Make sure you get your part code number stamped on your ECU and get the same part number stamped on the replacement part.

Sometimes when there are a bunch of different, seemingly unrelated codes it may be due to a wire short to ground or a power issue.

On some earlier Hondas, a wire short on the alternator wire or oxygen sensor may blow a fuse in addition to causing several unrelated trouble codes. I wouldn't be moving toward replacement of the ECM/PCM yet.

Since you mentioned a mouse found in the air box, there is a possibility you have rat/rodent chew on some wires. I have to look up which year Accord; but, there was an issue with a certain sensor wiring that rats like to chew on; subsequently Honda revised the part by adding wire insulation to the harness for that sensor that was not as palatable for rats.

My guess is that you may have rat chew on some other wiring harness which may be causing your trouble codes.

On 7th generation Accord V6, some Odyssey and Pilots, the rats like to crawl in the warm space where the knock sensor is. The attachment shows info. related to the Accord V6.

For your Accord L4, it may be some other wiring that the rats may possibly chewed on. So, I would start looking for chewed insulation.

Honda sells rodent resistant tape with pepper to cover wires after repair:
