I'm not sure if this is cool or not but I'm asking for help in diagnosing a sudden engine problem in my 2013 SERK. My closest dealer is 50 miles away and over a nasty mountain summit so I'm trying to ferret this out without making that trip!
The bike was not ridden for about the past month...I know, shame on me! I kept it on the battery tender, with a fresh, full tank of fuel. Yesterday was nice weather (by November Wyoming standards) so I attempted a ride. Bike started fine, sounded great. Rode 1 mile and suddenly/spontaneously it started sputtering and backfiring and killing (limp-home mode, lost a cyclinder).
Pulled the following codes in this order from DTC:
P0134-Front O2 Sensor Open/Not Responding
P0154-Rear O2 Sensor Open/Not Responding
P1353-Front Cylinder No Combustion EFI
P1511-EFI Power Management Mode
P2101-EFI Motor Circuit Range Performance (Actuation Error)
P0031-Front Heated Oxygen Sensor Low/Open
C1095-Front Brake Switch Open (ABS)
C1216-Rear Brake Switch Open (ABS)
Next, I cleared DTC's to determine and eliminate historical codes versus current issues. Attempted to re-start and run bike but it coughed and sputtered so much it wouldn't run on its own unless starter was cranking. I then re-retrieved DTC's and only code P0031 (Front Heated Oxygen Sensor Low/Open) was retained in diagnostic program.
Questions:
1. Is it correct to assume all codes that were successfully cleared by the above process were "historical" (from prior issues that have since been resolved...and there have been several!) and not relevant to current issue?
2. Is it reasonable to assume it's a matter of buying and replacing the o2 sensor (PN 27729-10) and seeing if that resolves the issue or is there more diagnostic that could be done to verify the cause?
3.I have a Power Commander 5 unit on this bike and I'm wondering if there's any corrolation between the Front Heated o2 Sensor reading and the PC-5?
I'd welcome any input from those who've been down this road.
Thanks,
