R1150GSA GS-911 Fault code 277

[Stujw70]

Hi All.
I have had a ongoing issue with the cold starting of my 05 1150GSA which i had been slowly trying to resolve.

I purchased a second hand GS-911 which arrived today and first go this fault code shows up.

Could this code be sufficient to confuse the bike whilst attempting to start? Its fires up straight away once its got going, but once its cold again it can take forever to start if at all.

Would this be pointing to the airbox air temp sensor or does the bike have another i should be looking to replace?

thanks very much

Take a look at the temperature sensor reading in live data. I think it is the air temperature sensor.

ok, thanks will do next time I'm off, ta

I'm kind of assuming the short circuit to earth might be a knackered switch open or closed

That code indicates a fault in the OIL TEMPERATURE circuit. That sensor is mounted on the front right side of the engine and plugs in under the fuel tank above the alternator. That sensor is key to a cold start.

That's brilliant thanks very much, shall get a replacement switch organised

Before buying a replacement oil temperature sensor, use your GS-911 to see what the oil temperature is reading and compare it to the bars on the rid. The other possibility is that you have a short in the wiring harness.

Thanks for that, interestingly the RID When I bought the bike showed 2 bars all the time even on start up and all the way through to long run outs and now shows all the bars no matter what Can't get near the bike for a week + unfortunately, but some good leads for when I can. Will drain the tank and get a good look at all the connectors & wiring.



Thanks for the help

Do you not think it might possibly be a short circuit to earth....?

Not being a expert on electrics, I assumed the short circuit to earth might indicate a
Knackered switch.
But presume not, by the reply. So what's a 'short circuit to earth' for a layman please?

Ta muchly

Means the wire has been damaged somewhere and is touching something at earth (-ve) potential either the frame or a wire that is connected to earth.

Ok thanks very much, shall make a good visual inspection then.

Had the opportunity to get the tank off and have a good look around. Overall the loom across the whole bike is in pretty good shape with no obvious problem. However the item that flags up with the fault code again looks in ok shape, but I'm assuming the image below of corrosion around the plug base is what's causing the fault code to flag up?

From looking on real oem the switch has a washer between it and the engine block which is what I think looks like mush between the sensor and block.

Both those, the temp sender and the oil pipe have base gaskets that leak. And your's look like they are very likely candidates in the near future.

 

[Stujw70]

Thanks Neil, thought it might be the case. On the to do list once this initial snag us chased down, will get the gasket ordered.

Stu, Unplug the oil temp sensor and measure the resistance when the engine is cold. Here's a table of what its resistance should be.

A bad oil temp sensor or wiring will cause starting problems.

 

[Stujw70]

Thanks for the assistance with this snag gents. Area cleaned up and refinished.

New temp probe fitted and no fault codes picked up and touch wood seems to have resolved the starting issue.

Only snag to sort is the RID oil temp shows all the bars straight off. Fuse 3 pulled, loom connections next check.

Thanks again

The oil temp probe goes to the RID and to the Motronic. It sounds as if the wire to the RID/Motronic is shorted to ground since a HOT sensor is LOW resistance.

Thanks Roger, will get digging.

Nothing showed up as a fault on the GS-911, upon further scanning.

Stu, When you turn the key on, use the GS-911 to display realtime values. If the bike has been sitting several hours your air temp, oil temp and ambient air should read about the same. Have you made use of the realtime value feature?

Not yet, will fire up the laptop next time as have been using it via the IPad only for the AutoScan.
