when can i detect the position of error in hamming code

I have 4-bit data with the hamming code 0010011.
the parity parameters are: p1=0 , p2=0 , p3=0
and the check codes are: c1 = 0 , c2 = 1 , c3 = 0
so I thought that I have an error in position 2 of my data but the solution says that I can not detect the position of the error.
my question is: when I can find the position of an error in hamming code?

• okay , I think the solution was wrong – hossein hayati Apr 23 at 9:56
