I have an 08 gt and I recently got LT headers installed and switched to NTK O2 sensors. Bank 2 sensor one isn’t reading and causing me to have P0155 error code; I’m trying to test the harness connector with a multimeter for a voltage reading but I’m having trouble finding the ground wire in the female connector does anyone know what color the wire would be or it’s location?
P0155
