2uzfe Ecu Pinout
Whether you are diagnosing a P1120 (TPS malfunction), building a custom off-road buggy, or performing a stand-alone swap, you cannot guess the wiring. One wrong pin and you’re replacing a $2,000 ECU or frying a VVTi solenoid.
Use a multimeter to test for continuity from the sensors (like the oxygen sensors) to the ECU pins.
If you are swapping a 2005+ 2UZ, you have three options: 2uzfe ecu pinout

I'll open these pages to extract ECU pinout details, connector types, and other relevant information. search results show some information, but detailed pinout tables or diagrams are not directly accessible. The jdmfsm.info page might contain a table, but it's not fully captured. The drive2.ru page might have some information but is in Russian. The efiautos.com page seems to be a placeholder. The toyotanation.com page mentions ECU flashing differences. The v-tuning.eu page might provide some details. I need to search for more specific pinout information, possibly in PDF format. I'll also search for "2UZ-FE ECU pinout PDF" and "2UZ-FE ECU pinout diagram PDF". search results show some potential sources. I'll open: Whether you are diagnosing a P1120 (TPS malfunction),
There is no single universal pinout.
Before diving into pins, understand that the 2UZ-FE uses a Toyota EFI system (TCCS – Toyota Computer Control System). The ECU (Engine Control Unit) controls not only fuel and spark but also electronic throttle control (on later models), knock control, VVT-i (Variable Valve Timing with intelligence), and automatic transmission logic (when paired with the A750F or A343F). If you are swapping a 2005+ 2UZ, you

The Toyota 2UZ-FE is one of the most reliable V8 engines ever built. Featuring a cast-iron block and aluminum heads, this 4.7-liter powerplant is a favorite for custom builds, off-road trucks, and engine swaps.
Because the 2UZ-FE was produced from 1998 until the early 2010s, the wiring evolved significantly—moving from early non-VVTi throttle cables to complex VVTi systems with secondary air injection. Understanding the 2UZ-FE ECU Variations
