code 1391 on chrysler town and country

Question

I have a chrysler t&c 2001 and the code 1391 comes up when the engine is cold and my van dies while in idle and also when driving until the engine temperature reaches normal driving temp. what causes this to happen/

Answer 1

P1391 Intermittent loss of CMP (camshaft position sensor) or CKP (crankshaft position sensor)

If the vehicle runs right when the engine reaches operating temperature, this mosre than likely will be the CMP sensor, when a sensor ages it loses it circuitry and not able to produce a proper signal for the ECM to see.
