    I have not gotten a manual yet and she is throwing a knock 2 sensor code. Can anyone help with the location of this? Thank you.

    The Knock Sensor's are Located, Underneath the Intake Manifold, in the Diagram, Number #717 is the Wiring for the Knock Sensor's and Number #718 are the Sensor's.


    Edit....here's an Actual Picture of a Knock Sensor,

    we just talked about this,try not to clean youre engine,water gets under intake and sits,i made the mistake,get 2 k.sensors and the pigtail wire harness,and leave out rear foam insul. under intake to let water out,cant remember specs but torque sensors properly,too tight,too sensitive

    Thanks for your help. Havent changed it yet but seems easy enough. Now the rear end is squeaking quite a bit, figure take her in for a chassis service.
