In this video we're going to show you how to replace the air flow meter, or mass air flow sensor, in this '99 Chevy Venture, same as most of the '98 to '05 Venture or Montana. This has the 3400 series engine in it, also the same as a Silhouette. The only tool you'll need is a flat-blade screwdriver.
Your mass air flow sensor on this vehicle is right here. It is on the driver's side. There's your radiator fill. Obviously, there's your engine, and here's your intake box, and then the tube. There's two clamps, one here, and one over here. You want to loosen those up. This is your electrical connection. Just use your thumb to pull that off and remove it. I'll speed it up here while I just loosen up those two hose clamps.
Once you have those clamps loosened up, you can just grab this big accordion hose and twist it, and then pull it off, and then the same thing with your sensor. Sometimes, actually, it's better to pull it off the plastic box first, then pull it up and out. This part here will go on your new sensor, so gently, you need to break it loose. Maybe use your screwdriver a little bit. This is your old sensor. Here's the new unit from 1A Auto, and actually, ours sometimes come as rebuilt, which is actually a new sensor. This is the plastic, this is actually the sensor part, and then the housing has been refinished. It goes in like that.
When you go to install it, you can see there's a tab right down here. So you want to line that up there, and then put it into a tab here, which lines up with this tab. Life this up, push the sensor in, and push it down and in, and bring it against the box here. Just make sure you squish it all together, and then tighten up your clamps. Plug your lead back in. Then you're all set.
We hope this helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

I put this in my 1996 Chevy s10 pickup 4.3L Vin X Model truck due to my truck shuddering. Installation was easy enough only took 10mins tops. Over all no complaints.

This was a perfect fit and very easy to install for my 2003 Buick Rendezvous. I will be ordering more parts for my vehicle from 1aauto. The bonus is that they had videos to show you how to remove/install parts!
New MAF made a huge difference.

My car was running rough and throwing a code indicating a MAF sensor error. I always try to go to 1A Auto because they have great prices and I have benefitted a lot from their YouTube videos. The new MAF makes a huge difference. Car idles as smooth as silk.

Changed the MAF sensor even though the old one looked fine. Instantly noticed smoother idle, easier start and better performance and gas mileage. Awesome price is just icing on the cake. Super pleased.

Good price came fast and fit perfectly. Have to take a star for the packaging was a bit on the light side. Not much bubble wrap around the item. Was slightly concerned. But the item seems to work fine.
Works for me.

I was worried about buying and aftermarket throttle body and was told that it would have to be programmed to my vehicle and it wouldnt last...I havent had a single problem with it. My Jeep runs like new, I didnt have to get it programmed, and it wasnt difficult to replace. But Ill never buy another FCA vehicle again.

The part came quickly and in great shape. After installing, my car's intermittent hiccup problem was alleviated. The video was absolutely crucial and I wouldn't have been able to install myself without the instructions.

How do I reset the vehicle computer after replacing the mass airflow sensor. HOW ???February 24, 2017

Et a scanner and reset the computer

I have a OBDII code reader and after replacing the Mass air flow sensor I cleared all codes and have not had any codes since. If you do not have a code reader then you can disconnect the positive terminal of the battery for at least 5 minutes and that will also reset all codes. Good Luck - Larry

I would recommend clearing the code with an OBDII scanner, then install the new MAF sensor.

You have 2 options, you can do a soft reset by plugging in a OBD-II sensor and resetting the ECU or you can unplug the battery for 10-15 mins, plug it back up and drive it for 50-60 miles straight so that all the sensors reset and it reads everything like it should... the latter is usually recommended for parts that deal with emissions...
