Ok car is throwing a code 22 - VTEC pressure valve

I've already tried/done the following:

checked oil level
I've done all my voltage checks, continuity checks, resistance checks for the switch, the solenoid and the wires in the harness involving the switch and solenoid etc.
I swapped out a good known pressure switch and a good known ECU.
I checked oil pressure and it was within vehicle specifications.
I jumped the Vtec solenoid and yes, it clicks.
I pulled apart the solenoid and the screen is fine, everything is clean. the plunger operates properly
checked for oil leaks. there is a small oil leak at the oil pan for the turbo return line, but it's minor and def not big enough to cause a pressure loss.

The only thing i have yet to try is swap a good known vtec solenoid assembly.

If it's not that I'm lost.
anyone have any other ideas?
