PO 340 code

Last week I got a check engine warning, on my 08
2wldr,3.0 six w/67,000 mi.
Oil and coolant were fine, changed air filter, still on.
Had the parts house use their code thing.
It came up PO340
cam shaft sensor
A circuit or
bank one something sensor.
Later that day and today there is no check engine light.
Whats going on here, did the computer get lonely?
Is there a connection to unplug and dialectic greased?
I asume the cam shaft sensor is magnetic.
If it doesn't have wing windows and a carb, I've got no clue.

Could be the cam sensor going bad, a bad electrical connection, or the synchronizer going bad. Do you have a rough idle? Does it sounds like you have a belt squealing if so the syncho is going out.
