Patient is a 2004 K1200GT and has been running fine. While working on another bike I discovered an incompatibility between my new GS-911 WiFi unit and my iPad Air2 when connecting over wifi--the GS-911 cannot see version MA2.4 Motronics when configured that way. Opened a ticket with Hexcode, they are aware of the problem and looking to fix in the next software or firmware release. So, per their instructions I connected via laptop and USB cable on my own bike, just to verify that PC/USB would work.
An autoscan reported the error shown in the title. I have not noticed fuel mileage issues nor any running issues, but clearly the code indicates a problem somewhere. I cleared all the codes, connected the GS-911, started the bike cold, and allowed it to idle until up to temp. So, I've collected a CSV file of relevant data and am trying to narrow down the possible problems. My three main suspects are fuel pressure, fuel volume (obstructed fuel filter?) or a bad O2 sensor. The bike is due for a new fuel filter so I will make that change, along with installing the BeemerBoneyard replacement for the curved hose. I do not have a fuel pressure gauge but could probably borrow one if need be. That leads to the questions on the O2 sensor:
1. What is considered a normal lambda value at cold startup? And at normal operating temp?
2. As the bike was coming into temp I noticed some wild fluctuation in the lambda readings. Is this normal, or should the value move progressively and be relatively stable? BTW, this was a straight idle, no throttle blipping until near the end just before shutdown.
3. If I need to replace the O2 sensor does anyone have the correct Bosch cross-reference number? I'm betting it's a part I can get at a FLAPS at a significant savings if I can get the Bosch number.
I have cleared all codes on the bike and will be taking it out tomorrow morning for a 100mi run so I can read codes again to see if the code is recurring.
Thanks for the help,
DeVern
