I have a buddy's 1999 FXDWG carbureted model that I am having a problem with, I throws a code 42.
Let me explain this from the beginning. We decided (as it has 10,000 miles on it) to throw chain tensioners and bearings inner and outer at it. He also had an intermittent code 42, cam position sensor shorted low, also a 56 CKP/CMP signal error (as the 2 sensors were not communicating). I cleared his codes (using scanalizer) and he rode it a day and the 42 came back. I cleared the code again and I rode it 52 miles. No codes thrown.
He decided he wanted me to replace the cam and crank sensors while doing the tensioner/bearing update (wanted him to do just the cam sensor first).
I replace the inner bearings with Torringtons. The outers I went with flat rollers on the primary and secondary cam. I replaced both sensors.
Upon startup it was throwing a code 42, but the light was a lot more constant than before.
I decided to check the harness from the sensors to the module. All omed out good (after figuring out I needed to unplug the MAP sensor as the red/white (below cam cover) and blk/white at the module plug, as the red/white are connected to MAP and CMP).
I did pull cam sensor and check how deep the sensor goes onto the cam gear trigger boss. It is only .070 onto it with a crude measurement from the lower cam sensor seat to top of trigger boss and measuring depth of sensor.
I don't think that the new bearing played any part as the spacer on the primary cam gear would keep the cam outboard as it rides on the roller edge.
Any Ideas? I will check back later as I have to go to a bike function.

Thanks in advance.

 

Finally figured this out. It was a bad module. Replaced with updated version 32719-01C.
