HO2S Circuit Low.
I know this means there is an issue with the heater circuit for the O2 Sensor. and I know its the rear O2 sensor. I've checked fuses 11,12,15 and done a visual inspection of the wire harness and found no issues. Is there anything else I should do before replacing the sensor? If I wait till next year to change it is it a problem? I'm catless and tuned stage 2 hpfp so I dont think sensor 2 even matters at all.
