2uzfe Ecu Pinout -

These engines feature a mechanical throttle body with a traditional Throttle Position Sensor (TPS) and an Idle Air Control (IAC) valve. They utilize non-VVTi cylinder heads and a simpler 4-plug or 5-plug ECU configuration.

If you are reading this, you likely have a 1,000-pound gorilla of an engine sitting on a stand: the legendary Toyota 2UZ-FE. Known for its bulletproof iron block, cross-bolted mains, and ability to run half a million miles, this 4.7L V8 is the heart of the Land Cruiser 100 (LX470), Tundra, Sequoia, and 4th-gen 4Runner V8.

Connect the BATT pin to a fused, permanent 12V battery source.

The following are critical terminals for troubleshooting or standalone wiring: LC100 Factory Service Manual Description Constant Power Always maintains 9–14V for ECU memory. Switched Power Main power from the EFI relay when ignition is ON. EFI Relay Control ECU signal to trigger the main power relay. E1 / E2 / E01 Critical sensor and chassis ground points. Crank Position Engine speed and timing reference signal. Ignition Triggers Signals sent to individual ignition coils. Injector Control Individual ground-side triggers for fuel injectors. Throttle Position Power (5V) and signal for the throttle sensor. MAF Sensor Mass Air Flow signal (typically 0.5–3.0V at idle). Key Variations by Vehicle Land Cruiser 100 (1998–2002): These engines feature a mechanical throttle body with

You have a no-start condition. Your scan tool won't link. Here is the diagnostic workflow using the pinout:

Standard 2UZ-FE ECM terminal specifications (specifically for common models like the 2006 Tundra) typically include the following key pins: Power & Ignition MREL (E3-8) Known for its bulletproof iron block, cross-bolted mains,

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.
