Correct. Watch all of it!
Low side commanded vs actual
High side commanded vs actual
Injector PW
In that order. Any of those 3 can trip you up. But if one goes, it usually will affect the rest. For example, if low side doesn’t keep up, it will cause high side to drop and injector PW to widen. But the reality was, it was just the low side not keeping up. Hope that makes sense.
