Attention! Avoid swapping plug connectors (ShSov) knock sensors. This will result in engine failure. Carry out their color or digital marking.
Replacing the right knock sensors
Replacing right knock sensors (cylinders 1–4) must be done in the following order. Read fault information from memory device (memory) ECU-ECU system «DME», switch off the ignition and remove the intake manifold.
Remove bolts (arrows, fig. 4.131) and remove the knock sensors for cylinder group 1-4.
When installing the sensors, clean the contact surface under the knock sensors on the cylinder block. Install the knock sensors and tighten the mounting bolts to a torque of 20 Nm (2.0 kgf·m).
Upon completion of the replacement of the knock sensor, it is necessary to read information about malfunctions from the memory of the memory of the ECU-KSUD of the -DME system». Troubleshoot and erase information from the memory memory.
Replacing the left knock sensors
Replacing left knock sensors (cylinders 5–8) must be carried out in a similar manner, only in this case it is necessary to remove the coolant manifold and pipeline from the coolant pump. Remove bolts (arrows, fig. 4.132) and remove the knock sensors of cylinder group 5-8.
