I've been having P0441 & P0455 codes showing up on my 2007 Corolla CE. My code reader tells me the areas that need checked. But, I can't find the vacuum switching valve on it so that I can check it for problems. Somebody said it's under the hood, but I can't seem to locate it.
Is is possible that it's mounted on the vapor canister (which I have located above the rear axle)?
I just bought a used Toyota Corolla 2002 CE with 120K miles two months ago. the car seemed fine and drives fine too. After a while I found out that the seller had removed the "check engine" light, so I read the error code by a instrument and I got these errors. 171,420,441. And I noticed that the engine burn a quarter oil every 200 miles on long drives!I checked the VSV valve and connected hoses but no problem there. Since the car has just 120K miles, I'm not sure that the piston rings are worn out! I'm wondering what could cause all of these errors?

After battling a few months to get my check engine light - fault code P0304 to go off I finally remedied the problem with 3 bottles/fill ups of STP Gas treatment. This was about 1500miles ago. I go to DMV Inspection station and sat for an hour then wait anther 20minutes for the test to end and was given the big fat rejection sticker, she failed because the check engine light came on with fault codes P0304 & P0441.
Now what the heck happened here? Just bad luck and coincidence or did their test set it off? Anyway the P0441 code is new and researched it is the Evaporative Emission Control System Purge Valve. Okay where is it, the HMA manual is not specific? In relation to the intake manifold where is it? Easy fix? And will this solve my P0304 code?
I have the 2011 Santa Fe V6 and it has the P0447 & P0455 codes popping up on my reader. I checked the pins to make sure that there is voltage getting to the solenoid, (about 11volts at the 2 pins) and it seems good. No fuel lines broken, or cap messed up, etc.
View 6 RepliesI have a 2000 Toyota Camry with 90,300 miles. Last week check engine light came on and mechanic said it was P0440 and charcoal canister needed replacement. Did the repairs and 20 miles and two days later CEL is on again. Take it back to mechanic and codes this time are P0441 and P0446. I'm told I need a new gas cap, so it's replaced with new one from dealer. 15 miles later, CEL comes back on and I return to mechanic. This time it's reading all three codes, but they can't find anything wrong. The only parts not replaced are the vacuum seal valves, which mechanic says test as good. They reset lights and 15 miles later, the check engine light is back on. My mechanic is baffled. What the problem could be or what they should check? Car drives fine, but light coming on is annoying.
View 16 RepliesJust turned 80k and recently noticed a bit rougher at idle. Other than that all has been fine. Plugs, etc. all original. Engine and VSC Light. Autozone ran the scan which turned up the above stated codes. They are defined as Evaporative emission control system pressure. He said it could be a loose gas cap. Checked it and its tight as a drum.
View 3 RepliesAbout two weeks ago, while driving on a hot, humid summer night, the check engine light in my 1998 Toyota Corolla came on. The following day, I took it into my mechanic, who plugged it in and came up with the code P0441 (Purge flow fault). He told me it was likely related to the fuel vapor canister, though I see this can also have to do with vacuum lines for the purge valve and canister or a bad purge valve itself. My gas cap was, and had been, tight, so it wasn't something as simple as that.
Reluctant to deal with this immediately, I went back to driving it, and lo and behold - the light went off after several days! Unfortunately, the light came BACK ON after several more. And most recently (a few days after coming on again), the light has now gone off!
Both times the light has gone off, the weather has been rather wet, but otherwise, there doesn't seem to be a clear pattern. What this on again off again pattern might say about the problem?
As far as trouble shooting faults in the ABS - does it store fault codes and how can they be read ?
Daughter's 2007 Elantra has ABS symbol lit for a week, I took it to a car wash and used the high pressure spray to clean the wheel hub areas and that may have fixed the problem but interested if ABS fault codes are stored and can be read.
I replaced the purge valve a while back, i just replaced the ccv and gas cap. The light is still on. Could a bad Ftps cause both those codes? Do i possibly have cracked/bad lines?

I recently replaced my neutral safety switch, but wasn't able to run codes at that time. The fuel level sensors need to be replaced, but haven't gotten to it yet. The usual P0463, P2068, and P0464 codes are active.
The following greyed out codes came up in a scan, and I searched this forum (and google) and found little info.
Mystery greyed out codes are: C2820, P2019, U1904.
Codes were reset with no problem...
After running to operating temp, if the car is turned off then restarted (like you would at a gas station, which is where I notice this) the engine will turn and turn and turn but not fire. I have noticed that stomping on the acceleration will cough it into life during this procedure. This doesn't happen every time and I have recently run high octane gas during a long distance trip.
106K miles...
Recent p0441 fault codes and gas cap warning light...
No other problems or codes...
So one day when I was driving, the CEL comes on, and then I go to autozone to get my free diagnosis. I got codes: P0441 and P0171
My engine is running fine and everything else seems to be in order. However, I have to get a new canister purge valve and new oxygen sensors, in order to be in the clear.
For the Oxygen sensors, I have AN IDEA of where they're located; somewhere underneath the car, by the catalytic converter (the converter is in between the two connectors, apparently). I have yet to do this and would like some opinions on what to do for it.
For the Canister Purge Valve, I have no clue where to look. I pop open the hood and I notice a diagram with labels. Great, but there are just too many other pieces to look at...I do not know if it is visible as soon as I pop open the hood, or if I have to dig deeper, or even if I have to remove the fancy plastic thing that covers the engine.
Just bough a new (to me) Touareg yesterday...2008, 75k miles, good service history. Drove home from the dealer no problems. Driving that same night (last night) the CEL comes on. Ok, I've had VWs before, CELs don't really make me panic.
Get home and scan the car and it comes back with P0327 (knock sensor 1 circuit low) and P0441 (evaporative emissions system incorrect purge flow).
I have a feeling it's got less than premium gas in it....I'm gonna throw some octane booster in the remaining 1/2 tank and see what happens. Anything else I should do?
I recently picked up a 2001 Prius to learn more about it. I've been trying to resolve the following codes: p0440, p0441, p0446. I used a new OEM gas cap & did a smoke test and smoke is coming out of the perimeter of the filler mouth and what seems to be a plastic ring with slots around the mouth.
My question is this:
1. Is this normal?
2. Does this indicate that the filler neck is bad?
3. Does this indicate that the charcoal canister is bad?
4. A bad VSV by charcoal canister?
5. Is it something else?
2003 Camry LE, 4 cyl, 165k miles – Got all of the above codes. Obviously checked gas cap and no issues there. Checked both VSV underhood and had clicking. Checked VSV at canister under vehicle and no clicking. Used a Dremel oscillating tool with flat metal blade to cut off rusted Philips head screw. Removed VSV and checked by jumpering to battery. No clicking, but did draw a tiny arc. That told me it was “trying” to actuate. Sprayed PB Blaster into hose fittings of VSV and mowed the lawn. Came back to VSV and it now actuated – but very slowly and delayed. Sprayed electrical contact cleaner in hose fittings with the VSV jumpered and open. Activated VSV several times and sprayed contact cleaner through the hose fittings several times – both directions. VSV began to active quickly. Put VSV back on vehicle. SES light went out by itself after it ran the EVAP test.
View 3 RepliesShop said o2 sensor and they just want to replace one. I can get universals for around 80 each, will they work if this is in fact the problem?
View 1 RepliesMy Corolla has the P0441 code, but not the typical 0445 code that comes with a loose gas cap. I cleared it and it came back (yes, I checked the gas cap). Googling the issue, I found service bulletin SB 0392-08, which implies the ECM could need to be replaced if the issue is not in the Evap system.

Error codes: P0301 ... P0304 ... P0300 ... P0420
Symptoms: Car had short touch of the shakes in the morning, parked it for 8 hrs, drove half a mile, and it got the shakes bad and seems like it wants to stall out and the check engine started flashing. After a minute it went back to normal, and then the whole thing happened off and on the last half mile home.
Background: I was told the catalytic converter was in bad shape last time I took her in so I'm assuming that's it. Friend of mine suggested driving it hard to burn out impurities in the cat, but I'm worried about damaging the engine. Going to replace the sparks and spark wires (they're about due anyways).
Just tried to leave for work and my check engine light came on. Luckily I just got a scangauge and the error codes are P0441 and P0445. I checked online and for regular Prius is says it could be the fuel system, fuel cap, etc. I'm scared to drive it now and wonder if I should call Toyota Care to tow my car to service.
View 6 RepliesCurrently throwing both P0441 and P2096, just prior to this I was also throwing P0442.
Read around on web and decided the simplest thing it could be would be the fuel cap, may as well start there. Owners manual even recommends changing at 90k. Got a replacement from advanced (which is supposed to be built to OEM specs), re-set battery light stayed off, attempted to pass emissions but a few systems were "not ready". Was good for 80ish miles. Light came back on throwing P0441 and P2096. I re-tightened fuel cap and re-set battery, light went off.
Did some maintenance; spark plugs, air filter, oil/filter change and replaced the leaky oil pan. Keep putting on miles hoping to get to the recommended 200 mile mark before stopping by the emissions testing facility, 105 miles after re-set same codes came back. I'm almost positive I replaced a o2 sensor 2ish years ago for emissions. Also there is an obvious exhaust leak which could be a culprit. I seem to remember reading somewhere that a weak battery can cause problems with fuel pressure... not sure if it's true or not but for what it's worth I do know my battery is on it's last leg.
I'd like to avoid unnecessary fixes, it's only my winter car so as long as it's nothing major I'm not going to dump money in it. I'm going to take a guess and say the check engine light is coming on when these systems become ready. Plan is to try this re-set one more time hope for the best and if not replace exhaust or at least repair leak. Not sure on my next step for P0441 though. Vehicle is a 2004 Hyundai accent with 86k on it.
