No O2 sensor voltage B1-S1 at ecu
I have having trouble running rich out of the exhaust, when I plug the OBDII scanner into the port it reads that its not getting no voltage at the O2 sensor (lean bias) so now my fuel trim is super high and its running rich out of the exhaust. I checked the voltage from the 02 all the way to the ecu pinout and it was good. I have no codes and the car runs great, it wont pass smog though.
