The following table outlines critical pins and their functions based on standard 2NZ-FE wiring diagrams: Voltage / Status A1 Always 0 Volts A A2 Idle Air Control (IAC) Valve 0 to 3 Volts (Ignition ON) A A3 Ignition Coil Feedback (IGF) 4.5 to 5.5 Volts (Ignition ON) A A6 Brake Lamp Switch Battery Volts (Pedal Depressed) B/C/D Injectors (1, 2, 3, 4) Pulse signals for fuel delivery B/C/D Sensors (NE+, OCV+, etc.) Crankshaft and VVT (Variable Valve Timing) signals Reference Resources The 2NZ-FE relies on a Powertrain Control Module
Toyota wiring diagrams use specific color codes (e.g., W-B for White-Black stripe). Good reference manuals include a color translation key at the front of the document; ensure your portable viewer displays colors accurately to avoid pinning mistakes. This ensures you keep the valuable user-submitted notes

The 2NZ-FE ECU pinout refers to the configuration and layout of the ECU's connectors and pins. It's a critical piece of information for mechanics, tuners, and enthusiasts who want to modify or repair their vehicle's ECU. The pinout diagram shows the location and function of each pin, allowing users to identify and connect wires, sensors, and other components.
