The first fault code do you mean p1296 if so that is a cooling system malfunction you will need to check the temperature sensor.

The fault code p0411 is a Secondary Air Injection System Incorrect Flow Detected

And the p0304 fault code is a misfire detected on cylinder 4 possibly a coil pack maybe a plug

code p0304 refers to cylinder 4 --misfire detected==causes engine mechanical fault--wiring--ignition/ fuel system--injector--ECT/MAF sensor--ECM

Fault Code:- P0443 Indicates a Power-train fault

P0441=EVAP Emission Control System Purge Flow Fault

May have to do with the charcoal canister that captures gasoline fumes from the tank. Check the hoses from the canister; if cracked or loose, this could be at fault.

P0443=No definition as generic or Chrysler in my list - Check Dodge forums.

Check the condition of the gas cap's gasket; this is a common point of failure.

evap purge valve fault is your p0443
p1693 is manu. controlled aux input output fault
p1693 is a code for an open or short to ground for the check engine light
does it light up when key is on? if so then it is a left over code from some previous repair attemt
the evap code wont prevent starting
check for broken timing belt
check for fuel in tank and that it has proper fuel pressure

danbalue, a code P1765 means Transmission 12V Supply Relay Control Conditions and P1494 means EVAP LDP Pressure Switch Fault Conditions.

I found info on the following codes:
P0443 - http://www.obd-codes.com/p0443
P1494 - http://www.check-engine-light.com/dodge

Good luck.
