: In many models like the HiAce or Surf, the ECU is located behind the glovebox or near the passenger-side door pillar. : Pinouts can vary slightly between the , KZN185 , and
: 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. 1kz ecu pinout
Toyota 1KZ-TE engine control unit (ECU) manages essential diesel engine functions such as fuel injection timing and volume via a multi-pin configuration. For the widely used : In many models like the HiAce or
: Timer Control Valve; manages the injection timing advance. Variation by Model and Year Common configurations include the 26-16-22 pin layout found
Below are the critical pins found on the most common 26-pin + 16-pin + 22-pin configurations (found in later model Prados/Surfs).
This is the heart of the fuel system. If the ECU doesn't send a signal to this pin, the engine will not start. It is often paired with a Spill Valve Relay (SVR) TDC and NE Signals:
