My car started throwing a code[327] over the weekend and running very weak. The code said it was low voltage to the front knock sensor. Can anyone tell me what might be causing this code.Car seems to run ok but just weak at WOT. Any help would be appreciated.

check the load on the power wire to the sensor, your pcm is probably running richer at topend because its thrown itself in a type of "safe mode"

 

any other opinions?
