No, the oil level can affect the the oil pressure if it is too high or low. The coolant level has no connection with the engine oil pressure.
maybe not. check engine oil for color and quantity. if oil is white to grey, then there is coolant leaking into engine.no pressure might be caused by bad radiator cap.this will also allow coolant to escape
A pressure switch reads pressure not level.
Check you oil level! Also there should be a wire attached to around the area of the oil pan. That sensor controls the coolant level, oil level and that wire.
Oil pressure as measured by the guage on the dash is usually a measure of the pressure put out by the oil pump and not an indication of a leak or low engine oil level. If you have a leak your best indication of that will be puddles on the ground, on the underside of the engine or a milkiness looking color in the oil (as seen on the dipstick) or in the engine coolant.
If you are losing coolant, you probably have a bad cylinder head gasket. Too much coolant system pressure will drop your engine oil pressure.
Need more info as to which sending unit, oil pressure, coolant temperature or fuel level.
It's oil level or pressure. If level ok, pressure test.
Oil level and oil pressure are different. You don't need to have full oil to get normal pressure.
Most likely it is the headgasket being blown. Check the coolant level. If there is oil in the coolant and water in the oil there is your clue.
Oil level sensor is on side of oil pan.
Low oil level, low oil pressure, failed oil press sending unit.Low oil level, low oil pressure, failed oil press sending unit.
Bad head gasket? Oil mixing with coolant?
