BIG (or little prob?)IMRC valve position sensor circuit low voltage

[hankus]

My 2003 CRV (88K miles) runs fine but last night I noted engine check light...and this am checked it out.Code P0661 (per Auto Zone) which is
"IMRC valve position sensor circuit low voltage due to 1) open or short circuit;2)poor electric connection;3) failed IMRC position sensor"

I had AZ turn the light off and so far so good....What if anything should I do?Can I do it anything myself?
