You can hope so. If you install a new sending unit, you will find out if it is something worse. Loss of oil pressure can indicate low oil level, damaged oil pump, a broken sending unit wire, a defective gage or a worn-out engine.
You need to remove the oil sending unit and install a oil pressure gage in it's place then start engine and read gage. Iwould tell you were the sending unit is but you did not say what you are working on.

You need to replace the oil sending unit.
Assuming you mean the engine coolant temperature sending unit, we need to know what engine it has, it makes a difference.
You need to be more detailed in your question. What year, size engine and kind of car.
To test an oil pressure sending unit, first disconnect the electrical connector and use a multimeter to check for continuity. Then, remove the sending unit from the engine and submerge it in a container with oil. Using a manual pressure gauge, apply pressure to the sending unit and observe if the gauge reflects the pressure accurately. If the sending unit fails to show the correct readings or continuity, it may need to be replaced.
You need to get a manual oil pressure gauge that reads LBS. per squire inch so you can read what the oil pressure is for sure. Then remove the oil sending unit from the engine and screew the oil pressure gauge in it's place and start the engine and read what it says. I would give you the oil pressure SPECS. and tell you where the sending unit is, but you did not say what year are engine size and what it is in.
You will have to remove the oil sending unit/switch and screew a oil pressure gauge into it's place and then start the engine and read the oil pressure.
The oil pressure sending unit on a 1989 GMC Sierra is located slightly above the oil filter. You will need a flashlight to find it. It may be hard to recognize it because it should have a heat shield around it as well. Look for its wire coming down from the engine compartment and follow it to the oil pressure sending unit. Drain your engine oil and remove the oil filter to make changing the oil pressure sending unit easier.
Your engine oil could be low check it when it cools and if level is fine your oil pressure sending unit could be bad or engine in need of rebuilding
There are several sending units, engine temp, oil pressure, fuel level to name a few. We need to know which one and also the year, make and model vehicle.
On a 2004 Chevrolet Trailblazer, the oil pressure sending unit is located on the engine block, near the oil filter. It is typically situated on the driver's side, towards the rear of the engine, near the intake manifold. You may need to remove some components for better access, depending on the specific engine configuration.
No. The harmonic balancer does exactly what it says. It is to keep the engine from viberating. You need to install a manual oil pressure gauge and run the engine cold and hot to determine if you really have a pressure problem. Most likely you have a bad oil pressure sending unit.
