    knocking noises are rarely good, best possible problem would be a bad knock sensor, next step check to see if your have oil pressure, if no oil pressure then you most likely have a bad rod bearing you would the remove the oil pan and gently tap on bearings to confirm one is loose

    Have a MECHANIC listen to it!! What ever engine it is! 2.2? 4.3? Seasoned tech. can tell you what it is and prob. what you dont want to hear.
    It's not a sensor.

    Agree with wetry- this is not knock sensor. Don't drive vehicle- qualified mechanic will know what is once started!
