Possible O2 sensor problem?

[EclipseGSX13]

02 problem? Not sure if this is it, but my Palm is reading 0.02V and my S-AFC II is reading 0.025 in the #2 slot.

I know I should be around .91V so my question is, is there anything else it could be? or is it my 02 sensor.

Thanks

By #2 slot you mean the O2 sensor in the exhaust? Don't tune off that one, its only for emissions and always has low numbers like that

By #2 I mean on the s-afc2, as in the second reading from the top. According to my manual that is for the O2 sensor.

also, the #3 reading on my afc (third from the top) it reads about .45-.50V when warm. (and I would guess that would be a correct reading for the second O2).

Oh,okay,Sorry i dont have any experince w/ a SAFC however I do remember getting like .02 volts and really low numbers for my 2nd O2 sensor in the exhaust. I never think I got high numbers like .50 and such but my datalogger is MIA so I cant check on that for ya.

Yeah it was kinda confusing the way I wrote it.
On my data logger is the bank one for the first o2 sensor, and bank 2 for the second? If anyone knows this is should help me find out

Yea, bank 1 on the logger is the one right after your turbo, and bank 2 is the one after the cat. For some reason, the o2 sensor in bank one gives a 0.0v reading only at wot, but after the cat in bank 2 it reads .98-1.0. I'm getting a new one soon hopefully

Well I changed my O2 Sensor and Im still getting these same readings. Anyone know why that is?

It stays between .025-.030 on my safc. and .02 and 4% on my datalogger.
I was told i need to get it to .90, but im not sure why these readings are so far off?

The numbers will be different at different times. The front 02 should be switching from almost 1V down to almost 0V at idle. At WOT the 02 sensor should be near 1V

It doesnt change very much when not at WOT, it will only be from .02-.03 on the logger, and .025-.030 on safc. and at WOT its around .04

it doesnt very much at all like its suppose to

Did you put in an OE sensor?

i got it from buschur
