Before diving into the pinout, understand the hardware. The 2NZ-FE is a distributor-less, coil-on-plug (COP) engine using a wasted spark setup? No—actually, it uses a direct ignition system with a crankshaft position sensor and camshaft position sensor. The ECU (Engine Control Unit) is a Denso unit (often part numbers like 89661-0H010, 89661-52130, or 89661-0D240).

When patching an engine loom, avoid twisting wires and applying electrical tape. Use proper open-barrel crimp connectors and marine-grade heat-shrink tubing to seal wires against under-hood moisture and heat vibration.
Heated Oxygen Sensor (HO2S) feedback loops for closed-loop fuel control. The 2NZ-FE is a distributor-less, coil-on-plug (COP) engine
Most diagrams divide the ECU pins into four main groups (often labeled A, B, C, and D).
