Not likely as that is a different code.

Yep, sure can.  That's one of the possibilities listed in the FSM, among
others:

Cam position sensor signal
Intermittent crank position signal
5-volt supply circuit shorted to voltage
5-volt supply circuit open
5-volt supply circuit shorted to ground
CKP (that's the crank sensor) sensor signal circuit shorted to voltage
CKP sensor signal circuit open
CKP sensor signal circuit shorted to ground
CKP sensor signal shorted to 5V supply
Sensor ground circuit open
Crankshaft Position Sensor
PCM

You'd need a wiring diagram to troubleshoot any wiring shorts and whatnot,
but if you want to roll the dice and just swap the sensor, it's on top of
the transmission bellhousing, passenger side, and is reachable through the
passnger-side wheel well, by removing the tire and the plastic inner liner.
Having removed this from a '00 Durango several times (been arguing
vociferously with a transmission for the last...  well, a while), I can tell
you that a 1/4+ drive, 1/4" allen socket, with a short (2-3") extension and
small 1/4" ratchet is the best way to remove the sensor.

The sensor sticks into the bellhousing a good amount (maybe 5"), so it's a
bit of trick to wiggle it out, but not impossible.  Before buying a new one,
disconnect the wiring, and with the ignition on, check for +5V at the
connector on pin #3, and ground on pin #2.  If you don't have +5V or a
ground, then you've got a wiring problem and need to track that down.
