Engine speed sensor?? You mean the crank sensor? If that wasn't working, the engine shouldn't run.

Where is the sensor in question located?

Engine Speed Sensor - PCM input, magnetically senses the notch in the vibration damper as it spins.

Page 14-120 of the service manual.

Didn't even see that part I hate diesel so I'm not well versed in that part of Mopar :b

I saw that, but, it apparently didn't register properly.

I replaced the sensor and everything works perfect now.

To be optimistic...

I now know a lot more about this truck and own a spare PCM in case mine ever fails.

Awesome. Here's hoping it a permanent fix.
