Signal from the crankshaft/pump position sensor for RPM detection. TDC+ / TDC- (Top Dead Center): Signal to identify the piston position for timing. THW (Water Temp): Signal from the engine coolant temperature sensor. THA (Intake Air Temp): Signal from the air temperature sensor. PIM (Pressure Intake Manifold): Turbo boost pressure signal. VA / VC / IDL (Throttle Position): 1kz ecu pinout

These configurations utilize a classic three-plug setup (often labeled as connectors A, B, and C) totaling up to 54 pins. | Terminal | Wire Color | Signal |

Engine cranks but will not start, or starts and instantly dies (frequently accompanied by Code 14). THA (Intake Air Temp): Signal from the air

Throttle Position Sensor signal output back to the ECU. Output Actuators

Controls the amount of fuel injected into the cylinders. This is a high-priority signal for engine starting and idling. TCV (Timing Control Valve):
