Hi, I'm Wade from Thoroughbred Diesel, and today we're going to teach you how to change
your map sensor on your 73 power stroke.
On our 2000 Excursion, while I was doing an installation video not too long ago, I managed
to break the end off of the map sensor.
The map sensor has got a little nipple on it right there, where the air supply line
goes into this, show you that, broke it off, totally my mistake.
We're going to be replacing this map sensor today.
I thought it'd be a good way to do a video because we sell a lot of boost foolers for
the 73 power strokes.
This model map sensor fits the '99 to 2003 model sensory power strokes in the Super Duties
and the Excursions.
I just want to show you today.
I want to show you the location of the map sensor.
I'm going to show you how to change the map sensor, and we'll get a new map sensor on
this one and chalk it up to one of my mistakes.
First off, let's show you where the map sensor is on the 73 power strokes '99 to '03 trucks.
The map sensor is located on the right hand side of the engine, passenger side of the
engine.
It's located on a bracket here.
One way that you can know exactly what the map sensor is, there is an air supply line,
and this was not attached to our map sensor, because like I was telling you, I broke that
off when I was installing an intercooler pipe, but you have an air supply line that will
come from the manifold down here, that supplies over the map sensor, map manifold absolute
pressure sensor.
It has to have something, an airline on it for the turbo.
Now, we are going to go ahead and start swapping out that map sensor.
First thing you're going to want to do is you're going to want to make sure that you've
got your battery cables undone on the truck.
You don't want to have any electrical problems.
T20 Torx and a pair of pliers, and we will go ahead and take that off.
This is a five volt reference sensor.
If you're looking at a wiring, a diagnostic, you just know that it's on five volt reference.
We sell a lot of map sensors.
This is a convenient video for us to do because we sell a lot of boost foolers.
I'm sorry.
This is a convenient video for us to do because just wanted to show you where the map sensor
was on these trucks and so on.
Like I said, T20 Torx, go ahead and take the two screws out of this.
Don't drop them.
It's a really bad place to drop a screw, especially on Excursions because there's a lot of stuff
going on over here.
When you get it undone, you can undo your electrical.
There's a little [catch 00:02:49], just go ahead and unplug it.
Then go ahead and bolt your new one up.
These are tapping screws, so you've got watch this.
When you go to do it, you want to try to get it started as straight as you can and get
a couple of turns on it, if possible because you can kind of get that going in a bad direction
where that's a new cut on that screw.
It'll take whatever path you send it down.
A couple of turns on there and then you're good to go.
Just snug those down.
Don't overdo it.
Before you do your wire, you want to go ahead and do your airline here.
Go ahead on the other side of the map sensor, go ahead and put your airline on.
All right.
Put our cover back on and hook your electrical portion back up.
There you go.
You've installed yourself a new map sensor.
Super easy to do.
Don't be a bone head like me and break the airline off of it when you're putting your
inner cooler pipes on, but it's worth noting.
When you're working around stuff like that, those are the types of things, those are the
$100 mistakes that you can make that are easily avoided and I know better than that.
I hope you enjoyed this video.
If you've got any questions on this again, one thing that this ties into quite a bit,
we sell a lot of boost foolers.
That's where you boost fooler goes, on the map sensor, so that shows you where your map
sensor is at.
