In most compatible vehicles (like the Toyota Echo/Yaris 1999–2004), the PCM (Power Control Module) is located behind the glove compartment .
| Pin Range | Function | |-----------|----------| | 1–10 | Power, grounds, main relay control | | 11–20 | Sensors (MAP, TPS, ECT, IAT, O2, VVT) | | 21–30 | Injectors, ignition coils (IGT/IGF) | | 31–40 | Idle air control (IACV), fuel pump relay | | 41–50 | MIL, diagnostic (TC, SIL), alternator | | 51–60 | AC, speed sensor, starter signal | | 61–64 | +B backup, +B main |
, , and Vios . These guides are essential for diagnostics, engine swaps, or wiring repairs, as they detail the specific voltage values and signal types for each pin. Key Technical Specifications 2nz Fe Ecu Pinout Pdf 186
While this guide covers essential functional pins, exact terminal positions shift across vehicle models (e.g., a 2002 Toyota Echo vs. a 2010 Toyota Vios). Complete schematic variants, wiring colors, and plug layouts are typically documented in official Toyota Electrical Wiring Diagrams (EWD).

Determine if you are testing a power feed, ground, sensor input, or output control line.
: Swap coil locations on the engine blocks. If the code stays on the same cylinder, back-probe the associated IGT signal wire at the ECU harness. Check for a broken circuit between the computer housing and the engine compartment plug. toyota 2nz fe engine manual The Toyota 2NZ-FE
: This is a crucial computer system that controls the engine. The ECU manages the engine's performance, ensuring optimal fuel efficiency, emissions, and power output.
When analyzing the pinout diagram, several critical pins must be identified first for the engine to start and run properly: 1. Power Supply and Ground Circuit
: For 2nd generation Yaris models, the 1NZ and 2NZ engines often share the same pinouts, but 1st generation pinouts may differ significantly between the two.
The powertrain control module (PCM)—traditionally located behind the glove compartment in vehicles like the and Toyota Yaris —manages critical functions through a complex array of multi-pin connectors.
