Brought you by 1AAuto.com your source for quality replacement parts and the best service on the internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. 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.
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 at 888-844-3393. We are 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...
