Yes, when a switch needs to be replaced it will either keep your light on even though there is proper oil pressure or it will leak oil through it's body while still turning the light off. If your light is on it is easier to replace the switch than the oil pump so always try the switch first. Early CB750 Honda's had an automatic chain oiler that was quite messy(early 70's) You may want to check your countershaft sprocket seal also. Degrease the area, clean, and take for a drive then check for the fresh leak.

2003 Honda CB 900 Hornet no oil pressure


Hi, Anonymous you may have a faulty sending unit to check for normal engine oil pressure, make sure the engine oil level is between the add and full marks on the dipstick. Remove the oil pressure sending unit, located on the right engine case, behind the oil filter mounting bracket, and replace/plum/or rig with a known good mechanical gauge that reads 0 to 40/50 lbs. Start the engine and run it until the engine oil reaches the normal operating temperature of 230 degrees. At 1,000 RPM, the oil pressure should be 2 to 4 lbs. at 2,000 RPM the oil pressure should be 30 to 38 lbs.

Whats the purpose of an oil pressure switch can it determine weather oil leaks from your grand prix or not?


The oil pressure switch or sending unit is a unit that receives an electrical signal showing what your cars oil pressure is.And yes it does partially does let you know when there is a problem somewhere in the oil system.For example if your filter gets clogged up your oil pressure will go down and then go up when you accelerate.If there was a leak in the system first you would probably see the leak And if the oil pump or oil pump shaft were to break you would have no oil pressure.So you can see the importance of having an oil pressure switch.I feel there are 2 guages that are important to watch are your oil guage and water temp guage they can tell you allot about how your car is operating.

Oil leaking from some sort of plug above the oil filter


If the leak is coming directly from above the oil filter it is more than likely the oil pressure switch is leaking. The seal around the Oil pressure switch could have gone bad and now it is leaking.

The oil pressure switch is located right above the the oil filter and above the cooling system cross pipe.
