    Hey Dudes, if you have the 3.4 Liter engine and you're faced with a CEL code related to the Knock Sensors or the Knock Sensor Wiring Harness, this video will show you how to swap them out.

    Watched, good tips thanks. -


    Would have like to see Sean do some rips in that thing though!
    Also liked the catch can install. Maybe worth doing for a cleaner plenum

    @Timmah! You got any tips for getting to the front bank (circuit 1) knock sensor harness easily on a 2000 2.7L? I'm hoping I can at least get eyes on it without having to take out all of the intake...

    I haven't done a knock sensor replacement on the 3RZ but it looks like you got your answer above.
