How to Replace EGR Pressure Feedback Sensor 2000-02 Ford Focus

Hey, friends. It's Len here, at 1A Auto. Today I'm working on a 2001 Ford Focus, and I want to show you how to replace an EGR pressure feedback sensor. It's going to be a very easy job. I want to be the guy that shows you how to do it. If you need this or any other part, you can always check us out at 1aauto.com. Thanks.

First thing we're going to do is we're just going to take apart this air filter housing right here. Just come under here, we got a little clamp. You can you use a flat blade screwdriver. There we are. Grab this. This is your mass airflow sensor right here. It's the wiring for it. You just squeeze it with your thumb. Give it a little twist and pull. Take a look. Make sure you don't see any funny colors in there. This looks great. We'll set it aside. You can either take this off—there's a little clamp right here. Take the hose off of there, or if it's easier for you, essentially all you need to do is just pull this straight up—this one right here. Here we are. On the back side, there's a hose here. Let's get it off. I'll show you. Here it is. Okay. This just goes right in here. Set this aside. You can take this. Set it aside, so it's safe.

So right here is the sensor we're replacing. What we want to do is squeeze this little tab. It doesn't squeeze very much, so I'm going to grab a pocket screwdriver, come right in along here, lift up right there, pull that off. Check our electrical connector—it looks great. Set that aside. Okay. This right here, you just want to remember that the electrical connector faced to the rear of the vehicle. I'm going to take my same pocket screwdriver, I'm going to come along the bottom side here, try to find where the hose connects into it, just pry. Do the same thing for the other side there. Okay. So there's that. That was bound to happen. No big deal. We'll get that piece out of there. It's just a little hose. We can pull the whole hose off right here. Just need to break it free. It's been on there probably since the car has been around, so a long time at this point.

Okay. It's not coming up very easy, so I'll just dig this way. Just going to stick my small screwdriver in there, try to weasel it around just like that. Grab a little splash of penetrant, just work it around. Penetrant's going to get in there, do its job, act as a lubricant. And I'm just going to lift this right up out of here. There we are. Grab that piece. There it is. Didn't go anywhere far.

We've got our new sensor. Just do a quick product comparison for you. Here's our two sensors. As you can tell, they're both the exact same. There's a little nub that's supposed to be there. You can imagine it's still there if you want. Same electrical connector, same backside—really not much to it. We'll set that aside. Grab our new sensor, bring it over. If you wanted to, you could put a little bit of a lubricant, penetrant—whatever you want to do. Let's put a little bit on my fingers here.

I'm just going to help slide it in. Try doing both at the same time, just like that. Alright. Grab our penetrant so it's not falling down. Grab our wiring, bring it down and under here. We're going to listen for our click. No, I didn't hear the click, but I can see it. It's locked right in right there. Give it a little tug. Feels good. It's not going anywhere. Perfect.

Get this back down here, just like that. We'll grab our air filter box. This should slide right down. You've got little rubber bushings here—one, two, three. Theoretically, there should be little nubs on the bottom of this. This is an old box. It's probably been off a bunch of times. It doesn't look like it's in the best of condition. We're going to slide this down. You want to make sure you grab this hose. Might be easier for you to put on at this point before you get it all the way down. Just going to slide it right on there, hopefully. There we go. It's on.

We're going to slide those in so those three pins are locked into their rubbers. This one doesn't have the pins, so there isn't anything I can do about that. Push this down. We'll tighten that up so we don't forget. Flat blade screwdriver.

Okay. Come back over to the other side—mass airflow sensor. There you are, clear to start up the vehicle and test it out.
