The Engine Control Module (ECM) detects the following conditions: •Actual boost is less than desired boost by more than 30 kPa (4.4 psi) for more than eight seconds.•The current for the turbocharger solenoid is greater than 80% of the maximum value.•Desired boost is not ZERO.•The ECM has been powered for at least two seconds. The wastegate solenoid allows the engine to more precisely regulate the boost pressure to the engine. By closing or partially closing the wastegate solenoid, the ECM can increase the boost pressure. Typical wastegates will limit boost pressure to a preset limit. The wastegate solenoid blocks air...
