This is the Vantage set up with the proper cables to do the job.
 

The Start...

The first step in any test done on the Vantage, is to
select the make of the vehicle.  In this case it was a
Ford.
 

The next thing you have to do is choose the Electronic
Engine Control (EEC) system.  In my situation, I was
working with an EEC-IV.
 

Now you have to choose the right option for the test
you want to perform.  And since I am working on
EGR, I go into the component tests.
 

Here we have the EVP sensor high lighted.  This
sensor is strictly on Fords.
 

This is the screen that should pop up next.  The line
running across the graph shows the volts compared
to seconds being run through the sensor.  The line
runs straight across because without the vehicle
turned on, there is no power running through the
system.
 

Now it's time to find out where you connect the wires
to get the right readings.  So you go to the connector
option.
 

In this test you have to connect the red lead to the
EVP signal wire (number 4) and the black lead to a
ground.  You have to do this before you will get a
reading.
 

Now that you found the EVP signal wire, you take the
clamp and push bed of nails section through the wire
coating.  This causes no damage to the wire.
 

For this you can use any common ground, I used the
center stud on the carburetor.
 

How It Works...

This is the reading I got when I first got power
to the sensor.  When you apply vacuum the
graph should shift up and down when the
vacuum is released.
 

This is an example of how the graph would
look when vacuum is applied.  It wouldn't
go up in steps but, I applied vacuum with
a hand pump.
 

This is how the graph looks when the vacuum
is released.  It is a steady drop.

-In the tests option, you will be given a set of numbers that refer to the voltage.  These numbers
represent where the voltage level should be when the EGR is fully closed and fully open.
In this case the reading was 1.22 VDC.  This tells you that the EGR valve is not closing all
the way.  The specified voltage was between .4 to .6.  So we removed and cleaned the EGR
until to desired voltage was met but, if you can't get to the right voltage level, the EGR should
be replaced.
