First measures of rack position sensor.

Using a audio PC-Scope, I measured several wires at the ECU.

The signals has the shape shown in the graphs bellow.

First: blue wire at 700 rpm (idle) (Rack position)
Second: same at 1500 rpm (approx)
Third: Green/yellow wire at 700 rpm (RPM)
Fourth: Black/yellow wire at 700 rpm (Rack position)
Fifth: same at 1500 rpm.

The table shows the color of wires attached to the ECU.

I am working this subject with the help of AndrzejM who is working the Microcontroller circuit that will process the signals.
