Thanks

I appreciate it

Although the servo was modified along time ago for continuous rotation,
Although it still works

5volts is actually low for a servo, that's the lowest amount of voltage you can imply.
In the book I own PIC basic projects
it has a servo page and it states that servos can run from 5vdc to 9vdc and 5volts was not recommended.

I tested it out and it works fine

I believe for it to be the sensor
