Crankshaft Position Sensor. The ECU uses this to determine RPM and timing.
The Toyota 2KD-FTV engine is a legendary workhorse. Known for its presence in the Hilux, Hiace, and Fortuner, this 2.5L D-4D common-rail diesel engine is prized for its durability. However, when it comes to engine swaps, performance tuning, or troubleshooting electrical gremlins, having the is essential.

Turn the ignition ON. Probe the VCC pin on the ECU or at the Rail Pressure Sensor. If it reads 0V or significantly below 5V, a shorted sensor is pulling the ECU voltage down, or the ECU internal regulator is damaged.
If the engine fires for exactly one second and then dies, check the wire linking the EDU's confirmation pin (IJF) to the ECU. The ECU shuts down fueling if it does not receive confirmation that the injectors responded. Tips for Finding the Exact Diagram for Your Vehicle

You can copy and paste this directly onto a site like IH8MUD, New Hilux, Tacoma World, or a diesel tuning forum.
This guide is based on publicly available information and community resources. Always consult a qualified automotive electrician for complex wiring modifications.
Toyota updated the 2KD-FTV ECU multiple times. Early models (non-intercooled, mechanical turbos) use entirely different pin placements than later models (intercooled, variable nozzle turbos). Always cross-reference the OEM part number on your ECU casing with your diagram. The ECU uses this to determine RPM and timing
Unlike petrol engines where the ECU drives injectors directly, the 2KD-FTV common-rail system uses high voltage (up to 150V) to trigger the piezoelectric or solenoid injectors rapidly.
This is a common question on forums (e.g., PakWheels). The exact pin depends on the vehicle model and transmission type. A full pinout diagram should clearly mark the “SPD” or “Vehicle Speed Signal” output. Without a complete diagram, probing the connector with an oscilloscope while driving is risky – refer to the factory wiring manual instead.
