Nissan Fairlady/300ZX Z32 Throttle Position Sensor TPS Twin Turbo (Early)

Terra Firma Automotive supplies genuine Nissan engine management components that restore precise throttle response and drivability to your Z32 Fairlady or 300ZX. This early twin-turbo throttle position sensor is the exact OEM unit engineered for the VG30DETT engines in 1990–1993 models. It accurately translates throttle plate movement into voltage signals that the ECU uses to optimize fuel delivery, ignition timing, and boost control, ensuring crisp off-idle response, smooth part-throttle behavior, and full-power performance under boost that these legendary twin-turbo cars are famous for.

Twin-turbo Z32 owners know how a worn or out-of-spec TPS can cause hesitation, erratic idle, poor boost response, stumbling during acceleration, or even limp mode. Replacing it with this authentic early-spec sensor immediately restores factory-calibrated voltage output and smooth signal transition, eliminating those issues and bringing back the sharp, predictable throttle feel Nissan originally engineered. Its precision construction and durable internals ensure reliable operation even in high-heat, high-boost environments where aftermarket sensors often fail prematurely.

At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM sensors and engine electronics that serious enthusiasts and builders rely on. Whether you are troubleshooting driveability problems on your early twin-turbo, refreshing the throttle body during a performance rebuild, completing a full engine bay restoration, or maintaining an original low-mileage example, this TPS upholds the exacting standards and legendary performance that define the 1989–1993 Fairlady Z and 1990–1993 300ZX Twin Turbo models.
