An audible VGT test can be performed using a diagnostic system (AutoEnginuity, for example) to control the VGT system. With the diagnostic system active, run the engine and command the VGT to the closed position, or an 85% duty cycle. The turbocharger should make a hissing or whistling noise. Next, command the VGT to the open position, or a 15% duty cycle. Noise from the turbine side of the turbocharger should subside.
Duty cycle is percent of time that the signal stays at high level. It is typically expressed as the percentage of the period. As an example, a 100MHz signal (100 million cycles per second) has a period of 10ns. If the signal has 5ns high and 5ns low period, the duty cycle of this signal is 50%. However, if the high signal is 3ns and low signal is 7ns, the duty cycle would be 30%. 4.8k Views Â· View Upvoters
