So a couple months ago I began noticing an occasional problem where my liberty CRD would not start when I turn the key. I found that if I waited a little bit and then tried again, it would start. I researched the condition and it seems that the crank position sensor will cause this problem. I checked my error codes and found P0335 set. so I ordered a crank position sensor and checked YouTube for a simple step-by-step. I found this video I want to share:
