"Hi from the newbie.
One of our D6-350 engines is coming up with an intermittent “crank speed sensor fail” alarm as well as “engine speed too high” (I may not have the wording exactly right there) We don’t have any service manuals but parts schematics show 2 camshaft/flywheel senders, one right at the back of the block and 1 tucked down near the crankcase breather. Does anyone have any idea which one is for the alarm? I’m assuming the other one is for the tachometer as this is still working when in the alarm state. Both these senders are close to an old water leak through the hatch (recently repaired) so I’m hoping it’s an easy find/fix."
