The P0332 is a knock sensor code, P0430 is poor performance for the bank 2 catalytic convertor. The remaining 2 codes are for first a com failure between the TCM (transmission control module) and the ECM (engine control module).and the second is a CAN bus failure due to the lack of com between the 2 modules.
The first thing to do is to remove the TCM and clean the male/females connectors and examine it for water damage. The cowling drains are known for clogging and then water gets inside and drains on to the TCM. While you are at it I would clean the connectors to the ECM also. Once that is done clear the codes and see what codes return.
The TCM to ECM communication may be causing a false reading for the knock sensor and the cat as the ECM is trying to make fueling adjustments from bad info from the TCM
