Similar to EGR, if Pin A47 sees an open circuit, the EVAP system fails and can cause rough idle due to purge valve logic errors.

If you are reading this, you are likely staring at a Toyota Vitz, Platz, Echo, or Yaris (XP10/XP90) equipped with the 1.3L 2NZ-FE engine. You have a wiring diagram in one hand and a multimeter in the other, but the factory service manual is too vague. You searched for "2nz Fe Ecu Pinout Pdf 186" because you need the definitive truth about the 186-pin engine control unit. Also check Toyota repair manual RM-0000 series (RM-0006
Why "186"? The 2NZ-FE (and its larger brother, the 1NZ-FE) typically uses a 4-row, 186-pin ECU connector layout (often a 4x46 or 4x47 configuration depending on the vehicle chassis). The number "186" refers to the total terminal cavities available. However, not all pins are used. Depending on whether your car is a manual or automatic (CVT/4AT), with or without Smart Key, or has ABS, approximately 110 to 130 pins are active.
Warning: Mistaking a ground for a 5V reference on this ECU will destroy the processor. Accuracy is life. This article serves as your schematic companion for the mythical "Pinout PDF 186."
