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.
View 9 RepliesFord - Taurus :: 2005 - Can Cleaning A Mass Air Flow Decrease Mileage?
I had a check engine light on my 2005 Ford Taurus and my mechanic suggested cleaning the mass air flow. Afterwards, the light was off and the car seemed to drive fine ( it was driving fine even with the check engine light on) But my mileage dropped drastically. On the freeway it went all the way down to 10mpg! Right now around town it is fluctuating a bit, but around 14mpg. Should I have the mechanic check for a loose wire or something not connected properly? Or just replace the darn mass air flow?
View 9 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.
Prius (2004-09) :: High Idle After Cleaning Throttle Body

Few weeks ago.....Prius was showing the P0505 code .... Mechanic, ran diagnostics and determined it was dirty TB. Cleaned TB.....cleared the code (inspected PCV...hoses).
When I initially picked it up it was revving very high....so he hooked it back up to the scanner and did some type of "reset" for the idle (this cleared most some computer settings...back-up beep, radio stations, etc...). Everything ran fine for past 3 weeks...
Just last night..... started running rough again. What I noticed this morning ... Started it up and it ran very rough til the auto shutdown after warmup (no warning lights). Then....when I started driving slowly out of the lot...it ran "rough upon acceleration"...... Then fine at cruising speed. Same behavior at every light....rough acceleration.... fine once up to speed. Just started it up again and same behavior.....(does not die...just very rough).

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.
View 5 RepliesCamry :: Mileage Changes After Cleaning Throttle Body
I cleaned my throttle body this afternoon.
My car started fairly easily, and I continued with running it to 4k RPM a few times, then took it for a ride. I floored it a few times, as suggested, to clear everything out.
Now, my 2004 J-VIN Camry is running around 1200 RPM, it was at about 650-675 before the cleaning. Is this normal? Do I need to d/c the battery to reset the ECU so the car can re-learn with a clean TB?

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.

I decided to take out the throttle body and clean it with throttle body cleaner that I got from autozone, after I put everything back, I started my car and the motor was shaking and smoking a lot out the muffler and just would not be drivable at all. the RPM was just going up and down and hesitating bad. later I took off the spark plugs and they were very much burnt black at the tips and that is probably not normal right? but I replaced them with NGK BKR7E spark plugs and it still gave me the problem.

Any pics addressing where is it, what makes it dirty, how to open it, what to clean it with and how often as preventive maintenance?

I want to replace my MAF and the wiring that leads to it.
