When Toyota added VVT-i, the pinout changed significantly. Key differences: 2uzfe ecu pinout

Pinouts for the 2UZ-FE engine control module (ECM) generally include these critical signal groups: Power and Ground : Main ECM power sources (approx. 9–14V when ON). : Constant battery power for memory. : EFI main relay control. E1, E01, E02 : Main ground terminals. Ignition and Fuel #10 through #80 : Individual fuel injector control pins. IGT1 through IGT8 : Ignition timing signals for each coil. Critical Sensors : Crankshaft position sensor signals. : Camshaft position sensor signals. : 5V sensor power source. KNK1 / KNK2 : Knock sensor signals for Banks 1 and 2. Throttle Control (ETCS-i) : Throttle motor control pins. : Dedicated power source for the throttle motor.
