Lui MRA: How much voltage should be going to the connections ? I've replace the canister and gas cap and light is still on ,Several mechanics are saying I might have a short in the system and want like 500$ !! That's nuts. Any help would be greatly appreciated!!

tornpixel: Hi there, I have a 2005 Corolla CE 1.8L A/T. I have received multiple codes for it in the MIL. P043E, P043F, P0441, P0455, P2401, P2402, P2419. Where would you suggest I start diagnosing? I have done a small amount of research, which has led me to believe that a large number of the fixes come from canister replacement (as described in this video). To give you some insight as well, I am finding it difficult to start the vehicle after refilling the tank at the gas station. Many videos are saying that if this is an issue, there is likely an issue with the "purge valve". Is the purge valve the same as the "vacuum switching valve" that is described in this video? Which would be attached to the canister, and therefore cause me to need to replace the whole canister? I was lead to believe that the purge valve is in the engine bay, but maybe there are two of them. Thank you
Jeisoon Herrera: I have p0441 on my scion xa... what can I do? :'(
MJ: please help. my 2002 Chevy prizm gets terrible gas milage and throws this code. The dealership didn't help. Does mine have early or late design system? Do I have to replace whole canister or can I just replace VSV? Can I do it on ramps? I don't have access to a hoist! I want to fix my car. It use to get 30 mpg in city and now I'm lucky if it gets 20!!
george lewis: Hello, I have 2000 Lexus GS300 and I got the P0446 code. I have a new VSV for replacement but I'm unsure of the location. Is it in the back next to the charcoal canister or under the hood? Also which is likely to fail 1st the VSV or the canister?
Robert Nunez: Hi,
Best video I've found.
I got a P0446 code on a 1999 Toyota Avalon. I removed the canister and tested the VSV by following a Chiltons manual. I thought it failed the Ohms test so I replaced it. I tested the new VSV following your video. After applying vacuum to the VSV Pressure Sensor and Purge valve hoses it held vacuum when the solenoid was activated then deactivated but when activated again the vacuum on the purge side didn't go to zero, it went to about 8.
Thinking I may have gotten a defective part I tested the Ohms and it was within specs. I then realized that the original VSV was checked using the wrong specs so I I rechecked it and it also was actually in specs so I reinstalled it to the canister and did the vacuum test. This VSV also did not return to zero. I hung at around 5.
I'm now wondering if this means I have a bad canister and/or if there is another test to isolate the canister. Please advise. Thanks.
Anthony Gualano: Hi, my 2000 Celica Gt has had a P0446 code for awhile now and of course it needs to get inspected. I see my canister is tucked by the gas tank and muffler. Is that most likely the problem and about how long is it to replace? Thanks
Cody Canary: Could a leak in the muffler cause this error code?
Christina Hamilton: Warning! This video does NOT get to po441!
PatMov: hello, What happen if I don't change this part ? any danger ?
worldofhurts: I tested the valve like shown in the video and it held pressure. When I connected the battery the pressure only went down to zero if I tapped the battery connection few times but the pressure on the other gauge when up.is this normal? Should the pressure go to zero without having to tap the connection more then once?
megaturdmaker: How much are typical repairs to diagnose and then REPLACE the cannister.... in other words.....worst case scenario on this code..... any idea on repair Range? I realize it varies but just a ballpark on the Fair price for job done would be great
Jeff Lewis: Hi Mark! I have a 2001 Sienna and am Getting code P0442 (sometimes P0440) as well as P0420. I think P0420 is the Catalytic Converter. Are 442 and 440 most likely the VSV?
Simon Xiang: I need to replace the VSV on a 2000 Lexus GS300, anyone has instructions how to do this?
DYAC: My friend's business did extremely well with adwords. He basically pay google to put his promotion ads on varies websites and the conversion rate is really high. I guess it helps since he sells gag/prank gifts and his ads get display on funny autocorrect websites. He wouldn't tell me the exact amount, but I'm estimating it is near the mid 6-figure salary. No risk no rewards I guess.
