Yeah. Your fuel pressure is low. Spec is 6 bar at key on which is 87 PSI. You are at 3 bar which is 43 PSI. This is assume you have the 3.6L engine. Do you have the turbo engine?
The fact that you have a code for the sensor, could just be a faulty reading but the fact that you have cold idle issues, points to a mechanical issue which low pressure would make sense.
Let me know what engine you have and we can go from there.
