What are these O2 parameters for????

[CAT3]

O2 LR Average transition Time's (Got the banks down!)

O2 Time to activity

O2 RL-LR Transition Ratio ( and of course would be opposite of LR-RL!).

I was logging these, as well as O2 mv, mine stayed at 0 except for time to activity, was 53/58 from a cold start. Both transition times stayed at 0 though? Is that right? BTW, my car runs fine except the bad IAC.

O2 LR Average transition Time's (Got the banks down!)

This is O2 sensor lean-to-rich transition time. This is the amount of time in seconds that it takes the O2 sensor to swing from the low(lean) voltage constant to the high(rich) voltage constant. The R-L minimum value is 0.00 and the max value is .12. The L-R minimum value is 0.00 and the max value is .14. A value outside this range will report a fail condition.

O2 Time to activity

I would guess that this is the amount of time in seconds that it takes the O2 sensor to reach the low(lean) voltage constant.

O2 RL-LR Transition Ratio (and of course would be opposite of LR-RL!).

This looks to be the ratio between the amount of time it takes the O2 sensor to transition from the high(rich) to low(lean) and then low to high voltage constants.

I was logging these, as well as O2 mv, mine stayed at 0 except for time to activity, was 53/58 from a cold start. Both transition times stayed at 0 though? Is that right? BTW, my car runs fine except the bad IAC.

My O2 sensor R-L transition time is .05 and my L-R transition time is .02.

HTH.

Aaron, thanks for the input. Appreciate it.
