Or it was random corruption of the stored PICkit 3 state in the PC memory and rebooting the PC resolved the issue . . . .

We tried prgramming a circuit that has 16F882 and few pheripherals using pickit 3 ( the current drwn by the hardware
is less thand 40 mA. we are getting the mesage " target ID does not match" These are the circuits which was working 
previously and one need to suspect some other hardware problem. The P!C kit worked for other devises and is working well. 
our doubts
1. is the The MCLR/Vpp votage shall be higher while programming 
2. what is the Vpp voltage level?
3. will it be applied by the PICKIT automaticaly while programming.
It will be nice if some one could help. pl send reply to achuthan@presevi.in

1. is the The MCLR/Vpp votage shall be higher while programming

In HV mode, it pulses hgh briefly to enter programming mode.
You can see that on a scope, but not with a meter.
 

2. what is the Vpp voltage level?

About 13V
 

3. will it be applied by the PICKIT automaticaly while programming.

See above. Only briefly.

That's not how forums work. People don't email replies, everything stays in public so others can benefit from the answers.
