Jetta - Volkswagen :: 2001 - Check Engine Light Came On For Mass Airflow Sensor
My engine is in trouble. A few weeks ago, my check engine light came on. The diagnostics revealed that my Mass Airflow Sensor was done for. I replaced it, and everything was working fine for a week. Then a couple of days ago, my Electronic Power Control (EPC) light came on. The car is really dragging. It have to gun it to make it go above 60 MPH. It's become scary to drive on highways. Are the two issues potentially connected?
View 1 RepliesPrius (2004-09) :: Symptoms Of Failed Mass Air Flow Sensor?
I 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.
Sonata NF (2006-10) :: Check Engine Mass Airflow Sensor?
Got a check engine light and ran the codes and here's what I got.
P0174 fuel system too lean bank 2
P0171 fuel system too lean bank 1
P0174 fuel system too lean bank 2
P0171 fuel system too lean bank 1
P2187 fuel trim malfunction system too lean at idle ( additive )
P2189 system too lean at idle (additive) bank 2
Suggested parts maf sensor.
So im not getting any of the usual signs of a dirty or bad maf sensor. Power is fine engine is responsive and gas seems to be doing alright.

View 6 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.)
Chevrolet - Lumina :: 1996 - DTC Code P0101 - Mass Airflow Sensor Malfunction
So I have a 1996 Chevy Lumina (3.1L V6 engine) and I keep getting a DTC code P0101, which is a Mass Airflow Sensor malfunction. It's rather annoying because every time this happens, my engine shuts off. I'm talking no power steering, no power breaks, no acceleration, nothing. So I replaced the mass airflow sensor and it continues to stop about every five minutes. However, it does something odd and that is that the car drives just fine when it's in Overdrive and stops when it's in regular drive. I don't know if that's important, but I thought it might diagnose the problem.
View 4 RepliesBuick - Regal :: 1996 - CEL Code P0306 Cylinder 6 Misfire Plus P0102 Mass Airflow Sensor
Ok, my 1996 Buick Regal is acting up. I got a CEL, which was a P0306 (Cylinder #6 misfire), took the car to my shop, and they diagnosed as a faulty Ignition Control Module. Fast Forward, a day later, the car now has a hard start problem and throwing the same code, plus a P0102 Mass Airflow Sensor.
So my questions are:
1) Could a faulty ICM cause a single cylinder misfire, did they just replaced a random part? I would think a bad ICM would a multiple misfire considering on this car each coil controls 2 cylinders.
2) Are the two codes related? ie fix one, and the other would go away? or are they separate issues?
3) What could be wrong with my car?
This mechanic has been in my family for years, however, I'm not very pleased that a day later, my car seems to have more problems than before. Am I being too harsh?
Ford - Explorer :: 1998 - High Pitched Whine Type Noise Coming From Mass Airflow Sensor
There's a high pitched whine type noise coming from my Mass Airflow Sensor. I can get it to go away temporarily if I goose the gas pedal, but it comes back after a minute or two. Has not affected drive-ability, but it's pretty annoying. It sounds like the hot wire is probably vibrating. Is there any fix for it, or do I have to replace the sensor to get rid of it?? Have tried cleaning it, but that did not work.
View 6 RepliesFord Excursion :: Code P0102 - Mass Or Airflow Circuit Low Input
CODE P0102 "Mass or Airflow circuit low input" That was the code and upon checking my records prior to storing it for the year. I installed a new IAC,MAF, Fuel Pump and lots of new hoses, PCV, Fuel injection regulator. The Vehicle has only 110K miles. Now here is the clincher, after doing just the fuel pump it ran perfect for at least 25 miles, perfect I say. When I shut if off I got the check engine light, and thus the code which led me to install the other stuff. Now after pondering the matter, seems that it acted in a similar way PRIOR to my doing anything but there was no code previously. Like maybe some strange electrical connection, or something.

Need 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.

Cleaning 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.

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.
