1kz Ecu Pinout -

Factory intercooler sensors, electronic throttle bodies (drive-by-wire components mixed with cable control), and advanced electronic spill control. Critical 1KZ-TE ECU Pin Classifications

: Main battery power and switched power feeds.

If your vehicle does not have an OBD2 port (common on pre-2000 JDM models), you can read fault codes manually using the pins. 1kz ecu pinout

Most 1KZ-TE ECUs share a set of core terminals responsible for the engine's operation. When testing these, refer to the 1KZ-TE ECU Pinout Guide for exact voltage standards.

: Depending on the vehicle model (e.g., KZN130 vs. KZN165R), the connector pin count varies. Common configurations include the 26-16-22 pin layout found on later KZN165 models. Key Terminals : IGSW : Ignition switch supply. THW : Coolant temperature sensor input. +B / BATT : Main power supply from the battery. E1 / E01 : Main grounds. Most 1KZ-TE ECUs share a set of core

The 1KZ-TE is a 3.0L, 4-cylinder, SOHC turbo-diesel engine with electronically controlled injection. This system offers more precise fuel delivery and better cold-start performance than its mechanical predecessor, the 1KZ-T.

Throttle Position Sensor signal output back to the ECU. Output Actuators KZN165R), the connector pin count varies

The first few pins Tom identified were:

A broken or shorted SPV wire will cause an immediate "crank, no start" condition or trigger an uncontrollable engine runaway. Ensure the SPV ground via the ECU is pristine. Engine Speed Sensor (NE+ and NE-)

Crankshaft position sensor. The ECU won't fire the injectors without this signal. TDC: Top Dead Center sensor (Camshaft position).

: Often linked to the SPV (Spill Control Valve) or the ECD relay . If the ECU does not receive a signal from the NE (Engine Speed) or TDC (Crank Position) sensors, it will not pulse the SPV, preventing the engine from firing.
