Well I noticed my check engine light came on tonight... As some of you might remember i reciently posted that I had MANY codes stored that made very little sence... BUT, I checked the codes tonight when i got home. and I now only have 1687 (No MIC BUS Messages ) and 0341 (CMP Sensor Signal ) I tend to fix the 0341 ASAP, I was wondering if i got the right sensor for it... I picked up a Crankshaft Position sensor from cummins... (it installes behind the starter on the engine block, am I right on this???

I was also wondering what the crap No MIC BUS Message means??? Thanks!
