I am trying to diagnose the root cause behind several different codes that the OBD scanner is reading. My car is running fine and great and one day the CEL comes on and I get worried. I take it to AutoZone and Advanced Auto Parts to get the code ran. At Autozone they showed me these codes:
P0606: ECM Processor Error
P0136, P0137 and P0138: Heated oxygen sensor - bank 1 sensor 2 circuit low voltage, circuit fault, and circuit high voltage.
P0300, P0301 and P304: Random cylinder misfire condition, cylinder 1 misfire detected and cylinder 4 misfire detected. (I cannot tell if the engine is misfiring if it is.)
C1241: Low Battery Positive Voltage or Abnormally High Battery Positive Voltage. (This makes me think that the battery is weak, it would make sense considering it the stock battery which is over 7 years old.)
My question is, is it possible that all of these codes be resulting from a weak/old battery and if I changed the battery it would solve the seemingly numerous problems?
