I replaced the battery month ago and since then 2 codes have remained persistent, P0455 & P0130. They were cleared but came back. I inspected all vacuum lines and even flipped the gasket on the gas cap but no change. As far as the O2 sensors is concerned, all 4 were replaced less than 20,000 miles ago and now it appears to have impacted one of my cats because I hear the dreaded rattling noise but will take it to a muffler shop for confirmation. Will I need to replace the faulty O2 sensor? This episode puzzles me because all of this occurred after the battery was replaced, not to mention my coolant temp, fuel and rpm gauges work intermittently now. Is the new battery the cause of these gremlins?
P0130 & P0455 Question

The battery in the car is used only for starting the engine and than it is just dead weight as the alternator maintain car voltage.
So no, don't blame those issues on the battery.
You are not giving all the details, but I have a feeling you replaced O2 sensors because you had troubles?
That would mean your CAT was messed up before and now it might be just the final stage. Could be coincidence as well

Sensors were replaced three years ago as a matter of maintenance. The post cat went bad at the same and was replaced then. But these are recent sensors so I don't understand how could this one sensor went bad. Now driver's side cat is bad.
Bare in mind that sensor CIRCUIT malfunction doesn't have to mean the sensor is bad.
I am not sure if the bad cat would ruing the sensor, but it is possibility. Bad sensor ruining the cat is common issue.
Than things go bad occasionally and that is how the life goes.
This way or the other you need new parts.

I just returned from the muffler shop. The passenger rear cat is bad. That's the same one that I replaced a few years ago. But when I searched my records, I realized it was installed with the Magnaflow 94004 converter(Pre OBD II compliant). Allexhaust.com at the time of purchase indicated this is the correct part. I called Magaflow directly and they said the 99205hm converter is the right part. This may explain why it was short lived and even throwing P0130 code. Wondering if the P0455 DTC is related. Anyway, I ordered the appropriate converter and will have it welded in. We'll see what happens.
