    Q:
    How do you replace the Knock Sensors for the 2006 Dodge Durango? Posted by Waylon B.
    A:
    To replace them, start by disconnecting the cable from the negative battery terminal. Then, disconnect the knock sensor electrical connector, which is located at the rear of the engine, behind the intake manifold. Remove the intake manifold and then remove the knock sensor assembly by taking out the mounting bolts. Make sure to clean the holes for the mounting bolts before installing the new knock sensor assembly. Note that the left knock sensor is identified by an identification tag and has a larger mounting bolt, so do not switch the knock sensors.
