Vgt Hysteresis Test. Hysteresis testing results. (Top) A linear fit was performed and the Can you test the VGT actuator without taking it off the turbo [c] If the Turbo Hysteresis test is a pass, repeat the test to see if the results are the same

It is basically a lag in the time from when the VGT is commanded to a position to when it actually reaches that position The step test is a sweep of the VGT mechanism from open-close-open that takes

If the results are the same, refer to section 57.5.1.1. The step test is a sweep of the VGT mechanism from open-close-open that takes VGT can be more significant in terms of ability of the turbo to continue to function § Damage can lead to noise, loss of performance or bearing (imbalance) failures § Never continue to operate a turbocharger that is showing evidence of foreign object damage § Fault Code 2387 and Low performance codes Cummins Internal Use Only
Experimental results of the hysteresis test. Download Scientific Diagram. VGT test? Discussion in 'Mack Forum' started by ChicagoJohn, Feb 16, 2017 The graph must be manually evaluated to determine a pass on the Step Test
Cyclic stressstrain hysteresis loop, Test E13 Download Scientific. A fail doesn't always mean a bad actuator, I have seen them packed with soot and work fine after it was cleaned out good. The only way to find out is to begin the troubleshooting procedure: The first step is to determine if there are any associated or related fault codes that could be causing the issue
