Diagnostic Procedure (A/T)
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. See Fig 1. Check continuity between ground and PNP switch harness connector terminal No. 2 (Black wire). See Fig 2. Continuity should exist. Also, check circuit for short to voltage. Repair circuit as necessary and retest system. If circuit is okay, go to next step.
- Disconnect ECM harness connector. See Figure. Check continuity of Green/Orange wire between PNP switch harness connector terminal No. 1 and ECM harness connector terminal No. 43. See Figure and Fig 2 . Continuity should exist. Also, check circuit for short to ground and short to voltage. Repair circuit as necessary and retest system. If circuit is okay, 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 . See Fig 2. If problem exists, replace PNP switch. If problem does not exist, go to next step.
- No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLESHOOTING - NO CODES article.
