Nope. The Engine Computer doesn't monitor oil pressure in any way. The sending unit is strictly to run the warning light and gauge on the dash.
The original question was, would the sending unit cause engine failure. The only way it could be considered a CAUSE of engine failure is if it was leaking, but the same can be said of a valve cover gasket or any other oil leak. The ultimate responsibility rests with the driver who is checking the gauges once in a while, but in a few rare cases the oil leak can be severe and sudden. Those are the ones that get our attention quickly and we stop the engine right away before damage occurs. Slower leaks, such as from a sending unit or seal will take longer to show up. Typically you will see the oil light flicker at idle or when going around a corner. Slower leaks don't usually result in engine problems if the oil level is checked periodically.
