Well the first issue has just started. Wife told me over the weekend that the oil light would come on periodically when slowing for a light or turn. Not always and not frequently. No noises, vibrations or problems. Checked oil level & it is fine. Just changed oil about a 1000miles ago. No changes in program, Mobil 5W40 TDT and Bosch filter. Need to take it in to see if oil sensor is shot or oil pump is going.

No need to take it in as the problem is almost certainly the oil pressure sensor down by the oil filter (it's obvious); oil pumps almost never fail and would be a bear to get at as in pulling the engine difficult. Just replace the sensor (oil pressure 56028807AB - alternative Standard Motor Products PS317 - stay away from the Crown one) which is under $50 at Amazon. To swap - undo electrical plug (likely have to lift a tab to unlock); using appropriate size wrench unscrew sending unit; screw new sender in and lightly tighten it with wrench (I don't know but suspect it has a tapered NTP thread; if so you may have to "crank" it down a bit but not too hard to seal); hook electrical plug back up. You should not lose a significant amount of oil while doing this if you are brisk with the swap.

Just to add to what Pap suggested!
Put some teflon tape on the pipe threads, that insures no leakage.... :wink:
And he is correct, mine started blinking a couple years back and I replaced the sending unit and it never was a problem again... :roll:

Before going expensive, change the oil filter. I once had same issues after a oil change. Changed the oil filter and never came back. That was 100+k ago. I assume the filter was bad, the crd oil filter needs to hold pressure.if that doesn't work, look at what others mentioned.
