The 2KD-FTV ECU (Engine Control Unit) manages engine performance by processing signals from various sensors and sending commands to actuators. Key pin categories include:
Power & Grounding: Essential pins such as +B (switched power), BATT (constant battery power), and E1/E2 (engine grounds). Sensor Inputs: THIA / THA: Intake Air Temperature. THF: Fuel Temperature. THW: Water (Coolant) Temperature. PIM: Turbo Pressure (Manifold Absolute Pressure). VG: Air Flow Meter signal. VAF: Throttle position or air intake related signals. Actuator Controls:
#1, #2, #3, #4: Individual fuel injector signals, often routed through an EDU (Electronic Driving Unit/Injector Driver). GREL / GLOW: Glow plug relay control. EGR / VRV: Exhaust Gas Recirculation valve control. SCV: Suction Control Valve for fuel pressure regulation. Reference Diagrams & Technical Guides
