Hey, 

 Do you have a air temp sensor in the IC??? I have an 865ktq that the 
wires to the sensor broke off and I got the same reading. Just at the 
point of boost or abouts there it would show the engine knock light. 
Resoldered the wires and it went away.     

The sensor is on the pass. side next to the IC hose to the intake.
  Good luck.!!!
