o2 sensors
i'm not sure if one of my o2 sensors is ok. they never seem to be in the same cycle allways in opersate, one will be lean the other rich of the switch point. also one switched between 400 and 500mv the other 300 and 800mv. is one of them out or faulty?
another question is bank 1 the drivers or passenger side? i'm in australia RHS drive also.
another question about stft. if 1 bank is -15% and the other -1% is 15% subtracted from 1 bank and 1% from the other or does it average over both? mine are about 10% different all the time.
Bank 1 coincides with cylinder no#1. So its the passenger side here in Aus.
The best sanity check is to switch sides with the sensors & do another log.
The Tremor at AIR
Also the PCM can control fuelling between the banks. The bank with -15% will be fuelled independantly from the bank showing -1% trims.
ok thats good. swaped them over one still acts alot dofferent to the other. is seems to function still it switches might just be a different brand dont know??
When you swapped O2 sensors left-right, did the trims also swap banks...?
the trims was actually from an exhaust leak. however they still switch different one swings from 200-800mV the other 400-500mV. and they arnt in sync but they have independent correction so that wouldnt matter so much?? not even sure that there is anything wrong with the one that swings from 400-500 it seems to work ok.
Some info here,
If it's of any help.
