Engine Temperature

[RoyF]

Morning All,

Does anyone know where the dash temperature display on a a 2013 R1200GSA (pre LC) is taken from? Is it from the Oil Temp sensor or the Cylinder Head Sensor?

The reason I ask is that at some point in the distant past the 'Check Oil' function has stopped working, just giving the "----" symbols and not the "----OK" etc, in the same way as if all the pre-conditions are not met on a cold engine.

I've eliminated both the oil level sensor and wiring back to pins 45 and 40 of the ECU, the side stand switch is fine, plus the usual hot engine, in neutral, side stand up and waited the 10 plus seconds. So guessing it 'might' be thinking the oil is not up to temp although the temp gauge on the display is working fine.

Any ideas appreciated,

Cheers, Roy.

That OK does not show all the time. I asked the service manager about it and it's not supposed to.
I have ridden with the oil screen showing and it has taken a good while for OK to show and then it goes off.
If there's a problem, you'll get the red warning light.

Dash - ambient temp is taken from a sensor in the beak area if i recall

Oil is level only

So why do I have an engine temperature guage that goes up as the engine oil warms up.

 

[Mistacat]

The GS911 shows Left Cyl head temp, Right Cyl head Temp and engine Temp.
I assume the engine temp is from the oil temperature sensor.
Air temp one under the beak and the other one is in the airbox.

 

[Mistacat]

I might be wrong but I think this is the sensor right hand side of the engine.

 

[botus]

you can toggle an engine temp option in one of the modules - but I never saw any other features turn up in the cluster

diagnostics picks up individual left & right cyl temps

Air temperature : 17.5 °C
Engine temperature : 90.0 °C
Temperature (cylinder head 1) : 108.0 °C
Temperature (cylinder head 2) : 108.0 °C

I'm still puzzled how my Jun 2007 GS gets this engine off or at idle - asked GS911 support and they haven't shed any great ideas yet - 2011 GSA lists it at 0%

Engine load : 45.58 %

Because you have a later bike prehaps? that has these sensors displaying live data (the OP's bike is an 06)

 

[er-minio]

On the older hex:

Bars on the side is oil temp, as per icons.

“temperature” function is clearly ambient temperature and there is a pointy probe under the beak.

 

[botus]

the bar chart temp display is std across the board - twin cam confused the idea swapping to the other side for no sensible reason

I thought OP was on about a digital temp display of engine temp

check oil level is some madness of confusion that must meet multiple parameters before it magically behaves

a) engine running
b) engine at normal temp
c) bike upright
d) bike stationary
e) bike in neutral

So is mine. I didn't mean it actually showed the temperature in °C or °F. just the temperature guage on the right of the cluster that goes up as the engine temperature does.

Blimey it's 20 this year

Thats for that siddo, that's exactly how mine always used to work, when it eventually decided everything was hot enough I used to got the 'OK' if I toggled to 'OIL' when sat at the lights etc, then that disappears as soon as the wheels start moving, but haven't seen the 'OK' come up for some time just the dashes, not that I often used it. The flashing RED warning is for no or very low oil pressure which says something has gone very wrong and engine damage is likely imminent !!!

Yep, that's right Santa, ambient temp comes up when you toggle through the display with the info button, before you get to 'Oil Level'. I was wondering where it gets its temp info from on the bar graph on the left hand side.

Hi Gazza, Santa was on about the display along the bottom, Ambient Temp and Oil Level should be displayed in there, the bar chart up the left side is for Engine Temperature as you correctly mentioned.

 

[RoyF]

Thanks Mistacat / Botus for the pic and the GS911 info, think my next plan will be to plug the GS911 in and see if I get logical readings similar to Botus above at all the different temp locations, plus I'll try unplugging the Oil Temp Sensor as well to see if that stops the bar graph working..... I'll report back ... Cheers Guys

e) bike in neutral
f) side stand must be up

temps are in the engine DME real time values (go to the bottom and toggle all options) then "play"

please post all all values including engine load value - (running and off, ideally - only if an early non twin cam bike)

OP what is it your trying to find out what is or isnt working ?

Ambient temp (Air)
Oil temp (Oil)

your explanation in post 1 is odd , and may have confused everybody

On a pre 2013/4 bike

Oil temp is the vertical display either side of the Kombi (depending on year)

The - - - symbol you refer to is only for oil level and model year specific - it has a specific set of operating parameter s - if they aren't met you wont get an oil level reading

 

[RoyF]

OK, cheers for that Santa......

Just to clarify, I'm trying to work out why my 'Oil Level' check is not working as it should in the bottom of the display when you scroll through 'Range', 'Clock', 'Average Speed' etc..... I used to always get 'OK Oil' once the parameters as per Botus's message above were all met, but I can only seem to get '------ Oil'.

So my fault finding took me to:-
Checking the oil level float switch, Open when float is up and oil level is ok, Closed when float is down and oil level is low (bench tested that and also another known good one).
Checked wiring from float switch (out of engine) to pins 45 and 40 on ECU which check out fine, continuity when float is down, open circuit when float is up

Next step (and point 'b' is where the confusion may have started) was to double check to see if any of the 'conditions' were not being recognised for some reason.

a) engine running - an easy one, yes
b) engine at normal temp - So my thinking was maybe the ECU wasnt seeing the engine temp, the bars on the left of the display work as they should, but where was it getting this reading from?, have confirmed that it is from the oil temp sensor as per Mistacat's pic, unplug it and the bars disappear. GS911 is showing oil temp being measured and increasing as it warms up, to around the 90 to 110 degrees mark, and left hand and right hand cylinder head temps rise equally and not far off of the oil temp so that all seems fine.
c) bike upright - another easy one, yes
d) bike stationary - yes, if bike not stationary, oil check disappears from menu as soon as you start moving
e) bike in neutral - yes, and green N illuminated (although I think it still works if the clutch is pulled in if its stationary and in gear ?)
f) side stand must be up - yes, and side stand switch working as it should.

So that's as far as I've got....... There are no other errors with the bike, I've had it from new and everything else is 100%, it would just be nice to see if I can get this working again

Cheers, Roy

the oil level is often hard to get to behave - with so many parameters that must be met its not that hard to see why

'------ Oil' is not he same as '---' which I think means conditions not met, yours I'm guessing is saying its not getting the level - have been posts years back about the level sensor can misbehave - not sure what to suggest

on the GS911 you can often toggle stuff to show up for testing.... a recent addition to the GS911 tool has been more coding choices to molest - is the level stuff on in the engine and cluster coding choices set up correctly?

 

[Santa-2512]

Lets start from the top

What model,
What year
What month of manufacture (normally in your handbook or on your V5)

This is the extract from a R1200GSA (model code 480 eur)

just thought, have you got the bike on the centre stand when your doing your checks , or are you sitting on it ?

I always do mine sitting on the bike with the engine running, normally after a run

and do you get the warning displayed if you cant get a reading ?





Found it - oil level sensor looks like RH cylinder
Might want to start with the connector - for damage water ingress etc
