Triumph Speed 400,125 Miles, Low Oil Pressure

Just from anecdotal evidence from speaking to a former owner, I think it's fairly common that there is a fault with the oil pressure sensor - a quick Google seems to yield similar stories. I'd not ride it until your dealer looks at it, especially if it's going in soon anyway.

ps welcome to the forum.

 

Did you leave it on the kickstand while idling? Not uncommon to cause oil starvation when a vehicle is idling and not upright. My old Astra estate would chunter along parked halfway on the pavement, then all at once start clattering!

 

Really! Assuming sensor/electrical integrity, if the OP light comes on when idling on the side stand, either the oil level is way too low or the main bearings are knackered. Running with low oil is inexcusable and anyone who does deserves a wrecked engine as a lesson.

In the case of the 400 in this thread my money's on a dodgy sensor or wiring/connector.
Never heard of an ECU "learning new oil pressures" either.

 

Sorry to ask this - it was the oil light and not the engine management light?

The 400's have a problem with the engine light coming on for no reason which I don't think has been solved yet. Software updates have not always fixed this, although it did on mine..... while I still had it anyway.

I had a minor bump and sold it!

 

I think what happens, certainly with my old car, was the oil pickup being to one side, so when the engine fires oil around, it doesn't return quickly enough to keep scavenging. My T140 was the opposite, left pot used to start smoking...
