    Q:
    Where are the Knock Sensors located and How to their removal and installation on Chevrolet Malibu? Posted by Dewon W.
    A:
    The knock sensors are located on the back side of the engine block. Begin by raising the front of the vehicle and securely supporting it on jackstands. For 2015 and earlier 2.0L and 2.5L engines, remove the secondary air injection pump. For 2016 and later 2.0L models, access the rear sensor by removing the starter. Locate and disconnect the electrical connector from the knock sensor, then remove the retaining bolt and take out the sensor. Installation is the reverse of removal, ensuring to tighten the retaining bolt to the specified torque.
