you get the BRAKE
No, I'm talking about the O2 heater; it heats the element in the O2 sensor. It's there for emissions reason(helps the O2 get up to temperature for more accurate reading). If it's not hooked up(ie you use a one-wire O2 on a P06 or P28), it'll just throw a code for O2 Sensor Heater. On the P08, it won't even look for it.
The O2 heater is not connected with the engine heating/cooling system. If your coolant gets hot; then you can have heat.
What he is trying to say is, Bank1, sensor 2. (p1162) i beleive is the code, heated oxygen sensor. It is used after the catalytic converter normally and really doesnt affect your A/F ratio. The main o2 sensor on the other hand will. take it out and let it just hang. The car will run fine, it will just run super rich. I did this when I boosted my d16 in my old car. My fuel system had problems so I couldnt put it all in except for the pump, so to compensate (temporarily) i took the o2 out. But last I checked, obd1 runs with ONE o2 sensor, not two.
