SOB, got a CEL on the way home.. P1165 damn it. I'll check wiring and connections but chances are I'll be coughing up $200 for a new Denso primary wideband O2 sensor.

Hmm maybe my mileage will be better after it's replaced if this one just died as I doubt it was working well right up until it died....if it is in fact dead and there's not just a bad connection. Is there a preferred sensor? I'm looking at this one https://www.autozone.com/engine-mana...784_3498_97999

Also any idea if the car goes into a default somewhat rich A/F mixture until the sensor replaced and code cleared?
