Failing oil level sensor

Whats up guys, I've been following the forum for a few months since I became a happy FZ6-N owner, and had the chance to learn a lot about my new bike.. now my time has come and its time for my first post, and tricky question ;)

Few months ago I laid down my FZ6 just to see if the slider would protect the frame and engine cover if needed.. What a terrific idea. Ok, it was doing its job. Bike up again, turned on the key, and before push start but after the startup diagnosis a flashing oil light/led came up.. 10x flash, pause, more 10x flash.. cycling.

Checking the service guide and the Haynes manual, It indicates low engine oil level. As the oil level is good, it must be a failed or fault sensor, or maybe a loose connector... I could locate the parts and connectors involved with the flashing oil light, its a sensor in the bottom of the engine, and its connecting wire runs all the way up to under the fuel tank, where it is reconnected and routed to the central wiring. Ok, checked the connections, shook the wire thats under the engine a little bit, and after a new key start, the light was gone.

As said that was a few months ago, and after that same thing happened a couple of times.. after checking if the oil level was good, and starting the bike for a few moments, or just maneuver it in the garage solves the problem.. as the wires are well connected, I believe I have a fault sensor. I do remember that the engine was hot the day I laid down the bike.. maybe the absence of oil on it damaged the sensor. As it is a little pricey, I found a replacement from a 2005 FZ6.. mine is 2009.

That explained, could anybody confirm if that 2005 sensor would fit and work properly in my 2009 FZ6? Here in my country there's was no FZ6 in 2005, so they couldn't confirm that in authorized dealer... I'm trying to cross reference the part number, actually I'm starting to look for that right now, I'll update the thread as the search goes.. but maybe some of you have access to this information and could confirm more quickly then I.

Any help is appreciated. Thanks !!

Hm.. Can somebody with some expertise in electrical components clarify the following quote (from the Haynes manual), regarding the warning that I'm seeing with the blinking

"Note: If there is a fault in the wiring circuit it will be detected by a self diagnosis function an the warning indicator will flash ten times, then go out for 2.5 seconds, and this will be repeated until the fault is repaired.".

Well, this is exactly the synthom in my case. My question is how this self diagnosis runs, because acording to this note the problem would not be the oil level gauge itself, but maybe the ohms returning from the self test is not in the expected range..

Thanks !

Unfortunately there are no fault codes.. just the flashing oil light (today has been one week since it last happened...). According to the Haynes I might have a short in this wiring..

I was just reading about a similar case with an R6 and his problem was a loose oil level switch.. not my case, I double checked and it is well fixed under the oil pan.

As soon as I have some free time and daylight enough I'll take off the fuel tank and test the connections again.

Thank you anyway !!

It sounds like the oil level switch is not showing the correct resistance to the meter, which is why you see the 10 flash signal. Attached are all of the relevant pages from the factory manual on checking the ohm value of the switch, etc. Hope this helps.
 
It's just hard to believe that manually laying it over would ruin a sensor, (or even loosen a connection)! I'm no electrician but it seems to me that maybe this programmed something into your computer causing the problem...something that is going to have be "wiped clean" from the memory. (What do I know?) Good luck!

Sure it will, Thanks !!
This weekend I'll run some tests and post the results.

I do remember of reading in some thread were was discussed about this kind of registry.. it seems like there's a "feature" that records like an history of excessive inclination, and that is saved in the ECU..... but in my case the engine was stopped, the key wasn't in the start position.. and oil light flashing ? Well who knows. I'll check about that.

The "lean angle sensor" is loacated behind the left rear pod (at least in my 07). I would think it would still work with the bike turned off but don't think its related/tied into the oil level switch. Tipping the bike over, not running shouldn't hurt the oil level level switch.

Did you try disconnecting the battery and re-set the computer? Also, did you check the torque on the 2 bolts that hold in the oil level switch? If their loose, you may not have a good ground causing your problems..

Uhmmm thats a good tip!! Two months ago, after I replaced the mid pipe (a MIVV no kat in place of the catalyst), I did disconnected the battery.. so it would reset the fuel map and create a new one; that time, after I re-plugged the battery, the flashing light came on.. and before that I had no sight of it.

Those two bolts are kinda hard to reach they are under the exhaust, I did checked the one more on the side but did nothing with the other one.. will do that for sure.
