WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition switch OFF.
Disconnect EGR temperature sensor harness connector.

Check resistance between EGR temperature sensor terminals 1 and 2 as shown in the figure.
