Caution! Tighten to the correct torque. If the knock sensor is over-tightened it may deform. If it is too loose it may disrupt the function of the sensor.

- Install the new sensors using the screws in the cylinder block
- Route the cables on the outside of the starter motor bracket
- Align the sensor (looking from the front towards the rear)
- The cable from the sensor for cylinder 3 = 3 o'clock and from the sensor for cylinder 5 = 6 o'clock. Tighten the knock sensors. See Tightening torque, B6324S Tightening Torque.
Press the knock sensor (KS) connectors together. Check that the wiring is in the correct position. Use a clamp if necessary.
