After a hard full throttle pull on the highway during a recent nice day my oil pressure light came on.

I immediately pulled over and shut the bike off. Shook and jiggled it, but upon restarts the light would not shut off as it normally did.

The oil cooler seemed a bit cool. I've found some threads that mention oil pump failures but no specifics.

2015 Scrambler Icon. Is this a known issue? What happened to my oil pressure? Sightglass shows there's fluid in it.

I know of at least one oil pump failure on a Scrambler.... (the guy that travelled around the world on a Sled).

You could at least check/replace the pressure sensor to rule that out.

Yeah, checking the sensor is easy. I'm going to go down to the bike and do some actual troubleshooting. I was hoping I'd be able to ground the sensor or connect it up to voltage but I don't know the engine or electrics of these bikes.

Do you by any chance know the part number? 53940302A?

Sorry, stupid question, but did you check your oil level ? :)

(Had an issue on a bike out of oil 2000km after service, apparently due to dealer negligence..)

If anything I'd worry it was overfilled. In my experience the fluid should come up to half of the sightglass, or marks along the side. Is that the same for this bike?

I'd have to check again to be quite sure but it seemed when I checked it on the side of the road the entire glass was filled.

I could not get a clear answer from the Ducati techs, do you know where the switch is located and when exactly it is triggered?

Received the oil pressure sensor last week, was able to install it today.

I only ran the bike as long as I was comfortable with, a few seconds, for which the light did not go off.

I did turn the engine over while the sensor was out, and oil is flowing, but if the light is on it must not be building pressure.

I need to tone out the wire from sensor to ECU to ensure the connection is good, and from there get a reading from the sensor and compare to what it should be.

Late update to sensor stuff. Grounding the sensor/doing the test described in the shop manual netted nothing new.

Been a fair bit of time, things get in the way.

Tore the bike apart, started with the oil pump.






There's some light scoring from the gears on the soft casing, and the hardened piston/valve thing has a very small amount of burnishing from what looks like wear.


I didn't take any pictures of the heads off but the cylinder walls still look freshly honed and have no scoring. I ordered a new oil pump but I'm not sure the damage within it is enough to have caused the loss of pressure. Does anyone think differently? While the engine is on the bench is there anything else I should check?

I know you’re past that stage now, but if you short or open the wires of the pressure sensor, did that make any difference. You sure the problem is in the engine and not electrical?
