My CEL light came on and I got the codes checked from a neighborhood Auto Zone. My car seems to be running/turning on fine with no noticeable differences. Can anyone help me out with identifying these codes and any solutions. Please and thank you.

I have a Acura TL 2005 139k Miles

61-1
BATTERY VOLTAGE MALF

68-1
BRAKE SWITCH MALF

83-1
Engine Control Module

P0325

 

Looks like a knock sensor malfunction on bank 1.
