You are not implying that I said resetting the PCM will help make it easier to replace the crank sensor are you?
All I meant is that the negative battery cable should be disconnected before doing any thing that involves replacing sensors or any type of electrical component replacement. And while the procedure is performed and the cableis disconnected, the PCM will be reset upon re installation of the cable.

My 97 dodge ram 5.9 is throwing the same code. p1391
About 3 months ago i replace the motor with a NEWER one, new torque converter, sensor in tranny, new distributer, coil, cap, wires, plugs, cmp, ckp, basically everything that can be done on outside of motor is NEW!!! Even with new ckp, cmp, it is still throwing the code. when i take off from a light it shifts fine through first an second, then when it shifts to 3rd at about 40-45 mph it will drop back to second then a sec later will shift again an its fine till i start over again. This does not happen everytime but its something that i would like to get fixed cause it is my only means of transportation. Answers would be awesome thanks.
