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?

Passat (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.)

Volkswagen :: Dirty Mass Airflow Sensor Symptoms Detected

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?

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.

Buick - 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.

Sonata NF (2006-10) :: Removing And Cleaning Mass Air Flow Sensor

2006 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.

Silverado :: Check Engine Light Came On - Mass Air Flow Sensor

Ok 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.

Passat (B5) :: Check Engine Light On / Code 16486 - Mass Air Flow Sensor Circuit Low Input

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??

Sonata NF (2006-10) :: Camshaft Position Sensor Error - Check Engine Light On

06 sonata 3.3 L V6. Light has been on for a month or two...took it in to mechanic yesterday and it's a camshaft position sensor error...it makes total sense to me now because my cars been starting hard, seems like it gets hotter then usual...and had a "clicking" noise for about 10 mins, then gradually goes away. it takes a few extra cranks now to start the engine unless it was already fired up.

Also does a jerk once and a while around 40 km/h. I looked online and those seem to all be symptoms of a failed camshaft position sensor (CMP). Would those symptoms seem about right? Am I okay to drive slowly for the weekend before I get the new sensor installed? The mechanic didn't seem to worries about me driving for just the weekend...but it's worrying me a bit...

Ford 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.

Mazda3 :: 2009 - Check Engine Light / PO101 Error Code For Mass Air Flow

My check engine light keeps coming on sporadically and giving me a PO101 error code...then I'll reset it after making sure my MPG hasn't dipped a significant amount (which is my "concrete" way of gauging if it's performance is impaired) and it'll come on 1-600 miles later. There's no consistency in environment or conditions that are triggering this sensor, at least it's not obvious to me. I finally looked under the hood at the filter and it's a little dirty, but not nearly dark enough for it to be the problem.

Lexus GS 2006-11 :: Check Engine / VSC Lights On - P0333 Knock Sensor Code

I just purchased a 2006 GS300 AWD w/115k. Started car on lunch hour to find check engine / check VSC lights on. Ran codes to find P0333 Knock Sensor code. Vehicle seem to run perfectly fine, but now that the light is on, it is definity spark knocking under acceleration. This is my first Lexus / Toyota product, so I am unfamiliar with the common problems or fixes. Are knock sensor replacements common?

Camry :: 2006 - Check Engine Light Came On - Code P0032 For Upstream O2 Sensor

This issue pertains to a 2006 Camry LE 4-cyl.

My check engine light came on - code P0032 (upstream O2 sensor). I bought a new sensor from O'Reilly Auto Parts. After installing the new sensor, the car would jerk while accelerating. This continued to happen until roughly 30 miles or so when the engine light came back on and the jerking stopped! I re-scanned the car and it showed the same error - P0032. I then erased the code, and the jerking issue resumed.

I assumed this was caused by a faulty O2 sensor. I returned and got another one. Same issue.

Is this the result of not getting an OEM sensor from the dealer? Or is there something else I should be worried about?

Sonata NF (2006-10) :: Engine Knock And Check Engine Light Came On

I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.

It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.

I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?
