Hi,

The code indicates low voltage, bank 1 sensor 1. Usually that is caused by a connection issue. Have you inspected the wiring to make sure there are no breaks or damage? Also, have you checked the sensor relay? See pic 1 for location.

As far as the check engine light, the code needs deleted using a scan tool. Do you have access to one?

Let me know.
