Knock Sensor: Testing and Inspection

SENSOR INSPECTION
1. Disconnect the knock sensor connector and measure resistance between terminals 1 and 2.

Standard value: about 5 MOhms

2. If the resistance is continuous, replace the knock sensor.

Tightening torque
Knock sensor: 16 - 25 Nm (160 - 240 kg.cm, 11.8 - 18.4 lb.ft)

3. Measure the capacitance between terminals 1 and 2.

Standard value: 800 - 1600 pF
