In this case, the adjustment of the ignition and the knock sensor is carried out via the memory of the diagnostic system. There are no other control options. Sometimes a faulty knock sensor gives off a frequent engine chirp when accelerating.
When installing a new sensor, be sure to pay attention to the correct tightening torque of the mounting bolt (15-25 Nm).
Some models have two knock sensors. The figure shows the left sensor (2) with mounting bolt (1). The tightening torque of this bolt must be observed, otherwise the knock sensor will not work.
