Toyota 2kd-ftv Ecu Pinout Diagram -
The 2KD-FTV uses a Denso ECU (typically part numbers like 89661-0Kxxx or 89663-0Kxxx). The ECU has four main connectors labeled A, B, C, and D. Each connector is a 16-22 pin rectangular plug.
| Connector | Color | Typical Pin Count | Main Functions | |-----------|-------|------------------|----------------| | A | Gray | 22 | Power, grounds, injectors, fuel pump | | B | Black | 22 | Sensors (crank, cam, MAP, IAT, ECT) | | C | White | 16 | Actuators (SCV, EGR, turbo, glow plugs) | | D | Green | 16 | CAN bus, diagnostics, immobilizer, A/C |
Note: Pin numbering is usually embossed on the connector housing. Always verify with your specific ECU part number, as minor variations exist across vehicle models and years.

The intermittent short circuit was causing erratic signals to be sent to the ECU, confusing it and leading to the power loss and limp mode issues. Ahmed cleaned and replaced the connector, ensuring it was well-sealed against future moisture intrusion. He then cleared the error codes from the ECU and took the vehicle for a test drive. The Hilux performed flawlessly, its power smooth and consistent.
The Toyota 2KD-FTV is a 2.5-liter, common-rail diesel engine found in popular vehicles like the Hilux (AN120/130), Fortuner, Innova, and Hiace. Known for its durability, the engine’s electronic control unit (ECU) is the brain behind fuel injection, turbocharging, and emissions control. Having an accurate ECU pinout diagram is essential for diagnostics, wiring repairs, ECU swaps, or piggyback tuning.
This article provides a detailed breakdown of the 2KD-FTV ECU connectors, pin functions, and practical tips for using the diagram. The 2KD-FTV uses a Denso ECU (typically part
Common intercept points:
⚠️ Warning: Modifying signals can cause engine damage. Always use a tuner experienced with common-rail diesels.
Below is the typical pin assignment for the 94-pin variant (Connectors A, B, C). We have organized this by function rather than raw pin number for easier reading. | Connector | Pin | Wire Color |
