Quizplus · Accepted Answer

During cranking mode, the PCM primarily relies on the Engine Coolant Temperature (ECT) sensor and the Throttle Position Sensor (TPS) to determine the appropriate air/fuel ratio. The ECT sensor provides information about the engine's temperature, which is crucial for adjusting the fuel mixture during startup.
