Low sump pressure mean,the oil pressure not meet the required pressure that is 20 psi during unloaded. The unit will shutdown when the machine controller display low sump pressure to avoid airend screw crash or metal contact with the housing. That is the protectin of ingersoll rand compressor.

Sump pressure is the back pressure created within the oil sump by pressure leaking past the piston rings. The pressure is usually very low due to the venting of the sump thru the oil sump vent (usually a tube or removable plug used for adding oil). If the vent was replaced with a plug, then pressure will be very high and cause oil leak. Higher sump pressure is also caused by adding too much oil into crank-case. If you are having other problems with compressor, post again. Good luck.

WHAT IS THE MEANING OF THE YELLOW SYMBOL OIL PRESSURE WITH AN EXCLAMATION MARK


If you have a yellow oil pressure warning light displaying then you may have 2 problems
1. Your oil level is way too low and needs topping up which very often means you are a sloppy owner that does not bother to regularly check the oil level in the engine and probably the other fluids as well.

2. There is a problem with the oil pressure and it is below the minimum needed to lubricate the engine.

What you need to do:

1. Check the oil level and top it up to the max level with the correct grade and type of oil as specified by Toyota for that engine.
Do not overfill the sump.
2. Check to see if the oil pressure warning is continuing to display when the sump has been filled to the correct level. If you still have the oil pressure warning you need to have it investigated and the cause of the low pressure rectified otherwise you will destroy your engine if you continue to run it with less than minimum pressure. A mechanic needs in the first place to connect an independent oil pressure gauge to the engine to check the actual pressure readings. This will also eliminate any possibility that there is an issue with the oil pressure sensor and sender unit (which is not likely). .

I am losing about 1/2 pint coolant every 1000 miles. the vehicle does not ovrheat at all.


check sump oil color
If grey that is coolant into the sump , probably from behind the water pump impeller
because water loss is not evident the fact that there is loss means that there is a leak some where
There is a drain hole under the water pump housing and if the seal is gone the water will leak out there under pressure and when operating and the coolant is lost in the air stream
Take it to an accredited radiator shop and have the system pressure tested

Remove sump


sump what sump.
are you asking an engine question?
what is wrong?, tell the story, or at least a tiny hint so we can get on the same page..
my wild guess is the engine oil pan (sump) and not tranny or other
sump like objects. or other many fluid containers all very sump like.
but the answer is in the FSM, buy one, and read how to remove anything on the car.
here state side we have alldata.com and dont need books until
we break 10 parts and then read the authortive manual.

Why is my 2007 envoy denali oil pressure dropping?


check oil level in sump. You may have to remove the sump to check for cracked oil pick up line . Check oil pump pressure regulator . replace oil filter as it may be blocked and dropping the oil straight back to the sump.

I have a 2003 Dodge Neon se there's a major oil leak between the engine and transmission how do I fix this


Check that the oil leak is not engine oil coming out before the bell housing ( sump gasket) If the oil is coming out of the bell housing inspection cover then it means box put and either flywheel off for a rear main seal or torque converter out for a seal in the box or converter.. If it is a sump or rear main seal check the engine oil level first and the PCV valve operation as excessive oil level and sump pressure will cause the engine side problems that you can fix without removing the box.

Water keeps overflowing over the ice making coils


Do you mean that it is overflowing the sump tray into the bin? If so there are two things to check. First make sure the unit is level. Second their is a simple water float valve much like an old toilet float that keeps the sump full. Turn the machine off and make sure that the float will stop the water flow 100% when the sump water level is just over the bottom of the water pump impeller. If the float will not stop the water flow either the water pressure is too high or the float valve is bad and has to be replaced. In general water pressure should be between 20-40 psi.

I have a flotec shallow well pump i can not get it to pump the water it stays at 20 pounds did i hook it up wromg


check your pressure tank. It sounds like it is water logged. This means there is no air pressure in it. If you're cut in pressure is set at 30 pounds you must have 30 psi of air pressure in the pressure tank.
