Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
All right. So a Nissan has a check engine light on and it's running really rough. We're going to check for the diagnostic code that we're getting on this Nissan Ultima using the scan tool. We're getting a P0102, and it says MAF or VAF check low input. We're going to check the mass airflow meter. Make sure it's plugged in fully, and if it's not plugged in fully, we'll plug it in. If it's plugged in fully, we're going to replace it and see if that clears the code.
We're over here at the mass airflow sensor. It goes right in here in the intake tube after the air filter. Double checking the plug is in there and locked in place. As far as these wires go right here at the connector, where they kind of bend. They don't appear to be broken, so we're going to try and replace this mass airflow sensor.
To replace the mass airflow meter, that's this piece right here. Push the lock in, pull the connector off and set it aside. Our replacement comes with a matching security torques bit that fits right in there. It's a quarter-inch drive. To put the top on, I can use this quarter-inch drive tool. Just unscrew it. The other screw is on the opposite side here on the bottom. It's kind of tight to get the quarter-inch driver in there or a socket ratchet, so I'm just going to use a small quarter-inch wrench. Just going to put it in here. We just need to move it this way. Hold it with one finger, and like that. Once it's loose enough, I can just turn it with my hands. Grab the screw so I don't drop it. Pull the old mass air meter out.
Here's our original one from our vehicle and our brand new one from 1AAuto.com. This actually comes with two new screws, security torques, and the bit to install and remove them. Once you put in the car, it'll work great for you. On our sensor, it's got a tab here and a tab here on the intake tube that match up with these openings here and here, so you can only install it one way. Definitely doesn't fit that way, so I'll have to go in this way. Fits nice and even.
Install the screws. Take our supply torques bit, and you continue to just turn it with my fingers. Wrench till you feel it get tight. I'm just going to stop because it's just a metal screw going into a metal bushing that's inside this plastic. We don't want to strip it. Could use the let driver, top one. Reconnect it so it clicks. Mass air meter has been replaced. Now our check engine light is off.

Mass airflow meter is located here, on top of the intake tube, aft of the air filter. To change it, I'll push in on this connector to unlock it. Lift it off, push that down.
There's a screw here and a screw here. It's a six millimeter, or it's a very small Phillips head, you can put in there. I'm going to use the six millimeter ratchet and remove it. Carefully take this one out and don’t lose the screw. Now, on the opposite corner is the other screw.
This is loose. The mass airflow sensor will come right out, straight out.
This is the mass airflow meter sensor. It is keyed on both sides and there's little pins that match on the air intake tube. It only goes in one way. So, this is the correct way. It will sit down nice and even. The screw holes line up. The tabs line up. The lock for the electrical connector’s towards the top. If you tried to put it in backwards, flip it over here, it's not going to fit right. It's close, but it's not quite there. It doesn't really want to line up with the tab. The screw hole doesn't line up. So, if you tried to struggle with this and force it, you could break it. It definitely, when it fits the right way, goes in real easily. You can also tell, there's a direction of flow, so the air is coming from the air filter. It's going into the engine, so it needs to go into this opening and that's how it reads the amount of air going into the engine. It's going to sit in, just like this.
I'll reinstall those screws. These are just really small screws. They're not going to take a lot of torque. I'll get this back one set up. They’re just little machine screws, little insrets in the air tube. You don't want to over tighten them. Get them in there with my fingers. I'm going to take the ratchet and just very lightly tighten them. Right where I feel them get tight, I'm just going to stop.
With those tightened up, I can put the connector back on. It'll click when it locks in place.
