No Vtec After receiving and clearin code 21 Vtec Spool Valve

Alright Scholars, I need some help!

After my car was left sitting for about 6 months I got it back up and about. Driving around that night I noticed the thermostat was sticking closed and causing the coolant the push back into the overflow and steam. Well I figured I might as well order an Aluminum rad, fan and new thermostat while I'm at it.

Threw the rad, fan and T stat in one night along with a heater hose which decided to crack at the same time (Lucky timing). After throwing everything in I start it up and it throws a code . At first it threw a code for a temp sensor which I forgot to plug in completely. After I fixed it and cleared the code it threw code 21 Vtec Spool Valve. There is an option in Hondata to disable the spool error check. I checked this and the code went cleared.

Now the only problem is that I have no Vtec. Initially I though I knocked a wire loose or something so I checked all wires and they are fine. I also checked the vtec solenoid which is also fine. I tried various things tonight to no avail. I tried setting the vtec temp minimum to something very low and still no luck.

If anyone has any other helpful hints that would be GREAT!

Check continuity of the wire all the way back to the ecu.

Tried that everything appears to be ok. Had my buddy come over with a volt meter too. Took the Solenoid off and checked the screen. No problems there.
