Really enjoyed this video. I do something similar, I just apply -800mBar with the mityvac and road test to see if it 'boosts'

[@rmautodiag]

Yeh same sort of testing, just ruling out as many faults as possible using quick easy tests👍

[@doneill5150]

When viewing the PWM signal for the charge pressure transducer, you changed to frequency. I've tried frequency graphing for solenoid control and for newer Mass air flow sensors but other than seeing obvious glitches/drop-outs, I don’t get much joy from that type of graphing. How do find using frequency and what do you look out for?

[@rmautodiag]

Just makes it easier to see changes in the frequency or duty cycle. That's all I use it for.
