Both vdi and ssv have sensors to check there working and would generate a code if not...unless old pcm like mine was for ssv...but its not a hesitate its a hard cut if not working.  The apv ( motor) cycles on ignition start up check

Which would explain if it doesn't operate properly you don't get any codes

Yep, which is what i had when my SSV was not happening due to early pcm not having the fault code....does it Move freely should be able to operate it with a finger and then 12v bridge coil to operate?

I've charged up the vac tank and put 12v on solenoid and works perfectly. Got to do ssv next

Ssv takes a lot more vacuum to move. But it moves
