Oil Pressure Light After 15 min

[Magicman]

Hello,
I have done a search to no avail. I am hoping one of you wise folks can help. I have a 2003 Monster 400s. My oil level is good. The bike starts up fine, the oil light goes out within seconds after start-up.

But about 15-20 minutes into every ride the oil light illuminates and stays illuminated for the duration of the ride. Is it probable that this is a heat issue? Is the oil pressure switch heat sensitive? Outside air temperatures during rides vary between 30-33 degrees C. I don't live anywhere close to a Ducati dealership so I am hoping to troubleshoot this myself. Thanks for any input.

MM???

Faulty oil pressure sensor?

Faulty oil pressure sensor?

My thoughts exactly, try to swap that first.

Thanks, will try that.

You can get a spare non-Ducati sensor for very little money. If you have an Opel/Vauxhall/GM in general dealer in your area then ask for a part with S/N 12 52 573 or alternatively 12 38 696.


Left is original, right is the replica. A little shorter, yes, but it works and is incredibly cheap

They can get moisture in the connection. Unplug it for a while, and try letting it dry out.
