1kz Ecu Pinout < 2026 Update >

Toyota updated the 1KZ-TE engine management system across different vehicle models like the Hilux, Surf, Land Cruiser Prado, and HiAce.

Spill Control Valve (Injection Pump Actuator). These are critical wires that control fuel volume. PCV: Pump Control Valve (if applicable).

Relays the exact position of the throttle pedal pedal to manage fueling transitions. 4. Glow Plug and Auxiliary Controls 1kz ecu pinout

: If the engine cranks but does not start and the Check Engine light does not illuminate when the key is turned to "ON", the ECU is likely not receiving power. Check the +B (EFI relay power) and BATT (constant power) pins for 12V using a multimeter. Toyota updated the 1KZ-TE engine management system across

| Pin | Signal | Notes | |-----|--------|-------| | A1 | NE+ (Crank position sensor) | 2-wire VR sensor | | A2 | G2+ (Cam position sensor) | | | A3 | NE- / G2- | Common ground for both sensors | | A4 | THW (Coolant temp sensor) | 5V thermistor | | A5 | THA (Intake air temp) | In airflow meter | | A6 | VG (Airflow meter signal) | Analog 0-5V | | A7 | E2 (Sensor ground) | ECM ground ref | | A8 | VC (5V sensor supply) | To MAP/MAF/TPS | | A9 | VTA (Throttle position sensor) | 0-5V from idle to WOT | | A10 | IDL (Idle contact switch) | Throttle closed | | A11 | STA (Starter signal) | From ignition switch | | A12 | NSW (Neutral start switch – A/T) | Park/Neutral | | A13 | SP1 (Speed sensor 1) | From combination meter | | A14 | SP2 (Speed sensor 2) | Transfer case (4WD models) | | A15 | KNK (Knock sensor) | | | A16 | EGR gas temp sensor (if equipped) | | | A17-A24 | +B, +B1 (ECU main relay power) | 12V with ignition |

Often caused by a disconnected PIM (Map Sensor) wire or a faulty TPS signal. PCV: Pump Control Valve (if applicable)

Ground for injectors/actuators (high current). E1 (Ground): Logic ground for sensors. 2. Sensor Inputs

Below are the most critical pins required to get a 1KZ-TE running, particularly in a conversion scenario. 1. Power and Ground Constant from the battery. +B1 (IG): Switched ignition (power when key is on).
