Odd oil pressure warning light behavior on Spring Startup
« on: June 03, 2016, 01:02:13 am »
2013 TTSE, 52030 on the odo.  Started her up today 1st time this year ( I was on an extended snowbird adventure just got back in town ).   

Bike has been in winter storage since late November last year.

Fired right up as always, sounded normal.  All systems working properly.  Temps in the high 60's F.

Left the garage, about a mile out the red oil pressure warning on the tach illuminated.  I immediately killed the engine with the kill switch.  No warning on the LCD.  Coasted to the side.  Verified the oil level was correct.  Restarted, no warning light. Engine sounded perfectly normal.

About another 2 miles, same thing.  Same action, same result. 

Made a stop, bike sat about 30 minutes.  Restarted all normal.  About 3 miles, same thing, same result.

rode another 30 miles, no more warnings occurred.

Engine never sounded oil-starved.  No LCD warning.   Performance nominal.

this has never happened before.

Going to hook up the DealerTool in a bit and see if there are any codes.

Anyone else ever have this happen???

DealerTool reports no codes, all seems totally normal.  Another 20 mile run produced no abnormal oil pressure light activity...

Maybe the part that produces the constant 'low voltage' warnings has been a bad influence on the part that signals 'low oil pressure'...

Keeping a Watchful Eye.... Nervously....

Hi janfmiller,

I've never heard of that but I thought I'd just chip in to say that you don't need DealerTool
to check for any DTC's ( Diagnostic Trouble Codes ).

Most of the Fault codes will also put the "MIL" ( Malfunction Indicator Light ) on.
The MIL is extinguished after a certain number of "No Fault" starts ( typically 3 ),
and the code(s) are deleted from the ECM Memory after further "No Fault" starts ( typically 40 ).

You can have any stored Codes displayed on your Instrument Panel - See here for how to do this :
Servicing Data, Reference Info. & DTC ( Fault ) Codes

At the end of the most recent Post there is a downloadable Word document
that explains the meaning of the various codes you might encounter.

When there is an intermittent fault it is often useful to pull over,
check for any codes at the roadside, take a snapshot of the Instrument panel screen
with your your trusty Smartphone, and then you have it for reference if,
later on - when you arrive at the Dealer, the code has since been erased  :028:

Cheers  :821:

Thanks Coconut, I neglected to remember that, I've got your doc printed out and stored on the bike.  Guess I was too focused on not melting down the mill...  Great advice as always!!

After having left your bike for an extended time stored (I assume it was based on your post), did you change the oil before taking it out? Even if the bike hasn't run in all that time, water can condense inside the engine/oil pan/transmission. Best to start it up, make sure it works, get the oil hot, shut it down, and change it immediately after an extended storage.

I know lots of people DON'T do this and everything is fine, but I would caution against it -- the laws of physics aren't on their side.

Not a bad idea.  That said, the last thing I do in the fall is change the oil so it's not stored with contaminants in the oil.  I don't start the bike during the winter, but I do turn it over by hand occasionally and keep the battery on a tender.   Been doing so for 50 years, never have seen any problems.  Before...

Managed to get another 30 mile ride today, been severe thunderstorms and rain for day, oil pressure light never came on in every type of riding I could subject her to.  Hopeful but worried... 

I was thinking of checking the oil pressure switch wiring, but, like so many things on this beast, that would require major disassembly including removing the throttle bodies and alternator!!!
