Camry 2012+ :: Check Engine Light On - Codes For EVAP Emission Control System
So mad today. Check engine light came on, plugged in my scanner, got P0441 EVAP Emission Control system Purge Flow Fault and P0455 EVAP Emission Control System Leak (Large).
8-month old '13 TCH XLE is getting a check engine light already.
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.
Oldsmobile - Stalls - Aurora :: 1998 - Stalling When Come To A Stop Sign Or Light
3 mechanics can't find what is wrong but when I come to a stop sign or light my car stalls, not every time but a lot. Also, seems to happen more in cold or wet weather. So every time I stop and idle I have to quick put it into park.
View 2 RepliesPassat (B5) :: 2001 - Emission Workshop / Misfire On 4 Cylinders And System Too Lean Codes
I am getting the dreaded emission workshop.
The codes i am getting are p0301-p0304 and p0171
Which are misfire on 4 cylinders and system to lean (bank 1).
Here is what I have done:
Got the 4 ignition coils replace, replaced the mass air flow, replaced the air filter, replace the plugs.
I just check the L wire and it doesn't have any cracks or holes
I don't know what to do next.
Elantra XD (2001-06) :: Random Misfire On Cylinder 2 / 3 And EVAP Codes
Trying to troubleshoot my 2001 Elantra (173k). I'm having intermittent trouble codes being set and I'm wondering if they may be related:
P0302
P0303
P0446
The cylinder 2 and 3 misfires are relatively recent. Plugs and wires are visually ok (and not that old). I swapped plugs 1 and 4 with 2 and 3 to see if the plugs are bad. It took 3-4 days, but the P0303 set again (and it's very intermittent - car will noticeably lose power for a few seconds, code set, then run fine for several days). I also sprayed carb cleaner on the intake manifold gasket with no change in engine idle, so the gasket appears to be intact.
I had read in a forum somewhere that the misfires could be related to a vacuum leak, which could also be setting the P0446 code. I removed the charcoal canister and inspected the lines - visually ok.
I bench-tested the canister control valve and it did operate, though I noticed some charcoal blocking the valve so it would not close all the way when energized. I used compressed air to blow the debris out of the valve and it appears to close properly now.
I went to hmaservice.com and noticed there are no instructions for the P0446 DTC. I've been using a Haynes manual instead. For quite some time now when refueling, the fuel nozzle shuts off every few seconds (I have to slowly put the fuel in to avoid).
Some questions:
- Can these codes be related?
- Based on my symptoms, should I replace the canister control valve? What about the charcoal canister and the charcoal air filter - should those be replaced as well?
- What else should I check?
Golf IV / Jetta IV :: Codes For Random Misfire And Small EVAP Leak Detected
Okay, so a few weeks ago, my tire blew out on the freeway. Of course my spare wasn't in there and when I got one I couldn't get the lugs loosened. My 4way was too big on all sides. It was late, I am a single mother of two young kids so I had no choice but to drive slowly to get it off the freeway. The next morning I came back fully prepared, got my car in to get a new tire. I have been driving with ONE code for my CEL, but at the shop (where I use to work) I used the scanner and it threw 5 codes.
P0300 Random misfire
P0442 Small EVAP leak detected (this one was already there)
P0420 Catalyst system below threshold bank 1
P0301 Misfire cyl 1
P0303 Misfire cyl 3
My beautiful love is an 02 Jetta 2.0 4 Cyl. Now, since 4 of these codes popped up AFTER my first blowout (I turn 30 next month, knock on wood)
Did driving my car at 5 mph about a mile and a half (everywhere up until the gas station was NO PARKING) do something to my car? All of a sudden, any in town driving ESP IDLING makes my check engine light blink and my car has no power I just have to pull over wherever I am. I checked the car out myself on the side of the road and my cat was glowing. After this I do not drive my car.
So, what should I do. I did a tune up. Should I replace the 02 sensors then the cat?
Prius (2001-03) :: 2002 Check Engine Light Codes For EVAP System And Misfire
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
Ford F-150 - 1997-2003 :: Codes For Large EVAP Leak / Cylinder 6 Misfire / Bank 2 Lean
Here are the codes I'm getting:
P0455 - large evap leak
P1451 - main control (evap canister)
P0306 - cylinder 6 misfire
P0174 - bank 2 lean
are these all related? Or two separate issues. I have replaced all the evap lines with new lines. I have a new egr valve, and exhaust manifolds, and what should I look at 1st
Oldsmobile - Stall - Gasoline - Pump - Misfire :: 1998 - Hesitates / Stalls / Sometimes Backfires?
My 88 "Rosie" has been having problems for months. It hesitates, stalls, and sometimes backfires. This is an intermittent problem, though it is happening more often lately. I took it to local auto shop and their computer showed Rosie was throwing a misfire code as well as a lean code. I took it 3 months ago, and I took it last week, got the same codes. The lean code led me to check the fuel pressure. I did and while it should be healthy 48-55 psi, I got 48 for awhile then 15 PSI! Now I'm thinking fuel delivery. I started with the filter. Sure enough it was dirty. Weeks later, the problem persists. I replaced the fuel regulator (ok, mostly because it was cheaper than the replacing the fuel pump, which I really didn't want to have to do.) Still, no luck, so I finally caved and spent $200 and 12 hrs dropping the tank to replace the fuel pump. Guess, what? Still no dice. I'm still getting the hesitation and the misfiring. I haven't put the fuel pressure tester back on it (been busy) so I don't know if the pressure is still low or if these other things are even related. I thought my logic was infallible. Let's face it, there's a finite number of parts that control fuel pressure. I'm running out of parts to replace. Where did I go wrong? The only thing I can think of that could still do it is perhaps the fuel pump relay? I dunno. Would it work off and on or fail completely? I'd love to get some opinions on this.
View 19 RepliesAlero :: 2002 - Emission Evap Not Ready?
2002 olds alero 3400 engine.....I had a code of a p1401 insufficient flow to egr ..Which is most of the time the clogged passage. I took the throttle off an accessed the egr passage. Boy was it clogged with carbon so I cleaned it out thoroughly, which fixed the problem.
I reset the computer I drove it a few days and now all the monitors are ready, except the evap monitor. I have drove a few days highway, street, stop and go etc my tank being half filled etc. And its still not ready. Car has to take emission soon. Its a coincidence because the Alero ac isn't working so it can't be turned on right now.I ran into a similar problem with a 2000 Monte Carlo the evap wouldn't go to the ready status he had a short somewhere and the ac compressor would work intermittently. The compressor finally worked one day with defrost on and the evap went to ready.
Passat (B5) :: MIL Came On - Code P0455 / EVAP Emission Control System Leak?
New owner of a 2003 1.8TPassat (29,000mi) as of the last 2 weeks and have just had my MIL come on. Scanned it at home with my Actron CP9125 scanner and got this code (P0455) which reads in the scanners manual as "EVAP Emission Control System Leak (Large)". Didn't know if this was a generic description of the code or VW has a more specific definition. What precisely this is in reference to, gas cap, vacuum hose????? Or what VW's actual description of this code is?

Just received a P0441 CEL (Evap Emission System Incorrect Purge Flow). I have a 2.7l engine, 2WD. I've read other forums and it seems it's most likely the purge valve or charcoal canister.
View 7 RepliesSanta Fe (CM - 2007-12) :: CEL On With Code P0441 - EVAP Emission System Incorrect Purge Flow
I've had the check engine light come on and was told it was probably from topping up too much and that it would go off on it's own... I should say I have no issues with idle or rough starts.
I had it scanned at Auto Zone. The print out shows: "EVAP emission system incorrect purge flow probable cause
1) Faulty purge control solenoid
2) Faulty vent solenoid
3) Blocked vapor canister
Previous posts suggest if it were a blocked vapor canister I'd have trouble completely filling the tank so I am hoping it's one of the others. Almost everything I see suggests the purge control and that looks like an easy fix. My concerns are a) if it is the vent solenoid - how hard is that to get at and b) what is the part number as I can't find it listed anywhere? I want to have both on hand before I start trying to fix this. Lastly if it is the vent solenoid should I just give up and see a dealer??

Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.
View 9 RepliesMercury - Villager :: 1998 - Random Misfire Codes That Would Clear And Return
Yesterday, i changed the spark plugs, spark plug wires, mass air flow sensor, air filter and replaced the in and out take coolant lines in the throttle body.
Before yesterday, i got random misfire codes that would clear and return, i have no a/c, i believe the thermostat needs replacing as the van runs hot after a while of running and quickly when idling and the upper radiator hose is hot. The van's idle is rough to the point that some one else turned up the idle so it would stop stalling so frequently, especially in reverse. it stalls very very rarely now.
then a few days a go i got a knock sensor code that clears itself and then returns.
A friend changed the distributor cap, and noticed some melting and corrosion, hence the spark plug and wire change. this friend also pulled the wiring harness for the front 3 injectors while it was running. the one on the far right created no audible engine change (also this spark plug was immaculate compared to the others), so he said it is bad (or is my friend a moron?)i had also noticed a coolant hose that would spray coolant when really hot.
So yesterday i tackled the above. In the process of doing this i had to rip the other coolant hose to remove throttle body, i replaced these with a self cut piece of 1/2 heater hose. after removing throttle body, i realized i needed a gasket. so got one of those.
a few notes:i used antisieze lube and dielectric lube on spark plugs, thread and ceramic respectively. the mass air flow sensor is used.i cleaned the throttle valve with brake cleaner (non chlorinated) because it was nasty! i did not remove the cables attached to throttle body, just moved it out of the way while working.i hand tightened everything.there were 2 skinny hoses i disconnected, one with a metal tip that went in to the large rubber air intake hose, and one that ran into the throttle body (this hose ripped like a 1/4 inch off it seemed long enough, so i did not replace). i disconnected the large air intake hose at 3 spots with pipe clamps.i disconnected 3 wiring harnesses 2 at throttle body and 1 at mass air flow sensor
Now, it seems the van is running smoother while getting gas, but rougher when idling. What did i miss? what would be causing a rougher idle? I am now at work, i will not be home till around 9 cst. So I cannot check anything.the van did throw another code, but i have not checked it yet.
Ford Ranger / B-Series :: 1998 - Codes For Lean Bank 1 And 2 - Cylinder 4 Misfire
1998 ranger 4.0L. I ran my scanner on my truck to day and my 2 bank 1 sensors seem to be bouncing between .150 and .700 but my bank 1 sensor 2 seems to be stuck at 680-720 and not bouncing, is this normal?
I did pull a code po135 heater circuit malfunction BANK 1 SENSOR 1 ...
Also I am not sure where my fuel trims should be...
My
ST1 10.0
LT1 25.0
ST2 12.0
LT2 25.0
closed loop.
When I first got the truck I pulled codes for lean bank 1 and 2 also a cylinder #4 misfire and the bank 1 sensor 1 heater circuit. I reset the codes and the heater circuit bank 1 sensor 1 popped the mil light in 5 min. So I am starting with the o2 sensors. I've not found any vacuum leaks at this point.
