was removed) stated 2 ways to remove canister. I didn't save that pdf.

Take the hose off leading to the canister at the engine side and the canister side and blow out with compressed air to make sure no charcoal particles have leaked into the system. If the line is clogged, you would be seeing EGR codes. I've had success on other cars placing a screen filter in that line to prevent particles from reaching the valve. The correct fix however is to replace canister if it's leaking and blowing out the system.

Bump.

Has anybody actually replaced the charcoal canister on an LS430, or is it a signal of end of life of the car?

I need to replace the charcoal canister assembly on my 03 LS430. I looked at the pdf images that were provided, and it says to remove the RH drive shaft (not the axle). That might not be too hard, will look for those procedures, but want to verify that is all that needs to be removed to get to the charcoal canister.

Thanks,
Andy

I have the PO440 code forever, most likely in need of the canister. My Indy told me it’s a huge job and no need to repair for any emissions requirements. It’s not getting replaced.

Thanks, Bocatrip. I live in Maryland, and am failing on emissions because of this. How are you getting around that, or do you not have emissions in your state?

​​​​​​ If it's just one emissions code you can pass. Here's how:
Fill the gas tank completely. Reset the code with a scanner or disconnect the negative battery cable. Drive the car so the other monitors can reset. A day or two of driving should do it. Make sure the fuel level stays above 3/4 as this will prevent the EVAP test from running. You can refuel if needed. You'll pass your emissions test as long as everything else is good. In Maryland, as in many other states, you can pass emissions without the EVAP monitor running. You can verify with a scanner. If it only has 1 incomplete monitor you'll be fine.
