Replace ECM?

I am having multiple issues and considering replacing my 2016 Nissan Versa ECM. In October 2022, we correctly jump started the vehicle, but the battery exploded within seconds after it started. We replaced the battery and the battery fuse. Before and since this incident, we have pulled up multiple codes on the vehicle that related to various sensors. We have changed out the O2 sensor, the Mass Airflow Sensor, the Vacuum Purge Valve solenoid, The Throttle Body, changed spark plugs, and the Fuel Pump. The codes have also shown misfires, as well as low and high voltage on some of the sensors. The car's performance has declined over this time period to where now it is undrivable.

So my question is, does this sound like an ECM issue? if so, can this be repaired or should it be replaced?

There are companies on ebay that will test and repair your ECM and ship it back to you. I might call one of them up, explain your situation and see if they can help you.

Yet another option would be to take the guesswork out of the equation by taking your car to a reputable repair shop.

The sensors all having trouble is a solid indicator of reverse polarity between batteries and the ECM is likely scrap. No way would I be getting that one repaired, way too many things to check and you could have destroyed 50 circuits there.
