To diagnose the P1519 Acura code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
The target idle speed is in the Engine Control Module (ECM) memory for various engine conditions (coolant temperature, A/C operation, and other functions). The ECM keeps the actual idle speed at the target idle speed by switching the Idle Air Control Valve (IACV) ON/OFF to control the intake airflow. In addition, the IACV functions as the first idle valve to control the actual speed according to the engine coolant temperature. If the duty cycle signals are not inputted to a circuit that checks return signals in the ECM, a malfunction is detected, and the P1519 code is stored.
