Checked the battery today and it was reading about 14.6 volts. Turned the car off and hen on t dipped to around 10 or so then back up turned on each thing and it would dip but come back. I erased the code started back up and the light came on re-read the code and t was the same thing. I cleaned the battery terminal off and still nothing. I tried the computer again and there is a mode to read o2 sensors so I did that and it came up: O2 Bank1 Sensor1. Could this be the problem? I’m not sure why it wouldn’t have come up under read codes unless the O2 sensors are a seperate read. Night run it to auto zone to have them check it also
