Low Oil Pressure Warning question.

[Stucat]

So in the 390 miles I've put on the new TTSE, I have received two "Low Oil Pressure" warnings on the display.  Both occurred in the exact same circumstance; which I believe to be related to how the electrical system and computer function rather than a mechanical issue with the engine.

I am in the habit of using the Engine Cut-Off switch to shut down the engine prior to dis-mount.  So twice now when I have put the bike on it's side stand and hit the Engine Cut-Off, I have received the "Low Oil Pressure" warning as the engine has stopped. 

I'm not concerned about this as the site glass is full on daily inspections and I receive no other warnings when accelerating hard, cornering at steep lean or braking hard.

I read in the manual that Triumph considers use of the ECO switch to be for emergencies only.  I assume that by using the ECO, instead of the Ignition Switch to shut down, I'm somehow freaking out the ECU.

My question is; am I causing harm?  Should I change my operating procedures?

Thanks!

Two separate issues here, Oil Pressure and Oil Level are different subjects.
If Oil Level is low - top it up and check for leaks.
If Oil Pressure light is lit - it need to be checked by the dealer just to make sure oil ways etc. are clear.

I'm unsure about using Kill Switches, my understanding is they short out the coils to do their job as an Emergency measure. I wouldn't use Kill Switches to switch off the engine under normal conditions.

Thanks for your thoughts Steve.  Over on our side of the pond, most motorcycle instruction advises riders to shut down using the ECO; thus allowing both hands to remain on grips and access to primary controls (front brake).  Which is helpful with parking on hills around here.

In pre-ECU/CAN motorcycle electrical systems, the ECO simply removed power from the ignition system.  It's apparent that with the ECU in the TTSE, it's much more complicated than that.

I don't think this is an oil issue, rather an electrical/sensor issue; but will have the dealer read out the codes and check pressure at my next visit.

Regardless, looks like I should change my shut down procedure.

Regards!

I have had low oil pressure warnings upon Spring Startup the past 2 seasons, after the bike sat dormant all winter.  Posted about that earlier.  Bike is a '13 with 74,500 miles on it, first showed up about 52K.

Low OP warning occurred upon startup, or sometimes after riding a short distance.  No sign of distress from the engine whatsoever.  Shut down, restarted, light goes off.  Took about 3 restarts the 1st year, 2nd I was in Texas and was just getting ready to take the TTSE to the San Antonio dealer when the bike quit throwing the LP light after 3 days of intermittent warnings.  Ran 10,000 miles since then this year, no re-occurrence.

As far as testing the switch and oil pressure, that ain't gonna happen.  No codes are stored and there is no provision to check the sender with DealerTool or the genyewwhine BMW analyser either I'd guess.

The sender itself is BURIED, requires removing all the tupperware, gas tank, air box, throttle bodies, alernator... A HUGE undertaking on this beast.  I doubt the dealer would do it for free..  AND, ... after attaching the test guage, the bike would have to be totally reassembled to run the engine!!!!

I was going to replace the sender at the 20K inspection I just did, but was thwarted by the buried wiring, connectors, the difficulty and amount of disassembly required for this one simple ( on other machines ) task.  I have extended warranty so decided to let 'them' do it if it recurs persistently.

You can just see it above the clutch housing through the 3/4" or so hole in a web between the cylinders and the clutch housing.

Might be another test point for oil pressure, if one is found I'd LOVE to know where it is...

In the case of the Low Oil Pressure Warning light illuminating after using the "Emergency" Kill Switch
to stop the engine, the answer probably lies in the comments found within the Owners Handbook :

The engine stop switch is for emergency use.
If an emergency arises which requires the engine to be stopped,
move the engine stop switch to the STOP position.
Note:
• Although the engine stop switch stops the engine,
it does not turn off all the electrical circuits and may
cause difficulty in restarting the engine due to a discharged battery.
Ordinarily, only the ignition switch should be used to stop the engine.

The text I've underlined above is probably the reason -
The engine has stopped, so the Oil Pressure HAS dropped,
but the electrical circuit for monitoring oil pressure is still "on",
so ( correctly ) indicates the situation.

From the first day, I stop the engine with the side goat leg, no problem until today

So what happened "today" miss?

Thank you Coconut, your speculation equals my own.
