Hello , thanks for your question in the autoaid Community.
Your described fault Code means: KNOCK SENSOR 1 CIRCUIT RANGE/PERFORMANCE BANK 1 OR SINGLE SENSOR
If you´ve changed the knock sensor, you should measure the wirings to this sensor.
Sometimes there was a bite in it from any animal, then i must say that the same wiring complete, means the engine wiring, have to be changed. Because the knock sensor is with wirings connected they are shielded.
Look for the wiring and with the correct wiring diagram measure the wires from the ecu to this sensor.
If you have the sensor screwed to hard, likes more than the maximum of 20nm, the sensor measures wrong.
