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.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the mass air flow sensor on this 2003 Chevy Monte Carlo with a 3.4-liter V6 engine. The items you'll need for this are a new mass air flow sensor from 1AAuto.com and a flat blade screwdriver.

Your mass air flow sensors right here, and on either side of it, there's these two hose clamps. Just loosen both of those up with a flat blade screwdriver. Now, pull your intake hose back and free from the intake box. Then just pull the mass air flow sensor out. Then lift up the tab and disconnect the harness and pull this small hose free.

Take the smaller piece of hose and put that tab in between those two slots as you push it into place.

On the left is the old mass air flow sensor; on the right is the new one from 1A Auto. You can see they're identical and they'll fit exactly the same. Take your new mass air flow sensor, and you wanted it at this angle. You want to just fit it into that larger part of the intake hose first, and that arrow on the mass air flow sensor should be lining up with the mark on the hose. Then just tighten up the hose clamp.

Now push the mass air flow sensor into the smaller part of the hose on the air intake box, and then tighten up that hose clamp. Reconnect the harness and you're all set.

I want to help you save time money repairing and maintaining your vehicle. I'm going to use my twenty plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts, installed correctly. That's going to save you time and money. Thank you and enjoy the video.

In this video we show you how to replace the mass air flow sensor on this Buick Century. Same as many GM front drive vehicles with the 3.1 or 3.8 liter V6s. You're going to remove your intake hose by loosening up this clamp over here at the engine and this clamp here at the air box. Then you pull your hose off the engine and then pull your hose off the air box. That comes up and out of the way. To replace your airflow sensor obviously you unclip it here from the harness. Remove or loosen this clamp here. You can see these arrows line up. You want to make sure those line up when you put it back together. You may want to use some force from the screwdriver to pry the hose off. There's your sensor, out.

You can see I'm putting this old one back in because there's nothing wrong with it. What I'm going to do here is put this collar on the air box first. I'm putting this piece onto the air box to get it nice and secure. You want to make sure that nothing folds over or gets around. Make sure it's on there good. Now, take this sensor and move this hose up here. Put the sensor in. Shake it around just a little bit. My hose, push it down on. Again, you want to line up these two arrows. Tighten up this first clamp. Make sure those arrows are lined up. Plug in my airflow sensor. Tighten up this second clamp. Make sure my air hose is on the engine well and tighten up this third clamp under here.
