I'm having an issue with check engine light code P1259 on a 97 civic Y8 motor (the d15 Japanese equivalent.) I have just replaced the VTEC Solenoid, oil switch and the passages for the oil is clear but still have the engine light on. Car obviously won't engage VTEC and immediately shifts right before it would kick in. There was a ton of oil on the VTEC Oil pressure switch before I replaced it. I really don't want to take it to the shop if i don't have to. Anyone have any ideas? Any help would be great.

P1259
-Open or short circuit condition
-VTEC Solenoid Fault (Replaced)
-VTEC Pressure Switch Fault (Replaced)
-Blocked Oil Passage (No blockage in oil screen.)

Also was given code P0705
-Short in Range Switch circuit probable cause
-short circuit condition
-Faulty transmission range switch
