I have two codes showing up. P2034 Exhaust Gas Temperature Sensor Switch and P2023 Intake Manifold Runner Position Sensor/Swtch. I called Chrysler and they had not heard of either sensors. My car stalls intermittently. Sometimes it starts right up but sometimes I have to wait a few minutes. I already replaced the Crankshaft Position Sensor so it's not that. When that went out, the engine tried to turn over but wouldn't. My new stalling problem happens sometimes when Im driving. The car just dies. The lights stay on but nothing happens when I turn the key. It starts after a few minutes so it sounds like something cooling off? I'm baffled. Any input into this?

 

I would still be concerned about the crankshaft sensor.

I know that this happened to some of the owners back when the car first came out. Check the archives. One lady that had a yellow roadster in 2006 had the same issue...she no longer owns the car, but there is a thread on it on this web site...
good luck!!
