Can a Low Battery cause check engine codes?

[OrangeMustangGt]

crapola .....The last time i drove my car was last thursday, and the car barely started. On the way to the Hardware store my car was running horrible, and the CE was on, i assumed i had gotten some sensors in the engine wet because i have no hood....however, it seems that my battery isnt holding a charge, it will barely start.

Anyway, i pulled the codes and got about 10 of em....i was like Wtf!!!!..... all of em were something related to lower voltage than expected at certain sensors.....anyway, i have to buy a battery, but i was just wondering can this happen?

I think you answered your own question. Yes low voltage CEL ='s no power. (or not enough)

This is one reason we use a 5 volt reference signal (to accomodate alternator fluctuation and system-state changes). The simple answer is to charge the battery or replace it and go from there. Write down the codes and clear the KAM (it would be hard not do since you are playing with the batery) and go from there.

Good luck.
