Ignition systems / Knock sensor - removal and refitting

Note: This sensor is fitted to the G40 model (engine code PY) only.

Removal
1 The knock sensor is located on the rear of the cylinder block, below the inlet manifold.

2 Ensure the ignition is off, then unplug the wiring from the sensor at the connector.

3 Slacken and withdraw the mounting bolt and lift off the sensor.

Refitting
4 Refitting is a reversal of removal, but note that the sensor’s operation will be affected if its mounting bolt is not tightened to the correct torque.
