Sensor Inspection

  1. Disconnect the knock sensor connector.
  2. Measure the resistance between terminals 2 and 3.

    Standard value: about 5MΩ [at 20°C(68°F)] 

  3. If the resistance is zero, replace the knock sensor.

    Knock sensor:  

    16 ~ 25Nm (160 ~ 250 kg.cm, 11.8~18.4 lb.ft)

  4. Measure the capacitance between the terminal 2 and 3.

    Standard value  : 800 ~ 1600 pF
