2003 Lexus GS300 Mass Air Flow Sensor DIY Solutions EMS00612

Hi, I'm Mike from 1A Auto. We've been installing auto parts for over 30 years.

Hi, everyone. Sue here at 1A Auto. Today we're going to show you on our old 3 Volvo V78, 2.4 liter how to take the MAF's air filter sensor out. It's located in the top of the air filter box. And the mounting screws are just two Phillips heads. So we'll take a Phillips screwdriver. Push down. Let's take that bolt out. And the other one. Real small, make sure you set them aside. And then you can grab this sensor and twist it. Pull up. It's mounted with an O-ring. Now we see the connector. Push down on that tab, and slide it out. If it gets stuck you might need a flat head screwdriver. There we go. Well here's the MAF's airflow sensor.

I'm ready to connect the connector again. I'm making sure there's no damage and that the prongs are all straight. Connect it. Line up and snap it together. Now I can drop it down in the air box. Just wiggle it slightly back and forth so the O-ring sits. And I'll just get my mounting screws. The little small Phillips heads. Snug it down. Maybe make sure it's nice and air tight. It has to be tight. Then you're ready to go.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Hi, my name's Sue from 1Aauto.com, and today we're going to be putting a mass airflow sensor in an 07 Mazda 6 Sedan 2.3-liter. To start, we're going to open the hood, and that's the lever mounted on the driver-side knee panel that has a picture of the hood. Pull on the cable, and then go out and release the safety latch.

So now I'm going to release the hood safety latch that's mounted right above the symbol of the car. Bring it over to the driver's side. Lift up the hood. The hood prop rod is right here in the front. It goes right into the slot that's marked with an arrow. So to replace the mass airflow sensor, we're going to disconnect the sensor itself first, from the harness and it's a push tab, push down on it, and squeeze it out.

I like to make sure there's no burnt connectors that can cause a code or running condition also. Now we have two mounting screws. You just need a Phillips screwdriver. I'm going to dismount them. You just give it a firm twist and lift up. There's an O-ring right here, that keeps it nice and sealed.

Here we have a mass airflow sensor from 1aauto.com, and the factory sensor I just took out of my Mazda 6 2007. They look like they're from the same manufacturer.

So then we have our new mass airflow sensor, has a new O-ring, as you can see it's not crushed like the other one was.

So I'm just going to place that right in here. I wouldn't put any silicone or lubricant on this, because on a mass airflow sensor that is part of the reader right there. That's the air temp sensor on it, and the mass airflow sensor is inside. They pick up on dirt or oil, and it throws the sensor off, the reading, so a nice dry seal's fine because it's plastic, it's not metal.

So I'm just going to mount it down. You cannot mount it the wrong way as you can see. If I went like this, the holes don't line up, it's nice and easy, self-explanatory, press down. I felt it move right in. Now I'm going to remount it with the two Phillips head screws. I'm not going to snug that down tight yet until both are in. Now I'm going to reinstall the connector. Make sure that that orange seal is still on there. That's the moisture barrier, water seal. And I'm just going to wind it right up, click it on. There you go, now you're ready to go.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part 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 2002 Volvo V70 with the 2.4-liter non-turbo engine. The items you'll need for this is a flat blade screwdriver, a Phillips screwdriver, and a 10mm socket and ratchet.

Your mass air flow sensor is located right here. Just push down on the tab and disconnect the harness. You may need to pry out a little bit if it hasn't been removed in a long time. Now loosen up this hose clamp and pull the intake hose back. Now flip up these clips, pull them back, and pry these hoses free. Then the top of your air intake box will lift up and off.

Next, remove these two 10mm bolts. If your new mass air flow sensor doesn't come with the housing then remove the sensor with a Phillips screwdriver, and then remove these two bolts. Then the sensor just pulls out.

Then you'd push it into your new housing and replace those two Phillips screws. Push your new mass air flow sensor back into the top of your air intake box and replace those two 10mm bolts. Now push the tabs on the top of the air intake box back into those slots and push it down into place. Re-clip those three clips. Then reconnect these two hoses on the back. Push the intake hose back into place and tighten up that hose clamp. Then reconnect your mass air flow sensor harness. You're all set.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Hey everyone, Sue here at 1A Auto. Today on our ‘03 Tundra, we're going to teach you how to remove and replace your mass air flow sensor. If you need this part or any other part for your car, click on the link below and head on over to 1aauto.com.

Hood release on this Tundra is located on the driver's side, right at the knee panel. Has a picture of the hood, pull on the cable. So the safety latch is located to the left of the symbol. You'll feel the lever right there. You push up on it. Lift your hood up.

This is the mass air flow sensor location. It's on top of the air box cover. So to change that, I would loosen the harness out of the connector here. You've got the tab, push tab, push down on that and slide her out. It's been a while since this has been out. So squeeze firmly and wiggle. Or not. There you go.

I was careful not to break that tab. You never want to break the lock tab if possible. Phillips screwdriver, these two mounting bolts. And then you're just going to grab it and pull it up. There is an O ring here. Make sure that's not broken. Seals not broken. And that's actually the pieces that take the reading of the air flow and the temperature.

To replace it, you just place it, line it back up, and press down firmly so that O-ring seats. Put each screw in. I'm just going to bottom that out. I'm not going to tighten it until the other one's in. Now it's safe to reconnect our connector. Hear that click, line up the harness, and you're done.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Hey everyone, Sue here at 1A Auto. We've got a '07 Mazda 3 with a 2.0 liter in it, and we're going to show you today how to remove the mass air flow sensor, examine it, and reinstall it. If you need any parts for your car, head on over to 1AAuto.com.

Hood release is located right here. Safety latch is right above the Mazda symbol, right in the center. Just turn it over to the right, and then you have the hood prop rod, and you put it in where the arrow goes and says rod. Right in there and lock it in.

I'm going to remove these three clips. This one will might just be a pull up. It's a body clip. There we go. These plastic clips are just like a little Phillips. Just pull them up a little bit and I can wedge them out with a screwdriver. Set that aside.

Now we're going to remove this right here. Take the cover. Start by removing the tab, and that is a tab that you push down on the back here. You can see the arms push-up and pull on it. Then we have two mounting screws. They're Phillips heads. Just take a Phillips screwdriver and pull that one out. Grab it and twist it. Pull it up. There we have our mass air flow sensor.

To reinstall the mass air flow sensor, reverse the procedure. Make sure there's no dirt or grime in there. Make sure the O-ring is still connected and sealed around. Place it down, and you'll feel it push and grab. Install the two mounting screws. Just a snug down. They're plastic housing. You don't want to strip that. Snug it.

Examine the connector and make sure everything's still there. All the connectors, there's none melted, there's no debris in there, and no oil soaked. Line it up. Push it 'til it clicks. This goes underneath the air box, well first it goes down this way, sorry. Let's see what's happening here. There we go.

So line this plastic piece up. It's got the V shape in it. You're going to line it right up with that indent plastic, and then this side will go inside the battery box on top of the air cover. Then we have the plastic cover over here. There you go.

Hey friends, it's Len here at 1A Auto. Today, we're working on our 2011 Mazda three and I want to show you how to replace a mass airflow sensor. If you need this or any other part, you can always check us out at 1aauto.com. Thanks.

Okay, so right here is our mass airflow sensor. This is what meters the amount of air that's going through into our intake and getting burnt up in our engine with the fuel. So, what I like to do is just try to clean it up a little bit around the area. Doesn't have to be anything too special, but if I can at least get off of the majority of the big chunks that are in the generalized area, I'm doing all right.

With that done, there's a little push right here. I'm just going to squeeze it. Give this a little wiggle. Pops right off. We always check our electrical connectors for any funny colors. Rainbow colors inside of electrical connectors are very bad. You don't want any blues, reds, greens. Well, pretty much anything except for metal color. This one looks great. I'll set it aside. We have two Phillips heads that are holding in the mass airflow sensor, so I'm just going to use this. You can use a regular screwdriver with a Phillips head if you want. That's what one of our screws looks like. Screw number two, the exact same thing as the first. Easy peasy. We'll grab this, give it a little wiggle and it pops right up.

Let's move ahead to the next step. Okay, friends, a quick product comparison for you. Over here we have our original mass airflow sensor out of our 2011 Mazda three and over here we have our brand new quality 1A Auto part. Both these pieces are manufactured the exact same specifications. They're both the exact same shape. They have their metering area in there. That senses how much air is flowing by. We have the electrical connector port. You want to make sure you have the same amount of prongs. This one looks perfect. Coming along the top, you can see we have the same two mounting holes. With all that said, I don't see any reason why this wouldn't be a quality part to install into the vehicle, so I'm going to go ahead and do it. If you need this or any other part, you can always check us out at 1aauto.com. Thanks.

Okay. So, we're going to take our brand new quality 1A Auto part mass airflow sensor. It's going to go right in here. Give it a little push, slides right down into its happy place. We've got our two screws. I'm going to get them both started in here before we tighten either of them down. Just see about getting it started. There we are. This one. Okay. They're both started in. I'll make sure I have this thing turned all the way down here. Here we are.

Okay. What we're doing is we're just screwing into plastic here so you don't want to go super tight, but you do want to make sure that you go tight enough to make a good seal on this. You don't want any air getting sucked in past this and not getting metered, getting sucked into the engine. Not only the fact that it's not going to be metered, but also it's not going to be filtered because the air filter's on the other side of it. Okay. So, we'll grab our electrical connector. We already checked it. It looks great. We're going to slide it in and we're going to listen for a click noise. There it is. Nice and locked. Give it a nice little tug. You can't go anywhere. Close the hood, down the road we go.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Open the hood. We have to pull the release inside the car. It's just inside. Right around your left knee on the driver's side. I need to release the secondary, or safety release. Just kind of feel around for it. This one is right here. Squeeze up.

Mass airflow meter is located here at the back of the air box. To remove it, start by unplugging it, push down on the connector to unlock it, and then wiggle the connector off. Use a Phillips head screwdriver to remove the two screws. Grab the screw, and put it aside so I don't lose it. Do the same for the other one. This should lift right out of the intake tube.

This is the original mass airflow meter from our car, and the brand new one from 1AAuto.com. It has the same style connector and the same style mounting holes. This should fit and work great in our vehicle.

So you can only install it one way because the screw holes aren't going to line up. So line them up like that. Just push it in, and it will go past the rubber O-ring. Use your magnet if you don't have a magnetic screwdriver. Get that in place. These are just self-tapping screws. As soon as I feel them get tight, I'm just going to stop. That's nice and tight. Reconnect the plug. The job is complete.
