I had the same problem with my '05 Stratus SXT 2.4 DOHC. I've replaced the cam pos sensor and it seems to be running fine right now. On the Dodge forums a lot of the guys say that you need to replace the crank pos sensor too. I've bought one of those just in case it comes back again. Hope this helps.

Sounds like you have a vacuum leak, a problem with the wiring, or a bad PCM. Check wiring for pinched, chafed, pierced, or broken wires. Make sure vacuum supply is good, and not collapsing when the vehicle is running. Beyond that, a trip to the dealer may be in order.

EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0402 code means that OBD detected an excessive amount of EGR.
You may notice drivability problems such as the engine may surge off idle. There may also be other symptoms.
A code P0402 most likely means one or more of the following has happened:
With a P0402, it is common for people to replace the EGR valve, only to have the problem return. The most likely solution is to replace the DPFE sensor.
