This connector is essential for getting the engine to run inside a different chassis. | Pin No. | Circuit | Function | Notes | | :--- | :--- | :--- | :--- | | | W | Warning Light (Check Engine) | Grounds bulb to turn on | | 8 | AC1 | A/C Amplifier | Signal for A/C request | | 10 | SPD | Vehicle Speed Sensor | Input from cluster/VSS | | 12 | TACH | Tachometer Output | Signal to cluster | | 16 | FC | Fuel Pump Relay | Grounds relay to activate pump | | 17 | NSW | Neutral Start Switch | For starting (Auto Trans) |

Now, I will write the article. article provides an in-depth look at the pinout information for the 2UZ-FE ECU. The tables and voltage specifications in this guide are a helpful starting point for many common tasks, but for any major project like a swap or significant repair, it's critical to have the exact Factory Service Manual (FSM) and Electrical Wiring Diagram (EWD) for your specific model and year.

In this article, we will dissect the ECU pinout by generation (pre-VVT-i vs. VVT-i), explain every critical circuit, and provide professional wiring tips.

The is a legendary powerplant, known globally for its presence in the Land Cruiser 100 Series, Tundra, and Sequoia. While the engine is "million-mile" durable, performing an engine swap or troubleshooting a wiring fault requires a deep dive into the Engine Control Unit (ECU) pinout . 2uzfe ecu pinout

Always verify your ECU part number (e.g., 89661-6A420 vs 89661-6A610). The pinout often flips the location of the MAF and TPS signals between years.

Sequential control allows individual injector management.

There are of 2UZ-FE ECUs:

Check the IGF signal and the STA (Starter) signal. The ECU needs to know the engine is actively cranking to initiate the start-up fuel and spark maps.

Need to start the engine with a bare harness? Here are the mandatory pins:

Engine performance issues, such as stalling, high fuel consumption, or no-start scenarios, are often traced back to wiring problems. This connector is essential for getting the engine
