Answers :

  • Verify the resistance of the knock sensor \012 (compare it to factory specs)
  • Inspect for broken/frayed wires leading to the sensor
  • Check the wiring and connections leading to/from the knock sensor and PCM/ECM
  • Verify proper voltage is reaching the knock sensor (e.g. 5 volts)
  • Verify proper grounding of sensor and circuit
  • Replace the knock sensor
  • Replace the PCM/ECM
I just had this happen to me I have a cam upgrade computer upgrade and rockers with other things and I was looking for this code issue for a few hours and I remembered that it's not just knock sensors but it's also fuel and I started checking the fuel injection and one of my clips on my wire that goes to the injecter had been broken when it was put back together
