Yesterday, I braved the 90* heat and rode down to AMORENO's house to try and help him with a problem.
His 2004 has been running rough and occasionally quitting since he bought it used. It's a Canadian bike. The dealer has replaced the fuel pump and done other things and now wants to replace the ECM, yet they never even pulled the codes, or even knew how to!
The codes stored were 12, 13 and 19. 12 and 13 are injector 1 and 2. This makes sense, since the bike sat for several years before he bought it and probably was run on some old, bad gas. I think those problems are gone.
Code 19 is a CKP Sensor, or CranK Position sensor. Since the bike only has about 20,000km, (maybe miles, not sure), and the valves have never been done, I suspect the wiring, since nobody has been in there to "mis-adjust" the crank.
Anyway, we cleared the ECM of codes and went for a ride. The bike ran perfectly and the problem did not appear on our short ride.
Is it possible just clearing the codes fixed the problem? If it happens again, we'll check the wiring. If fine, try my old ECM, then replace sensor, if not an ECM problem.
Any other suggestions?
