Hello my name is ***** ***** thank you for your question.

The code P1145 is for the Bank 2 intake timing sensor. These are located on the top of the engine. There is one on each side. This is normally a sensor issue that causes this code. I recommend you get the sensor from the dealer as if you get a After Market sensor it may cause issues since after market sensors never tend to work properly.

As for the P0430 code, that is a Catt Converter code. You get this code when the rear 02 sensor starts to mimic the front 02 sensor. The rear 02 sensor should never mimic the front 02 sensor if the catt converter is working properly. So when the rear starts to show operations like the front 02, that is what triggers the code. So the Catt Converter for bank 2 will also need to be replaced.

Do you have any more questions on this?
