2007 MKZ AWD, suddenly (as in just started today out of the blue) has started showing the oil lamp and low oil pressure message when sitting at idle (around 500-600rpm) and only seems to happen after the engine has warmed up. No odd sounds, no knocking or tapping when the light is on, oil level is right on top of the grid on the dipstick. It's been 10 degrees the past couple of days out, could that do anything? Could the oil pressure sender/sensor act this way? I'm starting to get freaked out already by all of the comments on other forums about other cars saying things like, "Well the engine is probably just worn out and it'll be dead soon ". I've had other strange electrical behavior since it's gotten cold as well on startup like a brief "Check brake system" message that flashes and goes away, usually followed a few seconds later by the airbag light staying on. Shut the car off and turn it back on and all is fine, airbag light goes out. Sometimes when this happens the climate control unit turns off. Could a battery going out cause all of this? Or *gulp* an alternator?

Edit: Also the title I wrote was "Low oil pressure, plenty of oil". Not sure why it came up with Plnb haha.
