12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle.  Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.

If you have the same pulley arrangement that most 4.0 engines have that pulley is an idler not a tensioner. Your power steering pump has a pivot bolt, and a slide under the pump. You adjust belt tension using the pump.

SOURCE: crankshaft sensor located 98 jeep grnd cher 4wd 6cy

it is located at the back of the engine on top of the transmission bell housing,the plug runs over to the passenger side of the engine bay and it comes out from behind the engine,you can actually get your hand on the sensor itself from under the hood on the drivers side,and i believe its a 13mm bolt holding it in,the new sensor will have a sticker on the end of it...leave it there,it is used for correct spacing between the sensor and the flywheel,hope this helps

Testimonial: "Everything was just like you said but as a not atleast for my jeep it is an 11mm not 13mm. Works great so far (keep fingers crossed) "
