thats a knock sensor code. it signals any spark knock and tells the computer what to do w/ the timing( advace/retard) Official repair method: "Check wiring and connectors form the knock sensor to the ESC controller or ECM for an open or short to ground; if necessary, reroute the harness away from other wires suck as spark plugs, etc. Replace the knock sensor"

Suck as sparks plugs huh? 
Heard that one more then once! Hey, could be the ESC module too. Worst case, bad ECM. I'm just quoting the book.
