KNOCK SENSOR
Functions
Vibration of the engine block is transmitted to the sensor and
transferred to the ECU in the form of an alternating voltage
signal via a shielded cable. The knock sensor is fastened to
the engine block to recognize knocking in all cylinders. The
ECU compares the signal and the retards firing point.
Removal & Installation Procedure
1. Disconnect the knock sensor connector from the intake
manifold bracket.
2. Unscrew the mounting bolt (M8 X 28) from the knock sensor
installed on the cylinder block and remove the knocking
sensor.
