Golf IV / Jetta IV :: Engine Will Turn But Not Fire / P0441 Fault Code And Gas Cap Warning Light
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...
Golf IV / Jetta IV :: P0171 Code Come On - Tapping Noise Coming From Engine
P0171 system to lean.
I already replaced the MAF so what else could it be I cleared it once and the cel came right back on. I have a stasight pipe from the catback on my car and the cabin started smelling like burning plastic and eggs every time I accelerate. I'm going on a road trip tom and was wondering if I'll be fine. The car has a bit more noise coming from the engine the usual more like a swiping tapping noise
Golf IV / Jetta IV :: Code P0441 / Intermittent Gas Cap Light
2.slow bev engine / 2004 golf gl / 105k miles
The car sat in a garage for 9 days. It had no problems before. Now I have a p0441 code that comes back after being cleared, and an intermittent gas cap light. Is there a typical problem that causes this?
Golf IV / Jetta IV :: Code P0441 After Timing Chain Replacement - Rough Idle And Reduced MPG
2001 Jetta GLX, 12v 2.8 VR6 Automatic, 157k miles.
Relevant Info: P0411 code, unknown if associated with my slightly rough idle and recently reduced mileage (down by 3-4 MPG). I see 2 N80 valves, one by the power steering reservoir and one behind the throttle body attached to the fire wall. I removed them both, got a tiny bit of what may have been charcoal out of the lower valve and tested both with a 9 volt battery. Both were closed with no power and open when I attached the battery. I cleared the code and it returns within 30 minutes.
Possibly irrelevant info:
Changed the timing chains 3 weeks ago and the code popped up just afterward. Prior to changing the chains, all I saw was a Cam Position Sensor code that is now clear. The slightly rough idle was present to a greater degree before chains were changed but has improved.
SAI solenoids look good but their little rubber hoses don't look fantastic. Could this contribute to the rough idle or is it not part of the vacuum system?
Ignition coil is new and all plug wires tested to about 6k ohms.
I've looked up other's experience with P0411's and have seen the list of possible causes. Wondering if I'm missing a possible cause, if I can test the system further without having to buy parts etc, if the reduced mpg's and rough idle are related...
Golf IV / Jetta IV :: 2002 - Got Error Code P0171 And Now Won't Start?
2002 Jetta 1.8L Turbo running fine. Then one day driving on the freeway at about 70, I try to pass someone and notice when I push the gas the engine lulls. I back off the gas and accelerate slower and I can get up to speed. Drive it all the way home and its fine a t low speeds. Turn the car off and try to restart it and it wont start. Turns over but wont start. No CEL or anything else, I check the codes and I have a P0171 (Lean fuel Bank 1). Where do I start? Also car is parked in an underground garage. No chance of a tow out of this place, it may soon be a Jetta tomb.
View 2 RepliesPassat (B6) :: CEL Comes On / Codes P0441 And P0171
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.
Toyota - Corolla :: P0171/ P0420 And P0441 OBD Codes - Excessive Oil Burning
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?
View 19 RepliesGolf IV / Jetta IV :: Getting Error Code P0420 Intermittently?
I keep getting the error code P0420. Cat below threshold.
I have replace both the front and rear O2 sensors and we reset the check engine light. While driving through the cycles to reset the sensors for them to be ready for DEQ, the check engine light came on again.
I am about ready to buy the Cat Converter, but it is really expensive and if there are any other things that I can try before replacing the Cat I would like to try that first. Any other issues associated with that code, or should I just replace the Cat Converter as my next step.
Golf IV / Jetta IV :: Pulled Over P0441 Along With CEL
So my engine light came on today while I was out so when I got home I plugged in my OBD2 reader and it gave me a P0441 code which in my Haynes manual says "Evaporative emission control system- incorrect purge flow." Before I got my scanner, I had the engine light come on and I took it to VW. It was the same thing last time. I couldn't quite understand the poor explanation given from the VW guy and so now that that code ran again.
View 2 RepliesGolf IV / Jetta IV :: Gauges Intermittently Dying - Code P1650
This is on a 2001 golf, 5 speed, ALH.
Just went for a drive the other day and the ABS light started to flicker on, and then it was accompanied by 3 loud beeps, which I understand is the ABS warning.
Then the gauges all died like I turned the car off, but the engine was still running. No limp mode, no stumbling, nothing.
The needles then bounce back to where they should be, and various lights on the dash flicker, oil pressure, battery, etc. Not any pattern to them, they all just kind of blink on and off randomly. Then it will stop and run fine for 20-30 minutes (longest I have driven it like this)
Sometimes when I put the key in the on position before starting it, the gauges will do the same thing, without the beeping, and it is like I am cylcing the key on and off several times, needles on the fuel and temp gauge bounce between zero and their actual reading (other gauges don't move because I'm at zero rpm and zero mph)
I have replaced fuses 11 and 15, checked battery voltage with the car off, idling and at 2000 rpm, 12.3 volts with the car off, 14.3 with it idling and at 2000 rpm
The cheap code reader at the parts store gave me a P1650 code, which is intermittent communication error on canbus (paraphrasing) which makes sense for the symptoms, but I know on these cars sometimes a totally different system in the car can interfere elsewhere.
I am going to check/clean grounds, what else should I be looking for?
Golf IV R32 :: Code P0441 - EVAC Control System / Incorrect Flow

View 3 RepliesToyota - Corolla :: 1998 - Check Engine Light On Then Off After Code P0441
About 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?
Santa Fe (CM - 2007-12) :: AC Blowing Fuse And Check Engine Light Code P0441
Have 2 problems that are giving me major problems.....especially with 100 degree heat in Dallas.
1. Ac stopped blowing cold last night out of blue. Still blows just not cold. Replaced bad fuse and drove for 5 minutes. Blew again. Checked out the control/ circuit board but looks ok. Really cant afford dealer.
2. Check engine light problem for months. Gas gauge wasn't working. Replaced fuel sending units and it fixed that but still light. Code says p441. Dealer said need solenoid valve. Replaced both the solenoid valve and the purge control valve. Still check engine light.

View 1 RepliesHonda - Accord :: 2005 - Getting Engine Code P0171?
So I recently changed the air filter in my car. Its hard to get to and replace. Its in a tough spot and I am not sure if I secured the cover fully and completely. I am pretty sure I did. Anyway, a week later I had my check engine light come on, it stayed on for a couple hours then went off. It hasn't come back on since. However, I went to the Autozone, anyway, and had them read the code. They said it was P0171, system too lean bank 1. Is this a serious issue? What are some common ways to fix it, if it is? The car is a 2005, Honda Accord EX. 4 cyclinders. PZEV version. It has 142,000 miles on it.

Golf IV / Jetta IV :: Transmission Hesitates When Going From 2nd To 3rd Gear
I have a 2007 Volkswagen Jetta MKIV with an automatic 4 speed transmission (m01), and the car has only 100,000 kms on it, was always maintained either by myself or at the dealer, and never abused...ever!. Recently, I noticed that the transmission, going from 2nd to 3rd gear (and only 2nd to 3rd gear) will only sometimes hesitate...meaning the engine either revs a little bit (about 100rpm...yes one hundred) right before it changes gear, or if I'm going up-hill and it happens, it struggles to find the gear from 2nd to 3rd. However, this does not happen all the time, in fact, if someone who may not be as informed about cars, drove the car, the may never notice it. I checked with VCDS and no fault codes for transmission, only 2 fault codes from the engine misfiring because I sprayed the engine bay with water a while ago, and water accumulated in the dizzy.
View 24 RepliesPassat (B5) :: P0171 Engine Code - Mass Airflow Sensor Failed?
I've been getting this error code recently ("Fuel Trim,Bank1 System too Lean"). I have a Scanguage, which let me get the error code, and I used it to reset the message - it came back about a week later. I took it to a local repair shop after the second time, but as I'd already cleared the message, he couldn't do anything. It came back about a week later, and this time I took the vehicle in as soon as the yellow light showed up (without connecting the Scanguage).
The mechanic said that he found both P0171 and P0172, and that the problem was a loose vacuum hose AND a failing Mass Airlow Sensor. They reattached the hose and cleaned the sensor, but said that the latter fix may not last - the light came back on two days later. I took it in again (this time, checking the codes, and found only P0171) and he said this confirms the problem with the sensor and he'll have to replace it ($280 for the part, plus labor, less a discount on the labor equivalent to the labor he put in to clean the sensor.)
