CHECK HARNESS BETWEEN ECM AND KNOCK SENSOR .
1. Turn the ignition switch to OFF.
2. Disconnect the connector from ECM.
3. Measure the resistance between ECM connectors.
  Connector & terminal
  
  (E158) No. 19 - (E158) No. 6:
  
  Is the resistance 600 kΩ or more?
  
  Yes: Go to 2.
  
  No: Repair the poor contact of ECM connector.
CHECK KNOCK SENSOR .
1. Disconnect the connector from the knock sensor.
2. Measure the resistance between knock sensor terminals.
  Terminal
  
  No. 1 - No. 2:
  
  Is the resistance 600 kΩ or more?
  
  Yes: Replace the knock sensor. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO (HEV))>KNOCK SENSOR .
  
  No: Repair the open circuit in harness between ECM connector and knock sensor connector.
