Hi, I'm Don 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 are going to show you how to replace the mass air flow sensor on this 2003 Nissan Altima with the 2.5 liter four cylinder engine. The only items you'll need for this are a new mass air flow sensor from 1AAuto.com and a 10mm socket and ratchet.

Start off by just loosening this clamp using a 10mm socket and ratchet. Now, flip the tabs on your air intake box lid and just pull the lid forward and up and out of that air intake hose and then push the tab on the mass air flow harness and just pull that off. Now, to separate the mass air flow sensor from the lid, you want to remove this four 10mm bolts by using a 10mm socket and ratchet, or using a Philips head screwdriver.

Now, you can see the old mass air flow sensor on the left, and the new on the right. They are identical. They will mount the same and work exactly the same. You want to just line up your mass air flow sensor and first just put each bolt in by hand and then tighten them up with the socket and ratchet, and we'll just fast forward as Don does this. To reinstall, put the air box top and mass air flow sensor back in. Start the flow sensor into the hose. Then, there are tabs on the top of the air box that go into slots. Slide those in and then push it down and reengage the clips, reconnect your mass air flow sensor, make sure the hose is on there securely, and tighten up the hose clamp, and you should be all set.
