What to know before swapping
VG30DETT has two throttle bodies and requires two TPS units; ensure junkyard pull includes both if available
Distinguish between Series 1 (1990-1993) and Series 2 (1994-1996) potential connector housing variations
JDM Fairlady Z may use different OEM prefix numbers (22620-Vxxxx) despite identical A22-631-W01 casting

The Nissan 300ZX Z32 platform utilizes the Hitachi-sourced TPS marked A22-631-W01 across 1990-1996 model years. Critical distinction: the VG30DETT engine employs dual throttle bodies requiring two identical sensors, while the VG30DE uses one. When junkyard hunting, verify the casting number A22-631-W01 on the sensor body rather than relying solely on Nissan's superseded 22620-40P05 service labels. Series 1 (1990-1993) and Series 2 (1994-1996) models may exhibit minor connector housing color differences despite identical internals. Test candidates with a multimeter for smooth 0.4V-4.6V sweep—dead spots around 2.5V indicate carbon track wear causing hesitation at 3000-4000 RPM. Installation requires setting baseline voltage to 0.35-0.65V at idle before tightening the M4 screws; on VG30DETT models, synchronize both banks to within 0.05V to prevent ECU conflict.
