Oil pressure drop persists after oil sending unit replacment.
I drive a 2013 F150 ecoboost 3.5L 4x4. 110K miles.
Had issue with oil pressure drop at idle and back to normal once gas pedal
was pushed. No issues with power, driving or noise. Truck runs perfectly.
Checked engine. No oil leaks observed. Change oil regularly and timely and
oil level has never dropped.
Replaced the oil sending unit,(which is a pain the a@# to get to, and not
fun,,lol). and no alarm or drop in pressure for about a week. However the
low pressure drop alarm now pops up for a few seconds and returns to
normal while driving. Still no issues with driving, power loss or anything out
of the ordinary.
