Is it my crankshaft position sensor?

My 2002 wrangler 4.0, starts, run an few seconds, then shuts off. Code says crank position sensor. Does this sound right?

Doesn't sound right to me, probably need to replace your crank sensor.

A bad crank sensor has always left me dead in the water but maybe a temperamental one would allow it to run for a few seconds

Where would you start?

Where would you start?

I would start by testing the sensor...do you have a multi meter?

IF this problem occurs when the engine is warmed up; the electronics in the CPS could be temperature sensitive indicating it needs to be replaced.
To test the CPS I recommend to members in our Off Road group when having this problem; pour some cool water onto the CPS, wait about 5 seconds and try starting the engine.
IF the engine starts and stays running for a while and shuts off again after the CPS has warmed up again; then the problem is the CPS and needs to be replaced.
