WARNING: This page is about a different car, the 2003 Acura 3.2CL and 2002 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.

Dip the sensor in ice water, and measure the resistance between its terminals.

Then pour hot water on the sensor, and check for a change in resistance.
Compare the resistance readings with the specifications shown in the graph; the resistance should be within the specifications.
