How to fix this?
Can circuit designed to solve this problem?

Use external power source...

Well have just tried the pic24 with its own power source and without any power and MPlab still senses the Pickit2 Lite as at 5v.
If there is a way to fooling Mplab into sensing it as 3v3, please help.

Are we talking about the same programmer ?
I know saeidjabbari has used Pickit2 in the title, but he is actually talking about the DIY Pickit2 Lite as featured in this forum, which normally runs at a fixed 5v.
To allow him to program the 3v3 Pic24 you can add a 3v3 regulator to the USB +5v line so the whole 2550 circuit runs at 3v3 so making it ok to program the pic24.
No matter how I power the pic24 or how I change the Mplab PK2 Programmer settings it still sees the diy Pk2 Lite as 5v - unless you know of something else ?
