: Spill Control Valve, which regulates fuel injection volume. TCV : Timing Control Valve for injection timing. S-REL / M-REL : Relays for the spill valve and main power. Grounds : E01 / E02 : Engine grounds. E1 / E2 : Sensor grounds. Standard Voltage Reference (While Idling)

When testing these pins, standard voltage values are used to verify sensor health. For example, the terminal (Turbo Sensor) should typically show 1.3–1.9V at atmospheric pressure, while VC (Sensor Power) should consistently output roughly 4.5–5.5V when the ignition is ON. 1kz ecu pinout

Check for 12V at the +B pin and toggling voltage at the SPV pin while cranking. : Spill Control Valve, which regulates fuel injection volume
