Toyota - Camry :: 2000 - Recurring CEL - Codes P0440 / P0441 And P0446
Oct 15, 2014
I 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.

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.

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?

I have a 2002 Echo with 185K miles on it and i have a 2003 Echo with 101K miles on it, Both have P0446 P0440 P0441 codes coming up on them, the 2002 I replaced the gas cap, VSV valve and the rubber hoses from the throttlebody to the hard plastic line in the engine bay, and the 2003 I only replaced the rubber lines in the engine bay.

I have a 130K+ 2002 SC430 in which I recently started to smell gas in the cabin when air vents were set to pull air from outside. Within two weeks, I got the check engine light with two codes, P0440 and P0446, which mean "Evap Emission Control System Malfunction".
In doing some research the check light light could be everything from a gas cap which is not tighened properly, to a bad "charcoal canister " (whatever exactly that is), to a cracked or disconnected "Evap Hose". The only other SC430 related thread I could find on this topic is [URL] ....
If it factors in, I only use 93 octane gas. Interestingly enough, the check engine light came on within 30 seconds of me using the window washer to clean the windshield (at highway speeds), likely a coincidence.

My camry 2000 recently the engine light's on and the codes are P0446 and P0401
P0401:The PCM has determined that there is insufficient flow in the exhaust gas recirculation system.
P0446: The PCM has determined that a malfunction exits in the electrical circuit fo the vent control in the evaporative emission control system.

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?

Car - 2004 Accent auto.- 1.6l - 97K miles
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?

Check engine light was on for some time when I had filler neck and cap replaced. Computer sensors did not re-set until 501 mile mark, when light came on again. Checking the web, I find that some who appear to have knowledge of problem say it could be hoses, sensors, valves, or evap canister--the charcoal canister.
Mechanic who did original smoke test and recommended replacement of filler tube wants to replace evap canister without checking anything else. What should I do? At wits end, and car needed to pass inspection 2 days ago. Car has 157,000 miles or so...

Currently 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.

2001 Camry 4 cylinder. Check engine light came on yesterday. Advance Auto pulled out the code P0446 for the evap. emissions system vent circuit.
The car has no symptoms other than this and is current on all maintenance, but obviously it is a 10-year old car and so it goes.

I had my 2000 Toyota Camry with 133,921 miles on it seen because of the check engine light.The codes obtained at the repair shop were:
P0136: Oxygen Sensor CKT Malfunction Bank 1 Sensor 2
P0446: Evap Control system Vent CKT Malfunction
They then ran a smoke test and found that the charcoal canister was leaking and needed replacement. The mechanic said that not doing the above would not affect the car's performance or its safety but it would not pass inspection with the check engine light on and with those codes.

So over the last couple months every couple of weeks my car throws a couple codes:
17497 - Mixture Regulation; Bank 2; Range 1: Lean Limit Exceeded
P1089 - 001 - Upper Limit Exceeded - Intermittent - MIL ON
17559 - Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too Lean
P1151 - 001 - Upper Limit Exceeded - Intermittent
If I clear them things are fine for a week or two, then they return. I'm gonna check my intake, as I may not have a good seal on all the couplers (EIP CAI with the replacement for the accordian pipe). Otherwise I'm thinking injectors?
As to the noises, with the key turned to ACC ON but without turning over the engine I hear a steady ticking. It sounds like a mechanical clock, and it's coming from behind the brake fluid reservoir. During the VAGCOM autoscan the ticking noise speeds up while it scans the ABS system. There are no codes on the ABS, but I've never noticed this ticking sound there before. It it normal?
Lastly, after turning off the car I could hear a little motor. It's at the front, and after popping the hood I could hear what I assume was coolant flowing through the piping behind the radiator on the driver's side, however, the fans are not running. I assume if the coolant is flowing the car is in its cool down phase and the fans should be on at low speed. Since they aren't I'm assuming I've got the common fan issue. Does that sound right or is it normal for the coolant pump to be running without the fans?

The check engine light on my sons 03 celica is on. Went to autozone and they got the codes for me. They are P0420, P0442, P0446, P0456. I realize that I should probably have an OBD11 reader. What steps do I take to fix this?

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.

I have a 07 Mazda3 with 120k miles. I had a staring problem first time in gas station like 2 weeks ago and since then only anytime that I go to gas station. After car leave the gas station every thing is normal. Since then the check light popped on too. I have diagnosed it, it gave me two errors P0177 and P0446. I have check the gas cap, it is sturdy. Even I replaced the cap and have reset the check light. But it came back on still same errors.
As I've mentioned there is an old discussion in in your website, but it's closed. For refresh you can check it here if needed [URL] ....

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?

Shop 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?

I was looking for some diagnosing the problem with my car. I've already gone and put one of those autozone scanners on it, and it gave me a very vague idea of what could be wrong. It pulled a P0440 and P0507 code. I go to work and school full time so I don't have the time to be poking around at everyone of those possibilities.
The check engine light came on a few months back, the acceleration has been bad since then, but it just recently started running worse. While accelerating the car jerks horribly, but then will smooth out if I give it more gas or let off a little bit.

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.
