2uzfe Ecu Pinout Jun 2026

Camshaft position sensor signals used to sync fuel injection timing. THW: Engine Coolant Temperature (ECT) sensor input. THA: Intake Air Temperature (IAT) sensor input. VG: Mass Air Flow (MAF) sensor voltage signal.

For ECU models such as 89666-60170, the wiring involves multiple connectors.

Note: Always verify with your specific ECU case number as pinning changed between 4-speed and 5-speed automatic transmission models. 2uzfe ecu pinout

Critical sensor for cold-start enrichment and radiator fan control.

If you are putting a 2UZ-FE into a different chassis (like a 4Runner or an older Hilux), keep these "gotchas" in mind: Camshaft position sensor signals used to sync fuel

Without stable voltage supply and reference grounds, the microcomputer cannot process engine computations.

The serves as the master electrical map for managing Toyota’s legendary 4.7-liter V8 engine. Found globally in durable platforms like the Land Cruiser 100-series, Sequoia, Tundra, and Lexus LX470 , mastering this specific pinout configuration is essential for performing diagnostic troubleshooting, harness repinning, and standalone engine swaps. 1.
