2013 Knock Sensor

[BushPusher]

Engine light on code PO333 I am told that its bank 2 knock sensor high voltage. and of course the dealer price to fix starts at $500.00 and we go from there, And from what I have read it is more then likely the wiring harness to the sensors has been chewed so I will be replacing the harness and need help with torque specs for the intake manifold and the intake plenum.
If anyone has done this any tips would be very helpful.
Thank you for any help with this matter

I also am getting a PO333 code. we have an 05 V6 4L 4runner, so different engines. I think pack rats chewed a wire. the cel and vsc lights are on. I've read on this forum about what is involved in repairing the wiring to those sensors, and am dreading the thought of such a difficult fix. We are not equal to that extensive a job as getting to the knock sensors. I'd love to know if the vac light coming on would indicate maybe another place the buggers may have chewed?

Bergie: It's had to say what lights will come on when your engine light does
it depends on the accessories or options your vehicle may have,
If you look at the front of the engine you can see where a coolant pipe goes under the intake manifold you could try using a Endoscope with a lighted end you should be able to see both connectors to see if in fact that is the problem

and in most cases if in fact the wires are chewed your insurance company may pay for the repairs.
I have been using mouse away under the hood and spraying repellents into the space under the intake manifold and so far so good, hope this information was helpful.
replacing the knock sensor harness did take me 10 hours and i did not remove the passenger side cylinder head which is probably why it took so long,
