This description is a bit diffuse. Try
Code:
awk -v COL=$ColumnNo -v SRCH="$PPK" -v REP="$NPK" '
        {FS=OFS="\""; $0=$0                                     # recalculate fields based on " delimiter
         for (i=2; i<=NF; i+=2) gsub (SEP,"\001", $i)           # replace , in " delimited fields with a token
         FS=OFS=SEP; $0=$0                                      # recalculate fields based on , delimiter

         sub (SRCH, REP, $COL)                                  # do whatever you need 

         gsub ("\001", SEP)                                     # just before printing anything, put back the inner ","
        }
1 
' SEP="," file

This is untested as a sample is missing.
