Check for 12V at the SPV relay and ensure the NE+ sensor has continuity.
Located on the intake, used to fine-tune fuel density. 5. Essential Swap "Cheat Sheet" 1kz ecu pinout
These are calibration resistors inside the pump wiring. They tell the ECU the specific tolerances of that individual injection pump. Check for 12V at the SPV relay and
Understanding the 1KZ-TE ECU Pinout: A Comprehensive Guide for Swaps and Troubleshooting Essential Swap "Cheat Sheet" These are calibration resistors
Wiring a 1KZ-TE doesn't have to be a nightmare if you tackle it one plug at a time. Always verify your specific ECU part number, as there are slight variations between the Hilux (KZN165) and the Prado (KZJ95) pinouts, particularly regarding the air conditioning and automatic transmission shift points.
These are your main switched 12V power sources, usually coming from the EFI main relay.
This is the 5V reference power sent from the ECU to sensors like the TPS (Throttle Position Sensor) and Map Sensor. 3. The Injection Pump Interface (The "Heart")
