codes.........
(on fairly new sensors, even) and never saw
any correlation with misfires on my engine.
IF the O2 is functioning normally otherwise I
can't see that it would.
On a cold start the pcm monitors how long it
takes the O2 voltage to drop below 300mV.
If it does not within a certain amount of time
(time depends on other variables) then the
second time it happens the code sets.
LSS, when I get tired of it I just replace the
sensor.
