P1349 CODE

1998 Lexus GS 300 • 6 cylinder 2WD Automatic • 193,000 miles

I own a 1998 Lexus GS300, and recently the Check Engine Light, VSC, and VSC OFF lights came on. An OBD II diagnostic scan showed a P1349 code. I checked the oil control valve screen and it was completely clean and unclogged. I also put 12 volts of power directly to the camshaft timing oil control valve and it appears to be functioning properly. Any ideas as to what could be causing this problem?
