Check the wires to it, if theyre good then replace the knock sensor.

Yes a knock sensor can cause a loss in power, but generally will at times kill the engine. Replacing them is pretty simple, but if that is the code your getting then as soarer stated, check the condition of the wires first. If they are good, then replace the sensor.

You can probably get the plug with pigtail from toyota but you cannot just buy a wire and simply install. Like i mentioned above check to see if the wire looks brittle if not then replace the sensor.

I had this issue. It happened to me because I was taking off the intake manifold, got frustrated and yanked on it without realizing there were still things plugged in. Needless to say several plugs ripped, I fixed them with *additional thicker gauge* (wrong) wire, and the circuit fault codes were trigged. Went back and removed the extra wiring and soldered stock to stock and its gone. Sometimes a cheap sensor may cause that too i've heard

Any forums on how or what to take off to get to the sensor??

I hate to be the bearer of bad news but you're gonna have to completely remove the intake manifold to be able to do your best job at fixing the wiring and even removing the sensor.
