is the canester vsv same as the egr vsv? I noticed on my 1999 camry they
both have 3 ports
Hey Mark I just had a P0441 CEL come up the other day. I’ve replaced the
gas cap and checked for cracks in the hoses around the charcoal canister. I
haven’t done a smoke test or anything like that, just visual inspection.
The P0441 trouble code has come back, what can I do next? Besides change
the canister.
2001 Tacoma 3.4L
Canister is in the engine bay with a couple switches/ valves on it. If I
can replace a switch to fix the issue that would be awesome.
Nice video. I have a quick question. I have an 08 toyota yaris with just a
PO441 code. The code reads leak or purge valve. Is the VSV the same as
purge valve. What about the solenoid? Are they all the same? My canister
costs 800. Im hoping its just the vsv? Thanks.
Hello, I have a 1992 Toyota Camry LE 2.2L that i took in for a smog test
and it failed emissions because I had no vacuum on the EGR valve. He showed
me the valve works when he pumped air into it the engine died, but i just
don’t have any vacuum recirculating it. Any ideas? Thanks i’d really
appreciate it:)
Is it possible to Do it your self Kuzz in the video you said I need a
hoist. Do you know an estimate of how much it would cost if I take it to a
shop
96 lexus es300 same code p0446 should i check my canister like this camry?
i need it smogged soon
Hello Mark.. My 2000 Tundra, (4.7 liter) has a faint smell of gas, both
from under the hood, under the vehicle.. No leaks at all. Checked under the
truck thoroughly..Checked the hoses on, and around the vapor canister. No
sight of gas leaking from the gas tank either… Like I mentioned, it is a
faint odor of fumes… Frustrating.. Thank you.
My car is Corolla 2009. Suddenly, The Eng. Liter comes up! The Toyota
dealer told me I should replace the Canister. The price is 400 dollars!!
Do I have any cheaper choice?
Nice video, can you tell me if the 2002 corollas have charcoal pellets in
canister and if so can they be replaced?
Thanks,
Stan
Thank you very much mr.
Can I clean or replace air filter on vsv system please
Hey guys.. Interesting video.. I know it was posted almost a couple years
ago now, but I am curious why at the time you didn’t smoke test the system
to check for leaks? As you mentioned in your video the code could be set by
a leak.. I recently had a 98 come threw my bay at work setting a P0446 code
and failing emissions cause of it.. It had been back and forth to the
dealer for the same code 8 times over 2 years trying to solve the problem.
with the 9 volt battery do you connect the pos to pos and neg to neg?
My 2001 Camry (LXE) just recently had its check engine light come on. Now I
have a bad history with Toyota dealership, and I wanted to check before I
pay them 600$ just to replace this crap. What bothers me is , my car drives
great, very smooth, the only thing I’ve EVER noticed is that the shift
between 1st and 2nd gear is pretty rough, also makes a grinding sound
coming out of park. Anyways,Toyota wants to replace the Cannister and Fuel
Cap (thats all) for 500$+ 99$+ for install. Is this right
@chapshow1 The EGR and EVAP are two separate systems. If you have problems
with the EGR valve there is no reason to think you will have problems with
the VSV. If you have any other concerns please let me know, Mark Hicks

At the Natural Vacuum Leak Detection (NVLD) assembly, which is mounted near
the fuel tank, backprobe the Violet/White wire with a voltmeter. Locate the
vacuum line going to the canister and remove the line so a hand vacuum pump
can be used to put vacuum on the line going towards the NVLD. The other
line at the NVLD goes to the vent. Block the vent line. Using a hand vacuum
pump, apply vacuum to the line while watching the voltage on the
Violet/White wire.
3. If both solenoids operate correctly and are not sticking, inspect for a
restriction in the Evaporative Emission (EVAP) lines that could affect how
the canister vents after a leak test is performed. 4. Verify that the fuel
cap is a factory part. If the fuel cap leaks or does not hold the correct
amount of vacuum when the system checks for a leak, all the codes will set.

Thanks. Given that the car (2001 Toyota Sienna) is due for an emission
test, I wonder if you have its drive cycle information? I appreciate if I
could possibly have this information so that the monitor may test its evap
function more quickly. Many thanks.
I apologize and completely agree. If the VSV checked out to be functioning,
the nest step is to smoke the system. You are also right the majority of
techs just want to replace a part without testing. I feel this is the case
for a couple reasons. 1. shops that only want to pay the techs for time
spent for R&R and are just interested in getting the next vehicle in the
shop. 2. The shop owners and service writers that have not educated their
customers that the best way to repair is to diagnose
Me too. But it might be time to have it smoked to pinpoint the issue. Let
me know what happens. Mark Hicks Wells Vehicle Electronics
My 2001 Toyota Camry LE gave out codes P0440, P0441, P0446. I took out my
canister and did the battery voltage test, and I heard the noise from the
solenoid, so does that mean that the canister is still good? If it’s still
good, what may be causing the problem?
Very good! Thanks for sharing your findings to everyone! Mark Hicks Wells

Hi, many thanks for your advice. Unfortunately, after driving 1000 miles
since mid-August when I replaced the VSV of the evap canister, the check
engine light is now on, with code P0446 (P0440 and P0441 pending). The
replacement of VSV did improve significantly (used to have light on with
codes P0446 series after about 150 miles), but there is still a problem.
So, I plan to buy a new evap charcoal canister within the next few days,
and replace it. Would you have any suggestions? Thanks!
Sure it could be the cap leaking. If not let me know. But give me the year,
make, model and engine size. Mark Hicks Wells Vehicle Electronics
Mark i got a 1997 toyota avalon nd my motor been shaking a lil sometimes
when i drive .its been doin it before i got the code u think it gots
something to do with it. My gas cap seems to b fine 2
Thanks for responding Mark… as it turns out my problem was the gas cap. A
trusted mechanic cleared the error codes and the problem has been resolved.
You replaced the right part. If the check engine light comes back on let me
know. Getting the monitor to reset can be a real challenge sometimes. I
suggest just driving it, it will eventually test and reset. Unless you are
going in for an emissions test. In that case I will send you the drive
cycle information. Mark Hicks Wells Vehicle Electronics
@markjhicks Everything tested good. Replaced injectors – still sputtering,
but runs smoother after initial acceleration. 🙂 Next venture is the fuel
pump strainer. Oh, and now I have an exhaust smell in the cabin.
