Chevrolet - Lumina :: 1996 - DTC Code P0101 - Mass Airflow Sensor Malfunction
Jul 27, 2011
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.

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?

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.)

I've got a 2000 VW Lupo, essentially a small Golf, with an 1.4 motor, automatic. 40,000miles. The car's got the symptoms of a dirty mass airflow sensor but, when I removed what the manual said was the air temperature sensor all I saw was the open end of a small metal tube. No mass airflow sensor. The mechanic at the VW dealer was also perplexed as the specs for my motor (apq) says it has one. At any rate, the car suffers from sluggish performance going up even moderate hills and doesn't get the gas mileage that it should. What else could be causing this? Also, does one need to clean the air temp sensor in the same way as the MAS?

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.

I'm wondering where the mass airflow sensor is located on a 2004 Pontiac Bonneville?

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?

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.

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.

Vehicle is a 1996 Aero* XLT, 4.0 engine with 155000+ miles. I'm getting the P0500 code with the OD light blinking. Tranny is not shifting properly. Did not look at the speedo or check the cruise due to worry about making it to my driveway. I have had ocasion to set the cruise to 45MPH and at times it will drop out. I don't know the lower limit on the cruise. Is this speed sensor the same as the VSS...

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.

I woke up and drove to a stop sign. When I tried to pull away the transmission raced like crazy, HIGH RPMS! But was barely moving. After about 8-15 mph it would finally catch 2nd gear. I check fluids frequently, and topped it off a few weeks ago, and when I finally got where I was able to stop, I looked and there was no fluid registering. So I put 2 quarts in to fill.... Then started the car and it would not go into any gear completely. I'd just feel a small thump, when I shifted. It will actually drop into gear after a while going straight, but it's stil revving HIGH and it won't completely go into reverse. Weirdest thing, the "Anti-Lock" light came on while all this was happening...

Is there a way to clear the " check engine light" code if I dont have a instrument? Can I disconnect the battery and will that do it?

I am having trouble with my air conditioning system in my 1996 Chevy Lumina. When I turn on the AC, the compressor clutch does not engage and the fans do not spin. I was able to jump the compressor so the clutch engaged, however, the fans still did not spin and the AC was not cold. I then jumped the low pressure cycling switch (near the accumulator), which caused the fans to spin while the compressor was running. However, this still did not produce cold air from the AC and none of the AC lines were cold to the touch. I am starting to think the system is low on Freon, but I do not have gauges to test the pressure.

"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?

So, 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.

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??

recently started getting a 336 code indicating crankshaft positioning sensor out of limits.
removed the 7x sensor but it seems ok and the car does start ok. checked the ECM input of the 24x sensor and I never get anything but straight 11.2 volts when crank turns. checked at the 24x connector and get the same. (green lead on B connection).
problem I have is getting to the sensor. The crank pulley bolt just will not let go! I've tried impact gun set to max,(typical DIY type gun, not the best) and tried a breaker bar with hammer. how to get the crankshaft balancer off.

My 2008 chevy aveo has electrical problems, I think, sense I purchased it. First off the clock goes on and off randomly and doesn't keep time. Then the engine light is on one day then off the next. Sometimes on hot days sometimes on cold days. took it to Autozone and they have said two different times said there is a something wrong in the fuel sensor ??? took it to the Chevy dealer 3 time, Once they keep it for 3 days and said they couldn't get the engine light to come on.. ei. nothings wrong. the second time they said it was the sparkplugs and they charged me to replace them. 10 minutes after I got the car back the light came back on. The third time, again they said they can't find anything wrong.So the light as been going on one day and off others..I just ignored it...Yesterday, I was in 5th gear and I lost all power. engine still running but now power when I press on the gas. I managed to pull over, turn off the car and it acted fine. It happened again on the way home from work. Now the light is off and it seems fine.

So i recently upgraded to a apr k04 from a apr stage2 tune and I'm getting a P0101 CEL. I've triple checked all my piping, and sensors, everything is nice and tight. I did however install the turbo with a GFB DV+ using the spring. Do you guys think the fact that the spring in the DV+ holds an amount air in the intercooler that it's throwing off the readings with the MAP and causing that CEL? I was going to give it a week or so and maybe see if the ECU can adjust itself enough to the DV+ and hopefully solve the problem. If not then i guess ill check for more leaks, but i doubt there is any. Boost holds real good throughout the whole rpm range...
