Sensors like the Rail Pressure Sensor and Accelerator Pedal Position Sensor rely on a clean reference voltage generated internally by the ECU.
This guide is intended for professional automotive electricians and experienced tuners. The 2KD-FTV is a common rail diesel engine found in the Toyota Hilux (AN120), Fortuner, and Hiace (H200). Incorrect wiring can damage the ECU (Denso 275800-**** or 89661-*****). toyota 2kd-ftv ecu pinout diagram
