How to replace the knock sensor for Bank 2 on Buick Rendezvous?

Begin sensor replacement for Bank 2 by raising and supporting the vehicle first. Disconnect and remove the left knock sensor from its harness electrical connector. Apply thread sealant to the sensor threads because factory coats protect the sensor but additional sealant can interfere with the sensor's detonation detection. Use 25 N.m (18 lb ft) torque when fastening the knock sensor into position. Dual hand steps allow technicians to lower the vehicle. They should reconnect the engine harness electrical connector to the left knock sensor before completing the procedure.
