P1374 Code
 

So my 2001 Alero is throwing a P1374 code which, from what I cold find online, indicates a possible Ignition Control Module issue or a crankshaft sensor issue. Anyone had any issues with this and what could be the problem (if it's not one of these 2 issues)? And yes.........I already know if it's the crankshaft sensor, it's going to be a (insert favorite expletive here) to get to as i've found out it's behind the pulley........NOT COOL GM!!!! Thanks in advance for your help!!
