O2 sensor on bank 1 sensor 1 showing 0 volts (brand new o2 sensor). The bank 2 sensor 1 working fine (brand new sensor). Any ideas why bank 1 isn't working? There's also oil on the connector wire on bank 1. Thinking maybe that might have fried the wire?

 

 

Swap left and right to confirm you have wiring problem and not an infant mortality problem.
