Default CEL: P2646

hey guys..
so the CEL light that came up P2646..
it came up once before and I cleared it hoping that it was false alarm.
and it just came back up today, which is about two weeks after i cleared it the first time.

i checked my oil and its clear as new and at full. my only guess that i can think of is that the sensor mite have gone bad? possibly the wires..

anyone know what/where I can look to check?

Try the VTEC strainer screen. May be clogged, etc. I'd have a replacement screen and O-ring gasket on hand before taking it apart or Murphy's Law will invoke a torn screen or o-ring.
