Idle and load on a JDM VG30DE Fairlady hang off the throttle-valve switch. When that sensor drifts, the ECU sees the wrong plate angle and the car hunts or stalls. The Genuine Nissan Throttle Valve Switch is the factory TPS for naturally aspirated Z32 cars.
This switch bolts to the throttle body and reports valve angle to the ECU. One is required. User application is JDM Fairlady Z32 VG30DE non-turbo, 1990–1994 only. It is not the twin-turbo VG30DETT sensor.
A worn TPS throws codes and ruins idle. Replace it when the signal is noisy or the connector is broken, then set base idle per the factory procedure. At Terra Firma Automotive, we supply this genuine Nissan Fairlady Z32 NA throttle valve switch so JDM VG30DE owners can restore throttle-position input with the OEM sensor. Choose Terra Firma Automotive for authentic Nissan engine-management parts built for the Z32.
