ok guys got this fault code up which means primary oxygen sensor heater circuit malfunction.
swapped the 02 sensor and this cured the problem, until now. had a new sensor on and the same fault has come up after only a day. been given some vague advice that it might be a fuse.

does anyone know which fuse it is i am looking for as my fuse panel labeling is in japanese. i am not getting poor economy and i have been told the heater circuit is not important after the engine is warm.

any information is greatly appreciated

i have the same code on my d16z6 and well other than throwing the cel im getting excellent gas mileage well above 35mpg so i just ignore the light. And im on my third o2 sensor which is why i stopped caring..
