G650X Country Stalls Over-N-Over When Cold - Page 3

I switched out the coolant and coolant sensor last weekend. The immediate cold-start stalls are history!

I also decided to pull the trigger on a GS-911, and here's what it read today:

Code:

#2012-11-24 16:07:25 
#GS-911 Android V1.1 
#G650 Xcountry 
4433: Engine Coolant Temperature Sensor Malfunction, Short-circuit to Positive or Open-circuit. The fault is not present now. 
17460: Tank ventilation valve, Open-circuit or output-stage overloaded. The fault is currently present.

I suspect 4433 would've been triggered by starting the bike with sensor disconnected, and not just if the sensor is bad. I regret not having a dealer pull the codes before I began tinkering. The other fault (17460) showing is due to the canister laying on the garage floor, I just need to short the disconnected plug I think.

Reading the real-time values using the GS-911, I'm seeing huge fluctuations from the lambda sensor, and maybe this sensor is malfunctioning. The bike doesn't run perfectly smooth, it kind of struggles, then catches up, then struggles. I need to do some more research and ride some more and see what I can come up with.

another success story. First took off the carbon canister, since it was the easiest. Did maybe make some differnce, hard to say. I then changed the temperature sensor and the problems are 99% gone. Measuring the resistance it was hard to say there was anything wrong with the old one, but no more cold engine stalling.
