Okay, forget the 325. Nissan had an issue with the code trees. The 325 would always set with any other code when there was nothing wrong with the knock sensor. Once the 335 is resolved, the 325 should not return.

description. You need to verify wiring to the harness. It could be a voltage supply to the sensor or it could be the gap. I would use an OEM sensor as a start.
Component Description
The crankshaft position sensor (OBD) is located on the trans-axle housing facing the gear teeth (cogs) of the flywheel or drive plate.
It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to change.
Due to the changing magnetic field, the voltage from the sensor changes.
The ECM receives the voltage signal and detects the fluctuation of the engine revolution.
This sensor is not used to control the engine system. It is used only for the on board diagnosis.
