Camry :: P0440, P0441, P0442, P0446 Codes Detected
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 RepliesSanta Fe (DM - 2013+) :: Getting P0442 And P0456 CEL Codes
I hope its just a gas cap issue. I just purchased one online (should arrive next week). I also tried to add Dielectric Grease to the rubber seal on the gas cap to soften it up a bit but to no avail. I hooked up my OBDII code reader to get the codes and it would only read with the car fully turned on and not with just the ACC like other cars without the smart key push button. Is that the right procedure?
View 12 RepliesSonata I45 (YF - 2011+) :: 2013 - Error Codes P0442 And P0456 Came Up
This last May I gave myself a graduation present and got a 2013 Sonata SE. I bought it through my Dad's friend's dealership at a pretty good deal and loved the car for the first few months, then things went South pretty quickly.
I've had more CEL issues with this car than I ever did with my piece of garbage 2000 Grand Cherokee.
The first time the light came on, I brought it to AutoZone who said I needed a new Cannister Close Valve. I then took it to my local Hyundai Dealership (Not my dad's friend's, I recently moved up to Ohio and that dealership was in Alabama) who verified that it was indeed the cannister close valve. They said I didn't need to get it fixed because it actually had nothing to do with the engine, but they gave me the part number should I want to buy it and switch it myself to save a few bucks. I bought the part from them and drove down to visit my family in the summer with the CEL on (who are in Memphis) to have my family's mechanic switch out the part. On my way down I stopped to get gas and, unfortunately for me, the gas hose kept clicking off like the tank was full after a quarter of a gallon, which obviously wasn't right. I brought it to my Memphis Mechanic and had them switch out the part, which they also said would resolve my fueling issue. They said everything was good, but on my short drive home (less than 10 miles from the mechanic) the light came back on. I turned around and my mechanic said he'd look at it. They then told me that I needed to replace a sensor in the EVAP system and that should solve the issue. For the rest of my time in Memphis, and on the drive back up to Ohio, I had no CEL, but I still had the fueling issue, but nowhere near as bad as it used to be. Once I was back in Cincinnati, however, sure enough, that stupid orangish-yellow light appeared back on my dashboard. I took it back to the Hyundai dealership who then wanted to charge me $500 to switch out the charcoal cannister which they were saying was the problem. To my great aggravation, they were unable to tell me that would solve my issue, but that it "should" fix it.
Well, yesterday the CEL popped right back on giving the same codes it's always been giving: P0442 and P0456.
Ford F-150 - 1997-2003 :: CEL Codes P0304 / P0456 / P0171 - Misfire On Cylinder 4
So, my 2003 F150 4.6 that I just put back on the road after a four month break is running like crap. I took it off the road for the winter because it was missing (no codes) and didn't feel like dealing with it then but after running it for a day the CEL comes on. It shows the following:
P0304 - hoping it is a coil pack
P0456 - pending. Gas cap?
P0171 - pending. One bank too lean?
Does the 171 code possibly have to do with the misfire in Cylinder 4? I know it is impossible to tell yet but am hoping there is a potential connection.
Before I parked it in January, it was running a bit rough and stumbled on acceleration but never would show a code. Now all this. Going to change the coil first, tighten the gas cap, check for leaks and see what happens but is there anything common on these trucks that I should also be looking at?
Volvo - S40 :: 2003 - P0420 And P0015 (B) Codes

Prius (2001-03) :: Got These Codes P0440, P0441 And P0446?
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?

Toyota - Camry :: 2000 - Recurring CEL - Codes P0440 / P0441 And P0446
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.

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.

Kia - Rio :: CEL Codes P0300 And P0456 - Difficult To Start After Filling Up
2006 Kia Rio LX with 78K miles,
I recently performed several repairs in the car including replacement of the timing belt, all other drive belts (power steering, air conditioning, alternator).
Recently, the car has developed a new problem where it intermittently has been difficult to start, but only after filling up the gas tank. The engine cranks over okay but it seems like it might have vapor lock. It seems to occur every time we fill it up. Rarely, the car has appeared to run rough for a few seconds, the electronic control module seems to make an adjustment and then it runs better. The gas mileage has decreased from typical 28-32 miles a gallon down to 23-25 miles per gallon, despite getting new tires for the car.
Additionally, the check engine light has come on intermittently…once reset it stays off for up to two weeks then will come back intermittently with the following codes:
P0456 which indicates a problem with the fuel evaporation system, which may be related to the gas cap (sometimes when this comes on, the gas cap appears to be loose, but other times it appears to be tight).
P0300 which indicates in engine misfireP0301 which indicates in engine misfire in cylinder #1P0302 which indicates in engine misfire in cylinder #2The first time that I received this warning, I replaced the 4 spark plugs and the check engine light did not come back on for a couple weeks.
I have also previously received a code for faulty oxygen sensor temperature regulation for the forward most oxygen sensor. From what I have read, this may be related to oxygen sensors were related to an exhaust or intake leak. I have attempted to carefully inspect the intake and exhaust systems and I don't find evidence of leak. (From what I have read, a lean fuel condition which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open are possible causes.
I have visually inspected the 4 coils/plug wire units and they all appear to be intact and since the engine does not run rough (it idles smoothly, seems to have normal power etc.), I believe that they're all functioning.Any thoughts about what should be my next step to diagnose and to fix this problem?Replace gas cap?Replace oxygen sensors?EGR valve?Could this be related to the timing belt replacement (CEL did come on prior to the repair but gas mileage and problem starting after fill-up has started after the change)? Carbon canister or solenoid valve for evap emissions needs replacement?(I have never been in the habit of "topping off the tank").
Lexus SC430 :: CEL - Evap Emission Control System Malfunction Codes P0440 And P0446
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.
Accent LC (2000-05) :: Throwing Codes P0441 / P2096 And P0442 - Exhaust Leak?
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.
Celica :: 2000 Toyota GT Sputtering / Jerking - Code P0420
I have a problem that has being going on with my 2000 toyota celica gt has been sputtering/jerking when going at a constant speed of about 60 mph. The problem is interment. I have changed everything from cam sensor when it came up on the scanner. Also changed the fuel filter and fuel pump. I changed the spark plugs. No luck the problem went away for about 2 weeks when I changed the fuel pump and filter but it came back. I got it scanned and the only code that comes up is P0420 which is a catalytic converter code. I have no clue where to go from here.
