3.6 Codes issue & diagnoses

[ucijeepguy]

Thanks for the help so far everyone I really appreciate it. I bought a new fuse array and that resolved the problem for it to start and run.

I also removed the Aux battery completely. I taped up both the positive and negative from the aux battery as well as the aux neg at the main battery terminal, and pulled N42 fuse

I am getting some new codes now and wanted to get some input. Fortunately, nothing major it seems.

P0443 -EVAP System Purge control Valve 'A" Circuit.

P0420 -Catalyst system efficiency below threshold (Bank 1)

C212A-16 System voltage circuit voltage below threshold
P0562-00 System voltage low
P1DB1-00 TCM system voltage excessively low
U1428-00 Inaccurate engine torque received.

That might be garbage left over from the fuse array incident. I would clear them and see what if anything comes back.
