Code 0901
I checked the codes on the ECU today, and it came up with 0901, which is upstream O2 sensor heater fault (right bank). I dont quite understand what the heater fault part of it is. Can anyone shed some light on this one? Will changing the O2 sensor make it clear away, because it comes back on after a few minuets of driving.

Change your O2 sensor. O2 sensor codes pop up all the time on Maximas (Nissans, for that matter) and I've never found a wiring problem related to it. The O2 sensors must be getting made by some cheapo company somewhere, because the new Air/Fuel sensors are the same way.

Ive also got 0901 (awaiting pay day for a replacement) does anyone know if with this code (for the heater) if the ecu operates in open loop (or closed i dont remeber which pertains to our cars) or does it still read off of that sensor even though the operating temp isnt being controlled? im also assuming there will be a decrease in gas mileage and performance...correct?
