shaft position sensor
 

all of a sudden i am reading a lot about this issue... i never really recall it before.

I am wondering if i should add this 40 dollar part to my arsenal of spares... does it rank up there with the ovp and fuel pump relay as a necessary item?

..or do they rarely go bad?

Flywheel/crankshaft position sensor? ON the M103 that was a LOW fail part.

Now on the M112/113 engines that has a 5-10% fail rate.

thanks... i won't spend the money for a spare
