WARNING: This page is about a different car, the 2002 Infiniti QX4, 2001 Nissan Pathfinder, and 2001 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect turbine revolution sensor connector. Measure resistance between turbine revolution sensor harness connector terminals No. 1 and 2. See Fig 1. Resistance should be 2400-2800 ohms. Check for continuity between terminals No. 1 and 3, then 2 and 3. Continuity should not exist. If not as specified, replace sensor.
