I have been reading other threads concerning this code pointing to O2 sensor and the threads were talking about rough idling and such. My CRV runs excellent and gas mileage is same as it has always been, but code P1167 keeps coming up. Do I need to replace the sensor or I read about a fuse for heating system. Where is fuse located.
Any suggestions?

 

you need to replace your upstream o2 sensor. or sensor number one. replace that and you code will go away. i recomend genuine honda parts
