For those who have the high pitched noise coming from the engine compartment (not the ecu), the problem has been identified. The noise is
coming from the throttle bodies which are electrically controlled. I disconnected the harnesses and sure enough the noise stopped (also threw a code). Took this info to Nissan and he said that some of their other cars have this problem also.
