Passat (B5) :: Mass Air Flow Sensor Burnt Out
May 13, 2007
I've had two mass air flow sensors burn out in my 05 TDI Passat. Dealer says it's faulty wiring in my vegetable oil conversion. Sensible?

View 1 RepliesI think I'm getting bad gas mileage on my 03 passat... I don't think it's my imagination...? I'm gonna keep track of how many miles I get next time I fill up, how do I know if I should look into a new MAF sensor?

Mechanic says I have many codes going off but thinks its the MAF. Already spent a bundle (misdiagnosed or ripped off) on other non related stuff that was supposed to fix this problem.
Mechanic says 90% sure but part is non return able. Need to know where to get the MAF cheap and quickly. Also part number or other identifying information so I don't get the wrong one.
I cleaned my k&n air filter on my 02 passat 1.8 turbo let it dry oiled it very lightly, and 50 miles later I get a check engine light on, pulled the code 16486 and it says Mass or Volume Air Flow Circ Low Input. Cleared the code put a frame in until I can get it filter. Why that would throw me that code, k&n oil gumming up my sensor??
View 2 RepliesI recently picked up a 2000 jetta vr6 for a very good price its a glx I have owned a vr6 before and done timing chains myself on it this one is a glx , I am having 5 fault engine codes on my vagcom they are cam position sensor , knock sensor, secondary injection pump, and mass air flow it ran fine 100 miles yesterday this morning the epc came on then went off and ran bad can these codes all be related or do I have to replace each sensor individually..
View 9 RepliesNeed to diagnose an issue with my 2012 GTI its got 39,000 miles its stage 2 Unitronic tune. So I was driving like an idiot coming home one night and i jumped a set of train tracks. Bent my plastics a little and when I cranked my car the next day my CEL was on. I noticed my intake was much noiser than usual. My buddy checked the code and said i needed a new mass air flow sensor. We replaced it and my CEl came back on within 20 minutes of replacing the sensor.

View 4 RepliesOil leak.... I can not locate the MAF sensor in my 2012 gls 2.4l sonata. I followed from the front tube intake through the air box to the throttle body and i do not see one. I also have the service manual and no mention of said sensor!
View 14 RepliesCleaning the MAF on the GX460? I have seen videos on youtube but the MAF positioning on the GX460 is a little hard to get to. I am wanting to clean the MAF because I am still experiencing some sluggishness. The vehicle's response had improved after a fuel induction and a spark plug change but it is still sluggish when compared to other GX's I have test drove. It is sort of inconsistent. Sometimes, it drives super smooth and the gears quickly shift other times the gears take forever to upshift and downshift.
View 1 RepliesOk so I just replaced my mass air flow sensor about a week ago. My check engine light just came back on and when I scanned it it said mass air flow sensor. What could be causing this to happen again? The codes are P0102, P0440, P0440.
View 4 RepliesWhat is that called? Mass air flow sensor wiring harness? I google 2011 vw gti MAF wiring harness, and i get nothing, or crap thats almost not related to what im looking for. While I was installing my intake, I accidently cut half of the wire to my MAF located behind the battery. Why I was cutting, dont ask, i was impatient. Anyways, what is it called? I want to replace my MAF and the wiring that leads to it.
View 1 Replies2006 Sonata with 3.3L V6. How to remove the MAF sensor on this engine? I see it right between the air cleaner and the throttle body input but can't get the electrical connector off for one thing. I bought some MAF cleaner (don't use carb cleaner) and did this on my other car (a Saab) and I cleaned the throttle body butterfly valve at he same time (with Valvoline carb and Throttle Body cleaner spray). It really needed it. I use a lightly oiled K&N filter on the Sonata and I hear it's even more important to clean the MAF sensor it under these conditions. You just blast it with the spray and reinstall.
View 9 RepliesI had to have my 2009 Prius towed 2 days ago. It has just over 73000 miles. I was on the highway and suddenly experienced a lack of power. Eventually, the dashboard lit up: check engine light, big red exclamation point, and my favourite: it said "problem" on the center display. I pulled over and let it sit for a few minutes and tried starting it.
All the same warning lights came on. The battery level was at 1 bar. The gasoline engine would start for maybe 10 seconds and shut off. I could move the car on battery power only, but I had several miles to go before the next exit, uphill, so I figured I needed to be towed.
Long story short, my dealer said all this is due to a failed mass air flow sensor, and is going to replace it. Does that make sense? I thought a faulty sensor might make the car run roughly or whatever, but not actually prevent the engine from running.
Got told by the dealer I need to replace my Mass Air Flow Sensor...to the tune of $657 dollars. And get a throttle body cleaning.

View 2 Replies"VSC OFF" light came on the other day. I took my RX350 to the dealer. The dealer said Heater Element sensor is bad. They didnot have this part in stock. I googled this part. Nothing comes up under that search. I took it to Autozone and the code came up as Mass Air flow sensor. Are both of these same thing?
View 7 RepliesSo, I've got a new toy (FORscan ODBII software) and a new code that isn't turning on the CEL (yet) but also didn't show up in OBDWiz either.
P1100 - Mass Air Flow (MAF) Sensor Circuit Intermittent
I cleared it, drove a few miles, checked again and it's set again.
The little troubleshooting advise window in FORscan says to monitor the MAF voltage while wiggling the MAF harness and see if the voltage goes below 0.23v or above 4.60v. I was unable to manually make that occur, no matter how I tapped on the MAF or wiggled the wiring.
However, in oscilloscope mode, look at this (at idle):
It sure looks like it went below 0.23v here. I have no time tonight to do any research. This is a relatively new MAF (one week old, Delphi unit). I think I'll swap it out for one of my two old OEM MAFs sometime this week. But if any opinion about this, pipe up. I do damned little work with scanners these days, and the tech keeps changing.
Im trying to change my spark plugs in my 2.0T. For some reason I can not figure out how to undo the mass airflow sensor from the connector and the same for the spark plug coils.
View 1 RepliesI'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.)
I am throwing a code for long term fuel trim being out of whack (code 17560) and I am trying to determine whether the MAF is causing it.
I pulled several redline runs while logging flow rate in vagcom. According to Ross tech's site they suggest that your flow rate should be around 80% of the engines rated horsepower. So approximately 200 g/s. I did several runs and never broke 100 g/s so what I should be seeing or has run into this code before.
So i got the UM tune done to my car then went and got my TT cams installed. After giving me car the 50 miles to adjust for the cams i get a CEL P0103 Mass or volume air flow circuit high input. Checked the connections around the maf and im noting seeing any broken vac lines or anything out of the ordinary.
Cleaned the maf and cleared the code but the CEL popped back up, got a new maf just because I like spending money on things i dont need and the CEL is still there, low speed or high speed it will pop on.
Is there anything I am missing that could be causing this problem or something i can try other then take to the place that did my cams?
