    Question on engine temperature sensor

    I have had a lingering issue with my R1150RS which is more annoying than anything. When the ambient temperature hits about 90 degrees - my temperature reading in the RID disappears and re-appears in a few minutes. Last year I spoke to my dealer about the problem and asked if he thought it was likely to be the sensor or the RID. He said it could be either and neither would be easy or inexpensive to fix and he would start by replacing the RID. So I bit the bullet and replaced the RID. Sure enough it didn't fix the problem. After reading a review of the GS-911 diagnostic tool in the MOA I decided to bite once again and spring for the tool. Sure enough reading the engine controller I get:

    277: Engine Coolant Temperature Circuit Malfunction, Short-circuit to Positive or Open-circuit.
    This fault occured 22 times.
    The fault is not present now.

    So I'm now supposing it's the temperature sensor (doh!) but I haven't found it in the on-line parts fiche. Anyone run across this or know where it is? Or if you've seen this problem seen some other cause?

    "temperature sensor" for the R1150RS. not sure if that's 100 percent right, but i think it might be.

    Cool! I see it now under "various switches" in the fiche. A little pricey but way less than the RID. I should have started there.....

    I would check the connections where the temp sensor plugs into the harness. I presume the dealer already verified the integrity of the connection where the RID connects to the harness, but that could be the culprit too.

    Good point. I'll do some electrical troubleshooting before swapping any more parts.

    Is reading the fault codes not a test the dealer should have performed before an unnecessary RID replacement? Just curious .....

    One would think. I have since switched dealers after about a dozen "issues" - this being one of the more minor.

    well, i suppose if it's any consolation you could sell the old RID on ebay.

    Well, with two oilheads in the family and an intention to hang on to them - I think it will eventually.

    I hope that cures you of ever expecting the dealer to fix anything in a reasonable manner. One is probably better off left to ones own devices and time and the help of the internet.

    Cool! I am on the fence and may spring for one as I do all my own maintenance too. My dealer is 100 miles away and we have a good relationship as he knows that I will come to him for parts and those things I will not do (i.e brake bleeding)

    All depends on your dealer. I have a very good relationship with mine and that is VERY important. I also must say that when travelling, most dealers I have had to go to for tires or minor issues, will help you out very quickly even if they are slammed. A lot depends on your own attitude and cheery smile.. YMMV
