Just throwing it out there, there is a correction to the 2003-2005 manual that swaps the codes listed in the book, thus making a 26 the left and a 25 the right. I was getting a 25 for awhile too, but since the fuel pump issue was fixed, I haven't had it come back on. Bought two knock sensors just in case I needed to swap one or both, but so far they remain on the shelf. Never have touched the ECU.
YMMV.
