REMOVAL
Numbers in text in parenthesis correspond to numbered components in image.

1. Remove the resonance chamber.
2. Remove the cable from the retaining clips.

Bank 2 Knock Sensor:





3. Disconnect the wiring harness (1) for the Knock Sensor (2).
4. Securely attach a scrap piece of wire about 36 inches long to the Knock Sensor pigtail. Later, this will be used as a pull wire to guide the new sensor pigtail back through the same routing.
5. Loosen the three fastening bolts for the power steering pump pulley to the power steering pump.
6. Mark the running direction of the accessory drive belt.

Accessory Drive Belt:





7. Release the accessory drive belt by moving the belt tension roller in the direction of the arrow (clockwise), and remove the belt.
8. Remove the power steering pump pulley.
9. If present, remove the lower engine compartment cover, and the fastening bolts for the front left vibration damper from the front axle body bracket.

Motor Mount Engine Bracket:





10. Remove the lower nut (1) from the engine damping block. [Motor Mount Engine Bracket (2)].

Engine Bracket:





11. Loosen the four fastening bolts for the engine bracket (1) a few turns.

Notice: Do not jack up the transmission by the pan. Use a suitable lifting point in order to prevent damage to the components.

Lifting Transmission:





12. Using a hydraulic jack and a suitable adaptor, lift the transmission carefully until pin comes out of bracket.
13. Remove all four fastening bolts (1) for the engine bracket.
14. Remove the engine bracket with the engine damping block.
15. Remove the Knock Sensor cable. Observe the cable routing. Gently pull the Knock Sensor pigtail through the wiring conduit and out. Stop when the pull wire is free of the conduit at both ends.
16. Detach the Knock Sensor from the pull wire, leaving the pull wire in place.

INSTALLATION
1. Thoroughly clean the mating surfaces of the Knock Sensor and the engine block. The entire contact surface of the knock sensor must lie directly on the engine block.

Important: Do not use any washers, any spring washers, or any toothed washers when installing the Knock Sensor. Tighten all of the fasteners to the proper torque.

2. Install the Knock Sensor to the engine block.
3. Securely fasten the Knock Sensor pigtail to the pull wire that was left in place during the removal procedure.
4. Use the pull wire in order to guide the Knock Sensor pigtail back through the proper route, out to the retaining clip at the power steering pump.
5. Remove the pull wire.

Important: When routing the cable for the Knock Sensor, ensure that the cable does not contact the exhaust manifold or any moving parts (e.g. accessory drive belt).

6. Connect the wiring harness to the Knock Sensor.
7. Fasten the harness to the retaining clips. 8. Install the pulley onto the power steering pump. Then, tighten the fastening bolts.
9. Rotate the belt tension roller in the direction of the arrow (clockwise).

Important: Make sure that the accessory drive belt routing and running direction are correct.

10. Install the accessory drive belt. Release the belt tension roller. The accessory drive belt tension is automatically adjusted by the tension roller.

11. Install the resonance chamber.
12. Loosen the upper fastening nut for the engine damping block until the engine damping block can be moved in the engine bracket.
13. Install the engine bracket with the engine damping block. Install/tighten the four fastening bolts.
14. Lower the transmission carefully until the guide pin and the fastening stud sit correctly in the front axle body bracket.
15. Install/tighten the lower fastening nut for the engine damping block.
16. Install/tighten the fastening bolts for the front left vibration damper.
17. Install the lower engine compartment cover, if so equipped.
