Re: O2 Sensor Trivia
All of the EEC-IV and EEC-V's were designed for O2's being present. The scalar that you are setting to turn it off may accept a value of zero, but the EEC may see that and know that it is wrong and reverts to some know value.
I am just guessing, but I don't think '0' is a valid number.

Re: O2 Sensor Trivia
Yeah, seems like I recall a discussion about it not working on the tweecer board, but I generally don't read 94+ threads....

Now, I pulled the codes yesterday and they are: P0156 Downstream Heated Oxygen Sensor circuit fault - Bank No. 2. P0161 Downstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2. Obviously the switch I turned off doesn't turn off the circuit continuity check. This brings me to my next question. If I just plug the O2 back in, but leave it hanging out of the pipe, will the heat circuit continously run? What about when the ceramics crack because of moisture, will it throw the light again?

Re: O2 Sensor Trivia
The A9L has a scarl that says something like "Num Of HEGO". That is the one that I was refering to.

Re: O2 Sensor Trivia
I wouldn't leave them hanging. Throw a post on the tweecer board and see what they say...

Re: O2 Sensor Trivia
Using the SCT software you have to turn both the rear o2 sensor switch and the rear 02 sensor heaters for both 02's. If you just turn rear 02 sensor off it will still code just as you've described.
