Diagnostic Procedure
WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect PNP switch harness connector. Check continuity between ground and terminal No. 2 (Black wire) at PNP switch harness connector. See Figure - Figure . Continuity should exist. Also check circuit for short to voltage. If problem exist, repair as necessary and retest system. If problem does not exist, go to next step.
- Disconnect PCM harness connector. See Figure . Check continuity of Green/Orange wire between terminal No. 1 at PNP switch harness connector and terminal No. 42 at PCM harness connector. See Figure and Fig 1 . Continuity should exist. Also check circuit for short to ground and short to voltage. If problem exists, repair as necessary and retest system. If problem does not exist, go to next step.
- Check continuity between appropriate PNP switch terminals (component side) with shift lever in appropriate position. See PARK/NEUTRAL POSITION SWITCH CONTINUITY
table. See Fig 1
