Vehicle speed signal for cruise control and transmission logic. STA (Starter Signal): Informs the ECU that the engine is currently cranking. A/C (Air Conditioning): Input/output for A/C compressor load compensation.

Leave out: EGR, immobilizer, AC idle-up, fuel heater, and vehicle speed sensor (unless you want cruise control). 1kz ecu pinout

: Spill Control Valve (critical for fuel injection timing and starting). Performance & Troubleshooting Vehicle speed signal for cruise control and transmission

Generates an AC signal tracking crankshaft/pump rotation speed. If this signal is missing, the engine will instantly stall. 3. Key Engine Sensors Leave out: EGR, immobilizer, AC idle-up, fuel heater,

Note: Always verify orientation by looking at the wire side of the plug rather than the ECU header pins, and cross-reference your specific ECU part number (e.g., 89661-xxxxx) before pinning.
