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.
We hope this video 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.
Quick service

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...
