What does code P1565 mean?

P1565 · VolkswagenIdle Speed Control Throttle Position Lower Limit Not Obtained

P1565 on a Volkswagen means the engine control module (ECM) commanded the throttle valve to a specific low idle position, but the throttle position sensor reported that the blade never reached that lower limit. The ECM monitors the correlation between the commanded idle speed control duty cycle and the actual throttle plate angle, and it sets this code when the measured position stays above the expected minimum for a calibrated time.
