Overheating

[Hooli]

Considering the oil temps quoted earlier (on at 120c, off at 108c I think) you'd be surprised how quick it pulls the oil temp down. I've heard them come on a few times when doing stuff on bikes in the garage like balancing throttles back when it took me ages as I wasn't very good at it.

With a fan it's not always the size in diameter there is also speed and pitch of blades.

So finally found the dealer mode connector. Someone has had the undertray off and it was tucked underneath it.
Been for a run to get code. Took ages because weathers cooler.
It came back c11 cam position sensor.
Now to find out if faulty sensor is causing overheating or overheating is affecting sensor.

I'd go with the latter, they are simple hall effect sensors & can fail.

When the ECU decides that is faulty it'll use the crank sensor to decide when to spark, fire injectors etc, which isn't as accurate but good enough for the engine to run.

Worth checking the connectors for it too, along with the big grey/white one under the LH side cover as everything from the engine runs through that to the ECU. Oh & pop the ECU out, the drain hole can block so it's sitting in water, which never helps.

Am I right in thinking latter is the second of the two "overheating is affecting sensor"

Obviously my fervent prayers  of never hearing "overheating" again in this thread have not been answered.

[Irish in Oz]

Then "overheating" should be referred too as "running hot".

[GSXKING]

Very hot if it is actually over heating 

[KiwiCol]

"running hotter than I'd like"?  or "a bit warm" . . .

[Eric GSX1400K3]

Or Andre might like the term "under cooling"?

Well, it's operating above it's current safe working temperature limit. That should keep Andre happy...

If the sensor works how I think it does, then it's a small electromagnet. As the cam turns an oblong block on the cam enters the sensor's magnetic field, this causes the sensor's magnetic field to change shape, that in turn creates a small current in the other coil inside the sensor & that produces a voltage in the sensor lead. Being such small things it wouldn't take much to get a short or something when hot as the insulation can't be thick.

Just an update. Changed the Cam Sensor which wasn't cheap at just over £100.
That sorted it all out so faulty sensor was affecting fueling and causing overheating.
