Oil Temperature very low

Post by Akalnoky » Thu May 12, 2016 8:01 am

Looking for some answers as to why my bike's oil temperature reading is very low.

This morning the air temp was 9C, after 20 minutes of operation the gauge was reading between 29 - 32C.

Even on the hottest of days with air temp at close to 40C the gauge reads no higher than 48C.

This has always been the case since new, bike now has 20,000k. Coolant temp is usually around 4 bars and never goes above 5 bars.

Would it be a faulty sensor? Where is the sender for the oil temp located?

Any advice or just ignore it as I've done for 27 months.

Temp sensor is broken. You might be down on power as well since the ecu might think the engine is colder than it is.

It isn't uncommon and there are a few posts with the same problem.

Thanks mate - no difference in power noticeable, I run the full Rottweiler Stage 4 system with an Arrow decat link pipe so power has never been an issue!

I had the same fault, changed the oil temp sensor as a warranty item, now it's good. But... We did have it dynotuned a few times before changing to a working sensor and it showed a little too rich mixture. The mixture was leaned... The cause (partially) for the richness might be the faulty sensor but there were other changes too, like PCV, aftermarket air filter, decat... I think two or three ponies could be found if dynoeing it again with a working sensor - because for example a change to a Unifilter air filter cost about 2hp... Sure I would not notice it there is a nice overflow already...

And if it doesn't cause gas in oil - who cares if it goes a bit too fatty... Maybe the Green Party? :mrgreen:
Do like the others do, you end up being like the others, so... Well, seems to be a lot of KTM riders around.

How hard is it to change the sensor? I have a 2016 which is doing the same thing.

Is the sensor part of the oil filler cap?

It's very easy. 2 x 8mm bolts and a connector.

Awesome.

I think I'll just hold off until the sensor goes completely out. I'm not losing power and the sensor is 150 lol.
