Passenger Seat Occupancy Sensor - 1991 300ZX Z32

The Nissan Z32 300ZX relies on a passenger seat occupancy sensor (OEM: 98830-40F01) to signal the SRS module when the right-side seat is occupied, preventing unnecessary airbag deployment during collisions. This pressure-sensitive mat component, often bearing Denso supplier castings like 197400-2010, fits all 1990-1996 model years regardless of VG30DE or VG30DETT engine configuration. When pulling from junkyards, inspect the sensor mat for foam cushion disintegration and check the pigtail connector—part 31036-30P01—for green corrosion caused by decades of rain intrusion through compromised T-top seals. Installation demands carefully peeling back the seat upholstery without tearing the metal retention rings; the sensor adheres to the cushion pan with factory adhesive that must be thoroughly cleaned before securing the replacement. Persistent airbag flash codes 33 or 34 typically indicate this sensor or its harness has failed.
