Just finished pulling the codes out of my newly acquired 98 ultra. Came up with a code 56, crank/cam sensor. So how do I tell which one it is that needs replacing? I hate just throwing parts at anything until the problem goes away. I would much rather figure it out to the right item and just replace what needs replacing, ya know? Any help narrowing it down appreciated.
98??? Is that an Evo?? If so might want to post this on the Classic Evo Forum. Some pretty smart cookies there. Also, heard about crank positoning sensor being troublesome on the early twin cams.
Bike is still running, how do you clear the codes? Still need to know how to test each sensor i guess since the code only shows both. Problems are popping on decel, hesitation with cough like the old kehin carbs used to. Bad enough to make me crazy(er).

Disconnect the bat for half an hour is easiest. Pop on decel is usally a leak in the exaust at the head.
Cough on excel out the carb is lean mixture.
Is it carb or fuel?

Just pulled the same code on a friends '97 and I told him to check under the nose cone and see if there was any melted plastic. There was. $198.00 for the sensor. Problem solved.
The fun thing about diagnosing electronics, sometimes, is that when you refer to the factory tech info, they STILL give you several choices, so what has changed between the good ol' days when you had to guess, and now, with the wonder of modern electronics, expensive and troublesome as they are, STILL not telling you exactly what the problem is!
