So i just bought this civic which had a broken timing belt. After changing everything that was broken/belt it runs good other than getting stuck in limp mode. It's throwing a P2159 Vtec malfunction and is stuck in limp mode rpm stopping at 4k.

So far ive changed the vtec solenoid, the oil pressure switch and changed oil and filter.
It still does this does anyone have any insight or know what might be the fix.
Thanks
