Why is my oil pressure so low at idle?
Low oil pressure at idle only, will most often mean that the engine is low on oil. As more power is applied to the engine via acceleration, the pressure builds up inside the engine. High oil temperature can cause low oil pressure. A defective oil pump can also lead to low oil pressure at idle.
Can a faulty sending unit cause inaccurate oil pressure readings?
When it detects oil pressure in the vehicle, a switch trips and either the light shuts off, or the gauge becomes active. A faulty oil pressure sending unit can result in inaccurate oil pressure readings and warnings. So, it is important to recognize the signs of a sending unit that needs to be replaced.
What should the oil pressure be at idle?
low oil pressure at idle. believe it could have been whilst driving through a muddy/watery area. way but drop’s 1/3 mark (maybe is half?). When fully warm its just above the ‘L’ Mark. there and they look ok. and the pressure reads 37 psi. it would appear the engine is in spec according to the manufacture manual. relief valve. My question is?
What should the oil sending unit voltage be?
Check the voltage to the gauge it should be a steady 12-13.5 volts. — A oil pressure gauge in actually a voltage gauge with a different face. 12 volts on the supply side and the sending unit actually varies the resistance to ground. 55 people found this helpful.

Manual says the pressure should be 40 psi at idol, but the gauge is inaccurate. You can test it by T-tapping a pressure gauge in line with your oil pressure sending unit, and see if you are actually running the correct pressures. Question 1, how often do you change your oil?

What does it mean when your oil pressure is low?
However, if the oil pressure gauge continues to show a low pressure reading even after the car engine is warm, and there are no other problems that you can tell, the culprit may be a defective oil pressure sending unit. The same would be applicable if the gauge reports very high oil pressure levels as soon as the car’s engine is started. 3.
