Knock Sensor: Testing and Inspection

CIRCUIT DIAGRAM








HARNESS INSPECTION PROCEDURE





SENSOR INSPECTION
1. Disconnect the knock sensor connector.
2. Measure resistance between the terminal 2 and 3.
Standard value about 5 M Ohms [at 20 °C (68 °F)]
3. If the resistance is continual, replace the knock sensor.
Tightening torque
Knock Sensor 16 - 28 N - m (160 -250 kg.cm, 11.8 -1 8.4 lb.ft)
4. Measure the capacitance between the terminal 2 & 3.

Standard Value 800-1600 pF
