Thread: Conzult RT o2 % output

What's your o2 reading in conzult at idle?

Should be 0.01-0.99 if your in closed loop otherwise at one same exact one. Why do you ask, O2 output from narrowband is fairly useless. If while regular driving you don't see the voltages jumping around from 0.01 to 0.99 then your O2 is not being used by the ECU properly. Which might mean a bad O2 sensor or bad ground.

What do you mean closed loop? I just installed a new o2 and wanna make sure it's working properly to cross it off my idle issue "potential" list.

Don't you worry about what closed loop means, just make sure voltages jump like he said and the sensor is good.

Although I'd like to know what closed loop means, the voltage suggests the o2 seems to be functioning properly. I was concerned with the output % being such a low number.

This a tuning section, information should be spread and suppressed.

Closed loop means your ECU is taking the O2 sensor readings and tuning your AFR's to 14.7. OEM sensors are Narrowband, as in they only know what 14.7. When your driving your O2 sensor voltage will jump between 0.01 to 1.00v, this is between rich and lean.

At idle the ECU doesn't always use O2 sensor readings, thus you wont see the voltage jumping around. This is why I said to monitor it while cruising.

Beautiful! Thank you Vadim! That just answered my question. my o2 reading at idle, if jumpy at all, just sits at 0%....but does jump around in the range you mention. I guess I can cross o2 off my no idle issue.
