I wasn't aware there was one on the back of the motor until reading this. Sure enough, the epc shows one for the 119. I always thought the only crank position sensor was the one at the crank damper on the front, which I believe the epc called a TDC sensor (I presume now the two are different). A search on this forum for crank position sensor for the 119 doesn't reveal much information about it. Is this something that has been an issue on the 119?
