Chrysler Repair: Code 11, crank sensor, no doubt

Question
I have a 1997 intrepid that's not getting spark the check engine light code is 121155 so what would be the problem???

Answer
Hi Dakota,
The 12 means that sometime in the recent past the battery was disconnected (irrelevant unless you don't recall that being done). The 55 means 'end of fault code readout (just to verify that it did do a readout). The important code is the 11 which means that the signal from the crank sensor is not being received by the controller, which almost always means you need to replace the crank sensor. Tell me which engine and I can tell you where/how to do that if you don't know already. That no doubt explains the lack of spark.
