hi everyone i had this in for a service and as i usualy do i captured some waveforms for my files
and i thought that this oxygen sensor looks unusual to me. does anybody know what type of
sensor this engine uses and if this capture is
normal? it has 4 wires 2 black 1 white and a blue
which is the signal one. also the engine runs fine and there are no issues with the car.
thanks. george
