P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.
A FixYa rating from you regarding my assistance would be greatly appreciated.

Not a big deal...You will need to drain the tank if there is more than 10% the total volume of diesel. If not, fill the tank with 90 to 92 octane and go ahead and run it. It will not have the same power and will probably smoke some but actually the diesel will help clean up the system some and definitly lube the parts. Its better to run a longer time with engine warmed up rather than short trips as diesel burns better hot. As you use the full tank, continue to "top off" to increase performance back to normal. If you have to drain the tank, just follow same procedure. Um green is for diesel...haha gotta give you a little ribbing.

Hi there:DTC 1300 - Igniter Circuit Malfunction (No.1)
A DIS (Direct Ignition System) has been adopted. The DIS improves the ignition timing accuracy, reduces high-voltage loss, and enhances the overall reliability of the ignition system by eliminating the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders simultaneously with one ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2 spark plugs is connected to the end of the secondary winding. High voltage generated in the secondary winding is applied directly to the 2 spark plugs. In one of the spark plugs, the spark passes from the center electrode to the ground electrode and in the other plug the discharge is in the opposite direction, i.e. from ground to center electrodes.
The ECM determines ignition timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the igniter controls the primary ignition signals (IGC) for all ignition coils. At the same time, the igniter also sends an ignition confirmation signal (IGF) as a fail-safe measure to the ECM.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
