A Z32 that pulls timing or throws a knock-sensor code often has a broken lead in the valley, not a dead sensor. The Genuine Nissan Detonation Knock Sensor Harness (part number 24078-30P00) is the short EGI sub-harness that carries the knock-sensor signal from the engine valley to the main engine control wiring.
Fits Fairlady Z and 300ZX Z32 cars with VG30DE or VG30DETT, USDM 1990–1996 and JDM 1989–1996, naturally aspirated or twin-turbo. The harness sits in the heat and oil of the V6 valley, so the insulation cracks and the connector fails long before the sensor itself.
Replace this sub-harness when the knock circuit is open, intermittent, or being serviced with the sensor. At Terra Firma Automotive, we supply this genuine Nissan Z32 knock sensor harness so Fairlady and 300ZX owners can restore the detonation signal path with the factory piece. Choose Terra Firma Automotive for authentic Nissan engine-control wiring built for the Z32.
