The " door ajar" message stays on even when alll doors closed, believe it probably a sensor in one door, how to check sensor on doors also, " low oil pressure" message also stays on though manual check of oil level indicates full?

Low oil pressure does not mean the oil level is low, it means the oil pressure is low. It could be a weak / failing oil pump or the gauge may be reading inaccurate. As for the door ajar light, it is a common issue with new model Ford / Mercury trucks and SUVs. One of the door ajar switches have failed or become sticky. Try lubricating all door latches including rear with WD40.

Once you've determined which door the car thinks is ajar, a liberal dose of canned air (like you clean your computer with) sprayed in the door latch should work wonders. It works on my Ford Explorer.
